Top 7 Best Drain Cleaners You can Buy Right Now [2023]
1. Liquid-Plumr Pro-Strength Hair Eliminator Gel
The Liquid-Plumr Pro-Strength Hair Eliminator Gel is designed with a thick oxidizing formula that tackles tough hair clogs in showers, bathtubs, and sinks. This product has earned high praise from experts, with Bob Vila naming it the “Best Overall” drain cleaner and Good Housekeeping awarding it “Best Drain Cleaner for Hair Clogs”.
Effectiveness on Clogs
This gel’s oxidizing formula is particularly effective at breaking down organic clogs like hair and food particles, although it doesn’t perform as well against grease. Dan DiClerico, director of the Home Improvement & Outdoor Lab at the Good Housekeeping Institute, explains:
“It’s an oxidizing cleaner, so while it’s very tough on organic matter like hair and food, it’s less effective on grease”.
Bob Vila’s testing team rated the product highly, giving it 5/5 for ease of use, 4.8/5 for effectiveness, and 5/5 for value. Paul Rankin, a Product Reviews tester, highlighted its performance:
“Its thick consistency clung to clogs and quickly dissolved hair and debris, yielding a clean drain.”
Safety for Pipes and Septic Systems
This gel is safe to use on PVC, plastic, metal, and even older pipes. It’s also septic-compatible, as its ingredients degrade quickly and do not harm septic bacteria.
However, there are some precautions to keep in mind. Avoid using it in toilets or garbage disposals, and never mix it with ammonia, toilet cleaners, or other chemicals, as this can release dangerous gases.
Price in USD
At $5.18 for a 16 fl oz bottle, available at Walmart, this product offers great value for its performance. Customer reviews back up its effectiveness, with an impressive 4.6 out of 5 stars from over 15,000 Amazon ratings. Walmart shoppers gave it a similar score (4.6/5 from 825 reviews), while Target reviewers rated it slightly higher at 4.7/5 from 1,593 reviews.
Many users highlight its ease of use and reliability. One Walmart reviewer, Manuchca, shared:
“It’s an essential item to have at home. It works very well… I followed the instructions, and the drain unclogged instantly… I highly recommended it”.
The straightforward application – pour it down the drain, wait 15 minutes, and flush with hot water – makes it a convenient solution for homeowners struggling with hair clogs, eliminating the need for professional help.
Next, let’s take a look at another popular option for tackling different types of clogs.
2. Drano Max Gel Liquid Clog Remover
Drano Max Gel Liquid Clog Remover holds the title of the #1 selling gel drain cleaner. Its thick, powerful formula cuts through standing water to target and dissolve stubborn clogs. Whether it’s a kitchen sink, bathroom drain, or laundry area, this product is designed to handle various household drainage problems.
Effectiveness on Clogs
The gel’s dense consistency allows it to stick to clogs, breaking down hair, soap residue, and other debris effectively. For minor clogs, results are often noticeable within 15–30 minutes. More severe blockages may require an entire 32 oz bottle or even an overnight treatment for best results.
Customer feedback reinforces these claims, with the product earning an impressive 4.5 out of 5 stars from 68,161 Amazon reviews. Many users highlight its dependability and strength, often describing their drains as working “like new” after use. One reviewer, Suave Nadav, summed it up perfectly:
“For quick, powerful, and reliable clog removal, Drano Max Gel is a must-have. It’s fast, effective, and easy to use, making it perfect for tackling stubborn drain issues.”
Next, let’s explore how this product interacts with your plumbing and whether it’s safe to use.
Safety for Pipes and Septic Systems
Drano claims that its Max Gel is safe for all common pipe materials, including plastic, PVC, and metal, as well as garbage disposals and septic systems. This is attributed to a special ingredient designed to protect against corrosion. According to the manufacturer:
“Drano® products are powerful enough to dissolve nasty clogs, but they will not harm your plastic or metal pipes, so there’s no need to worry. In fact, Drano® Max Gel Clog Remover contains a special ingredient that prevents pipe corrosion.”
However, some experts remain skeptical. The intense heat generated during the chemical reaction raises concerns among professionals. Express Septic & Drains notes:
“The makers of Drano claim that all of their drain cleaning products are 100% septic safe. However, it’s highly unlikely that you’ll ever find a professional plumber or septic expert that will ever agree with this claim.”
Price in USD
Drano Max Gel is priced to suit a variety of budgets and needs. The 32 oz bottle ranges from $5.17 to $10.49 (approximately $0.33 per ounce), while the larger 80 oz container costs $9.47 (about $0.12 per ounce). With multiple size options, it’s easy to find one that fits your household’s requirements.
