Types of Drain Cleaners

The three types of liquid drain cleaners are enzymatic, caustic, and acidic, each suitable for tough clogs in different drain locations and types of pipes and clogs. Some liquid drain cleaners are also designed for use with a drain snake to help deal with the stubborn grease clogs common in kitchen sinks.

To determine the clog type, remove the drain cover (if present) and inspect the drain opening with a flashlight. Clogs near the opening can be identified as hair, paper, etc.

Tip: If the clog is deeper, make an educated guess based on the clog’s location (kitchen sinks are magnets for food and grease, bathroom sinks and tubs often collect hair and soap scum, and toilets can accumulate paper products). Professionals sometimes use a drain camera and run it through the pipe to inspect the resulting images to determine the clog type.


Enzymatic drain cleaners contain enzyme-producing bacteria like bacillus that feed on clogs. They’re designed for monthly use to prevent clogs and also can clear clogs composed of soft material such as hair or paper, but not tougher gunk like grease or soap scum. However, they can take as long as 24 hours to clear even a soft clog. However, an enzymatic drain cleaner is eco-friendly and suitable for clearing septic systems.

Their generally gentle formulations are noncorrosive to newer and older plastic and metal drain pipes in sinks, showers, tubs, and toilets. They’re also typically free of harmful toxins and skin/eye irritants, so protective gear is usually not required.


Caustic drain cleaners are made with alkaline chemicals like sodium hydroxide, which convert the clog into a soap-like substance that dissolves under plain water. They’re best at removing food, grease, and soap scum from bathroom sinks, garbage disposals, showers, or tub drains—usually within 30 minutes, although most aren’t designed for use in toilets since they don’t handle paper products as well.

Caustic cleaners are considered safe for newer (less than 20 years old) plastic or metal pipes made of stainless steel or copper. Avoid using them in plastic pipes more than 20 years old (which they can soften), in older metal pipes, or pipes of any age made of brass, aluminum chrome, or galvanized steel, which they can tarnish or corrode.

While they’re less toxic than acidic cleaners (and usually odorless), they can burn the skin or irritate the eyes or nose with contact or inhalation, so wear a respirator, safety glasses, skin-covering clothing, and gloves made of a chemical-resistant material like butyl when handling.


An acidic drain cleaner is typically made of sulfuric or hydrochloric acid. These drain cleaners are powerful enough to clear heavy-duty clogs like hair, food, grease, soap scum, or paper-based clogs in 15 minutes or less. Acidic drain cleaners are generally safe for newer plastic or metal pipes (e.g., copper) in the sink, tub, shower, and toilet drains.

Don’t use them on older plastic or metal pipes or pipes of any age made of aluminum chrome, stainless steel, or galvanized steel. They can burn skin and irritate eyes and lungs if inhaled, so using safety gear—respirator, safety glasses, skin-covering clothing, and chemical-resistant gloves—is a must.

The Best Drain Cleaner Option: Drano Dual-force foamer clog remover, (Pack of 5)

Instead of a liquid or a gel, this caustic Drano drain cleaner is a foaming solution that expands when poured into the drain.

The method of application helps remove foul odors and works to dissolve hair, food, grease, and soap scum clogs. However, this method takes about 60 minutes to work. Additionally, the drain cleaner isn’t effective in standing water or toilets.

How We Chose the Best Drain Cleaners

To curate this list, we researched each drain cleaner product and analyzed the various chemical compounds and byproducts. Additionally, we considered the type of drain cleaner, the suitability of each product, and the average or expected working time of the product.

Generally, we chose drain cleaners with short working times, though we gave enzymatic products some leeway in this category because they are environmentally friendly, safe for septic systems, and won’t damage plumbing.

Caustic and acidic selections usually work within minutes, but the effectiveness of each product depends on its formula. Some can be used in standing water, septic systems, and garbage disposals, while others are limited to partial clogs. Additionally, we preferred products with features that make them more effective, such as a clinging gel instead of a liquid.

Tips for Using Drain Cleaner

Follow these guidelines to use drain cleaners safely and effectively.

  • Always read and follow the directions, adhering to specific amounts and dwell times. Never leave any type of drain cleaner inside drains for longer than the maximum dwell time. Chemical cleaners, in particular, can produce enough heat to melt pipes or crack porcelain toilet bowls if left too long.
  • Use caustic or acidic cleaners only in well-ventilated rooms. Turn on exhaust fans and/or open windows to increase air circulation.
  • Always stand outside of tubs or showers when pouring drain cleaner.
  • With the drain stopper removed, pour the drain cleaner as slowly and steadily as possible into the clogged drain.
  • If using a caustic cleaner, avoid exposing it to any natural stone surfaces surrounding a drain (such as a granite sink) to avoid etching it. For the same reason, don’t let acidic cleaners contact non-acid-resistant surfaces (like a marble shower floor or stainless steel sink). Some chemical cleaner manufacturers recommend applying a thin layer of petroleum jelly to the metal surface area around the drain to stave off discoloration or damage.
  • Never mix drain cleaners with other homemade or commercial cleaners; the chemical reaction that ensues could produce toxic gas or an explosion.
  • Flush any remaining cleaner with water at the temperature recommended in the manufacturer’s instructions.


For more information on the benefits and drawbacks of drain cleaners, as well as tips to help reduce drain clogs, take a look at some of the most commonly asked questions and the answers below.

Q: What clogs drains the most?

Many different substances can clog a drain; however, hair, soap, grease, fat, and oil are the most common. Tree roots are responsible for most drain clogs outside the home.

Q: Do vinegar and baking soda clean drains? 

Vinegar and baking soda don’t clean drains, at least not any better than using boiling water and dish soap. Since baking soda is a base and vinegar is an acid, mixing them creates a chemical reaction that produces water, carbon dioxide, and sodium acetate, which has an almost neutral pH level. It lacks any cleaning properties that could efficiently eliminate grease.

Q: Can drain cleaners damage pipes?

Yes, drain cleaners can damage the pipes, though it depends on the type of cleaner. Caustic and acidic drain cleaners are harsh solutions that are highly effective at clearing clogs, but they can damage older plastic and metal pipes. Both cleaners seem safe for newer (within the past 20 years) plastic and copper pipes. If you have older plumbing, consider using an enzymatic cleaner to avoid damaging the pipes.

Q: Can drain cleaners reduce odor?

Drain cleaners generally reduce odors because they help clear clogs and eliminate foul-smelling waste from the insides of pipes. However, since drain cleaners can damage your pipes, only resort to a caustic or acidic drain cleaner when an actual clog is present, not just a bad odor.

Q: How do I stop hair from clogging the drain?

The best way to stop a hair clog from forming is to use a drain cover. Routine cleaning and maintenance help prevent sticky grime and sludge from coating the walls of pipes.

Q: Will shaving in the shower clog the drain?

Shaving can cause or exacerbate a clog, especially if you use a thick shaving cream or high-lather soap. When you shave, rinse with hot water to help dissolve the soap residue left behind.