Opinions on its value vary. While many customers appreciate its affordability and quick results, others feel it falls short when tackling more complex or severe plumbing issues. Whether it’s worth the investment often depends on the type and severity of the clog and whether it resolves the problem on the first try.
3. Green Gobbler Drain Clog Dissolver
Green Gobbler Drain Clog Dissolver relies on an eco-friendly enzymatic formula to tackle clogs caused by soap scum, organic matter, toilet paper, grease, and flushable personal care items.
Effectiveness on Clogs
This solution uses enzymes to break down and liquefy common clog culprits like soap scum, hair, organic debris, and toilet paper. Many users have praised its performance, with one reviewer noting it worked better than Drano for clearing hair clogs, and another sharing that leaving it overnight successfully cleared their drain. That said, some users report mixed results – while it often improves drainage, it may not fully eliminate severe blockages, occasionally leaving drains to run slower than desired. However, regular use seems to help reduce future clogging issues.
Now, let’s look at how this product impacts your plumbing systems.
Safety for Pipes and Septic Systems
Green Gobbler is designed to be gentle on pipes and safe for septic systems. The formula is non-corrosive and free of bleach, making it suitable for various pipe materials like PVC, ABS, copper, and cast iron. Unlike harsh drain cleaners that require protective gear, this product is safer to handle during application. It’s also septic-safe, which is an essential feature for the approximately 25% of U.S. households that depend on septic tanks for wastewater management. As the company puts it:
“If you’re looking for the right stuff that’s tough on clogs but easy on pipes, drains, and septic systems, Green Gobbler is your easiest choice.”
Environmental Impact
Green Gobbler incorporates biodegradable surfactants and avoids producing fumes, making it safer for both your plumbing and the environment. However, while its ingredients are biodegradable, the formula as a whole is not entirely so. The National Advertising Division (NAD) has reviewed and confirmed the evidence supporting its “biodegradable” claim, which applies specifically to the product’s contents and not its packaging. By steering clear of corrosive chemicals like bleach and sodium hydroxide, Green Gobbler aligns with the growing demand for safer, more sustainable plumbing solutions. This enzymatic approach offers a gentler alternative to traditional chemical-based cleaners, striking a balance between effectiveness and environmental care.
4. Santeen Sulfuric Acid Drain Opener
Santeen Sulfuric Acid Drain Opener packs a punch with 93% virgin sulfuric acid, delivering a solution with a pH of 1.59 to tackle even the toughest clogs.
Effectiveness on Clogs
This drain opener has been tested extensively, showing its ability to dissolve 80% of hair and organic matter, 40% of grease, and 76% of paper products. Users back up these findings, sharing success stories of clearing severe clogs with just two applications and resolving stubborn blockages after a 24-hour treatment.
CNET’s testing team also gave it high marks. Gianmarco Chumbe, Laboratory Technical Project Manager, noted:
“The Santeen Sulfuric Acid Drain Opener proved to be the most potent among all the chemical drain cleaners we tested…”
For best results, the manufacturer advises using only half the bottle per application, which means a single 32-ounce bottle can handle two treatments.
Safety for Pipes and Septic Systems
When used as directed, Santeen is safe for PVC, ABS, cast iron pipes, and septic systems. However, it’s important to handle this product with care. It may discolor metal sinks, and proper ventilation is essential during use.
One user reported experiencing skin burns and recommended rinsing immediately with water and washing with baby shampoo if contact occurs. The manufacturer emphasizes avoiding contact with skin and eyes and using the product in a well-ventilated area for safety.
Environmental Considerations
Given its strong chemical composition, Santeen requires careful handling. Thoroughly flushing pipes and ensuring proper ventilation are a must. Due to its aggressive nature, this product is ideal for tackling severe blockages rather than for regular drain maintenance.
Price in USD
A 32-ounce bottle of Santeen costs between $36 and $78. For those looking to buy in bulk, a six-pack is priced at $60–$100, while a gallon option is available for around $29.99. With half a bottle recommended per treatment, the cost per application ranges from $15 to $39.
Customer reviews reflect strong satisfaction, with an average rating of 4.5 out of 5 stars on Amazon (from 43 reviews) and a perfect 5 out of 5 stars on Walmart (based on 4 reviews). This drain opener is best suited for severe blockages when other cleaners fall short.

5. Endure Enzymatic Drain Cleaner
Endure Enzymatic Drain Cleaner takes a biological route to keeping drains clear by using Bacillus cultures to break down organic clogs into harmless carbon dioxide gas. Unlike many enzyme cleaners, it doesn’t just shift grease and fats – it converts them into CO₂ for a more lasting solution. This makes it especially useful for kitchen drains. During testing, it performed exceptionally well in removing long-term grease clogs.
Effectiveness on Clogs
Thanks to its specialized formulation, Endure doesn’t just push clogs further down the drain; it eliminates them entirely. This makes it a powerful tool for tackling stubborn grease buildup, particularly in areas prone to frequent clogs.
Safety for Pipes and Septic Systems
Endure is designed for monthly use and is safe for both metal and PVC pipes, as it avoids the harsh chemicals found in many traditional drain cleaners. Instead, it uses bacterial cultures and enzymes to dissolve organic matter without causing damage. Additionally, it supports septic systems by replenishing beneficial bacteria. According to government data, typical sewer bacteria digest only about 40% of biodegradable waste, but specialized bacterial cleaners can achieve close to 100% digestion. For best results, pre-treat your drain with baking soda and hot water, then dilute the cleaner and let it sit for at least six hours.
Environmental Impact
Endure’s natural enzymes and bacteria provide an eco-friendly alternative to chemical drain cleaners. Its biodegradable formula helps prevent environmental harm while maintaining a healthy septic system. As John The Plumber highlights:
“Compared to chemical drain cleaners, enzyme-based drain cleaners are an environmentally friendly alternative.”
Price in USD
With monthly use, Endure minimizes the need for repeated applications and helps avoid expensive plumbing repairs. This makes it a cost-effective option that not only safeguards your pipes but also saves money in the long run.
6. Bio-Clean Drain Septic Bacteria
Bio-Clean takes a biological approach to drain maintenance by introducing live bacteria into your plumbing system. With each dose, millions of bacteria are added, doubling in number every 30 minutes. These bacteria work quickly, consuming waste and converting it into harmless byproducts like water, carbon dioxide, and mineral ash. This process effectively tackles common clog culprits such as grease, hair, soap scum, food particles, paper, and cotton.
Instead of merely pushing waste further down the pipes, Bio-Clean actively breaks it down, leaving your drains clear and your plumbing system running smoothly.
Effectiveness on Clogs
Bio-Clean combines a four-enzyme formula with bacteria to deliver a powerful one-two punch against clogs. The enzymes immediately start breaking down organic waste, while the bacteria feed on the smaller particles left behind. This dual-action method ensures a deep clean and helps prevent future blockages when used consistently.
One Amazon reviewer, B. D. Young, shared that after just two applications, their slow drain was “running like new”. Another user, Rhone, reported that after switching to Bio-Clean due to septic issues, their system was flowing freely again within six months.
For best results, mix Bio-Clean with warm water and apply it when the drain won’t be in use for 6–8 hours. Monthly treatments can help maintain clear pipes and prevent new waste buildup.
Safety for Pipes and Septic Systems
Bio-Clean is safe for all types of plumbing, including PVC, metal pipes, and septic systems. Since it contains no harsh chemicals, it won’t corrode or damage pipes. Instead, it targets only organic waste, leaving your plumbing materials intact. Additionally, by increasing the breakdown of solids in septic tanks, Bio-Clean reduces the frequency of septic pumping.
One Amazon reviewer, Robert M., mentioned that his septic professional recommended Bio-Clean, leading him to add an entire container to his tank every six months. With a 4.4 out of 5-star rating from over 8,800 Amazon reviews, users frequently highlight its safety and effectiveness.
Environmental Impact
For homeowners mindful of their environmental footprint, Bio-Clean offers a sustainable alternative to chemical drain cleaners. Its biodegradable bacteria and enzymes break down waste into water, carbon dioxide, and mineral ash without releasing harmful substances into waterways. Unlike chemical cleaners that can harm beneficial bacteria and aquatic ecosystems, Bio-Clean is a safer, eco-friendly solution for drain maintenance.
Price in USD
Bio-Clean isn’t just effective – it’s also a cost-efficient option for long-term plumbing care. Because it digests 100% of biodegradable waste, fewer applications are needed compared to traditional cleaners. Regular use can help prevent costly plumbing emergencies and reduce the need for frequent septic tank pumping, making it a smart investment for your home.
7. Zep Drain Defense Pipe Build-Up Remover
Zep Drain Defense is designed for preventative drain maintenance, using a formula packed with enzymes and bacteria to gradually break down organic buildup. This helps keep water flowing smoothly through sinks, toilets, and showers over time. Instead of being a quick fix for clogs, it works best as part of a monthly maintenance routine.
Using it is straightforward – just pour 1 ounce into the drain and follow with warm water. A single 64-ounce bottle can last up to 21 months, making it a cost-effective option for homeowners who prefer consistent upkeep rather than dealing with emergency repairs.
Effectiveness on Clogs
Zep Drain Defense excels at keeping drains clear but isn’t meant for tackling serious clogs. Many users highlight its role as a maintenance product. Long-time user Jason M. shared:
“I have been using Drain Defense for many years…Drain Defense is a drain maintainer (helps keep drain open) and not a clogged drain opener.”
While some customers find it helpful for minor blockages, others note it struggles with older pipes or severe clogs. For example, Amazon reviewer Sandra L. Petro commented:
“It’s a product to use for what I pay for it. It works really well for clogs and drainage. It’s easy to use. The scent is good too.”
Safety for Pipes and Septic Systems
The enzyme and bacteria-based formula in Zep Drain Defense is safe for all plumbing systems, including PVC, metal pipes, and septic tanks. Unlike traditional chemical cleaners, it avoids corrosive ingredients, making it gentle enough for regular use without harming your plumbing. It’s also versatile, suitable for sinks, garbage disposals, RVs, and even grease traps.
Environmental Impact
If you’re mindful of the environment, Zep Drain Defense offers a biodegradable formula that breaks down buildup into harmless byproducts like carbon dioxide, minerals, and water. This makes it safer for local ecosystems while preserving beneficial bacteria in septic systems.
Price in USD
Pricing varies depending on the retailer. On Zep’s website, a 64-ounce bottle costs $39.99, which breaks down to about $0.62 per month for ongoing maintenance. Amazon offers a case of two bottles for $37.98. Some users have even noted that regular use has saved them money on plumbing repairs.
As loyal customer Joe K. put it:
“Been using Zep products for years. Great quality!”
Pros and Cons
Here’s a breakdown of the pros and cons of various drain cleaners, highlighting their strengths and trade-offs based on your specific needs.
Chemical drain cleaners, such as Drano Max Gel and Liquid-Plumr, are known for their quick action on tough clogs. However, they come with some drawbacks. These products can potentially damage older pipes, especially metal ones, and pose health risks if not handled with care. Newer PVC pipes tend to handle these chemicals better, but caution is still advised.
Enzyme-based cleaners, like Bio-Clean and Endure, offer a gentler alternative. They rely on natural processes to break down organic matter, making them safer for your plumbing and septic systems. The trade-off? They take longer to work, which might not suit urgent situations.
Acidic cleaners, such as Santeen Sulfuric Acid, are incredibly powerful but require extreme caution. In CNET’s 2025 testing, Santeen proved highly effective, dissolving 80% of hair, 80% of organic matter, 40% of grease, and 76% of paper products, with a pH of 1.59. While these cleaners handle severe blockages well, their strength raises safety concerns and increases the risk of pipe damage.
| Product | Effectiveness | Pipe Safety | Environmental Impact | Price Range |
|---|---|---|---|---|
| Liquid-Plumr Hair Eliminator | High for hair clogs | Moderate risk | Chemical formula | ~$8 |
| Drano Max Gel | High for most clogs | Moderate risk | Chemical formula | ~$9 |
| Green Gobbler | Very high versatility | Safe for all pipes | Eco-friendly | ~$22–25 |
| Santeen Sulfuric Acid | Extremely high | High risk | Harsh chemicals | ~$78 (6-pack) |
| Endure Enzymatic | Moderate, slow-acting | Very safe | Biodegradable | Variable |
| Bio-Clean Bacteria | Good for maintenance | Very safe | Beneficial bacteria | ~$50 |
| Zep Drain Defense | Preventative only | Very safe | Biodegradable | ~$40 |
When comparing products, you’ll notice a significant range in price and safety. Fast-acting chemical cleaners like Liquid-Plumr and Drano Max Gel are budget-friendly at around $8–$9 but may require frequent use. Green Gobbler, priced at ~$25, offers better long-term value with its eco-friendly formula. On the higher end, Santeen’s industrial-strength cleaner costs ~$78 for a six-pack. Maintenance-focused products like Zep Drain Defense, at around $40, provide value for ongoing preventative care.
Safety considerations are crucial when choosing a drain cleaner. Hair-specific cleaners are great for bathroom drains but may struggle with grease buildup, while caustic cleaners excel at breaking down grease but could harm certain pipe materials. Older metal pipes are particularly vulnerable to caustic formulas, whereas newer PVC pipes are more resistant. Enzyme-based options, though slower, are much safer and support sustainable plumbing practices.
Application also varies by product. Preventative solutions like Zep Drain Defense won’t clear an existing clog but are excellent for reducing future buildup. On the other hand, powerful cleaners like Santeen are ideal for severe blockages but aren’t suitable for regular use due to their harshness.
For grease-heavy kitchen sinks, caustic cleaners are often the best choice. Bathroom drains clogged with hair respond well to oxidizing formulas, while homes with septic systems benefit most from enzyme-based options. The key is matching the cleaner’s strengths to your specific plumbing challenge.

Conclusion
Finding the right drain cleaner means matching your specific needs with the most effective product. Here’s a quick recap of the top recommendations based on our analysis.
For everyday household clogs, Drano Max Gel is a standout option. Priced at about $9, it’s highly effective against grease and soap scum while being safe for plumbing and septic systems. Plus, it boasts an impressive 4.5/5-star rating from over 68,000 Amazon reviews.
If you’re dealing with severe blockages, Green Gobbler Drain Clog Dissolver is a solid choice. Lab tests confirm its ability to tackle tough clogs. While it’s priced higher at around $25, the effectiveness makes it worth considering for stubborn issues.
For bathroom drains plagued by hair clogs, Liquid-Plumr Hair Clog Eliminator is a go-to solution. At $7–$8, it’s specially designed to handle hair blockages and has earned a 4.6/5 rating from Amazon users. However, it’s not ideal for grease-related problems.
Kitchen sinks, often clogged by grease – which accounts for 47% of residential sewer blockages – can benefit from Green Gobbler Drain Opening Pacs. At $22, these pacs are highly rated, with over 7,400 five-star Amazon reviews. For older fixtures, though, consider gentler options.
Homes with aging pipes should opt for enzymatic cleaners like Bio-Clean. While slower-acting and priced at about $50, they’re safe for metal pipes and won’t cause damage.
For households focused on preventing clogs, CLR Clear Pipes & Drains is a reliable choice. At around $15, it helps maintain clear drains with regular use.
Dan DiClerico, director of the Home Improvement & Outdoor Lab at the Good Housekeeping Institute, highlights the importance of prevention:
“Especially during colder months, it’s critical to nip clogs in the bud, since backed-up pipes are prone to freezing and bursting, which can lead to thousands of dollars in repairs. Our advice to homeowners is always to try a plunger first, since a few vigorous pumps are often enough to suction out clogs, especially if you catch them early.”
FAQs
What safety steps should I follow when using chemical drain cleaners like Santeen Sulfuric Acid Drain Opener?
When working with chemical drain cleaners, prioritizing safety is non-negotiable to prevent accidents or harm. Be sure to wear protective gear – this includes safety goggles, rubber gloves, and long-sleeved clothing – to protect your skin and eyes from potential splashes.
It’s also critical to never mix drain cleaners with other chemicals, as this can lead to hazardous reactions. Make sure the area is well-ventilated to minimize exposure to fumes, and always stick to the instructions provided on the product label. Keep a water source close by in case of accidental spills that need immediate rinsing. Lastly, store the cleaner securely, out of reach of children and pets, to avoid any unintended contact.
How do enzyme-based drain cleaners work, and are they effective for all types of clogs?
Enzyme-based drain cleaners rely on natural enzymes and bacteria to tackle organic materials such as grease, food residue, and soap scum. These microorganisms essentially “eat” the organic matter, breaking it down into smaller particles that can easily pass through your plumbing system.
These cleaners are excellent for dealing with organic clogs and are ideal for regular upkeep. However, they may struggle with tougher blockages or those caused by inorganic materials like hair, grease buildup, or solid debris. Enzyme cleaners shine when used to prevent buildup and keep your drains running smoothly over time.
What are the best drain cleaners for homes with septic systems?
For households with septic systems, choosing the right drain cleaner is crucial to maintaining the system’s health. Natural and eco-friendly options, such as enzyme-based cleaners or biodegradable solutions, work well to clear clogs and reduce buildup without disrupting the tank’s bacterial balance. On the other hand, harsh chemicals like bleach or acid-based cleaners can interfere with the system’s functionality and should be avoided.
Beyond selecting the appropriate cleaners, regular upkeep is key. Routine inspections and pumping are necessary to keep your septic system running smoothly, helping you avoid expensive repairs and ensuring your plumbing stays in great shape
