The 14 Best Drain Cleaners of 2021 Review

Even if you never pour oil down your sink, pick out all those wayward grains of rice, and fish out hair from your drain cover, one of the drains in your home will eventually get clogged.

It’s just a nasty reality of living in a place with plumbing.

Toilets, laundry sinks, showers, kitchen sinks, and even washing machine lines are all victims of clogged pipes and drains.

But before you take to Google in search of a five-star rated plumber, there are some things you can do at home to remove the clog at a fraction of the cost. Figure out what’s causing your clogged drains, and then check out some of the best drain cleaners on the market.

My Review: Though the name of this product sounds like something out of a comic book, its fast-acting effectiveness is no joke. The high-density liquid clings to pipes while liquifying drain obstructions such as lint, paper, hair, fat, oils, and other organic matter.

The product works by changing the pH level of the obstruction and is primarily designed for toilets. However, you can also use it on sinks, tubs, and other main drain lines.

Working within minutes, this drain cleaner is safer than formulas which use chemicals like sodium hydroxide. You also don’t have to worry about any toxic chemical smells as this formula is odorless and non-flammable. It’s safe for all types of pipes, your septic tank, and is biodegradable as well.

The bottle’s dual chamber means you won’t have to bother with measuring cups. If you’re using the product as a sink drain cleaner or to unclog your tub, just empty one chamber into the drain. If you’re using the product as a toilet clog remover, you’ll have to use the entire bottle.

6. Black Diamond GET SERIOUS Grease Trap Treatment

Black Diamond Stoneworks Get Serious Grease Commercial Drain Opener

Shop or Read Reviews

Estimated Price $25
Volume of Product 1 Gallon
Safe for Septic Tanks Yes

My Review: A commercial-grade grease trap cleaner, this will burst through grease-clogged pipes with ease and effectiveness. The product uses bacterial cultures which produce enzymes that break down organic matter, converting them into water and carbon dioxide. Regularly using Black Diamond’s Get Serious Grease Trap Treatment allows the bacterial microorganisms to take up residence in the pipes. These colonies prevent or reduce the accumulation of fats, oils, and greases, which can, over time, cause a slow draining kitchen sink.

While Black Diamond’s grease trap cleaner can eliminate clogs, it is best used as a preventative measure against grease clogs. For best results, use this product at a time of day when water usage is at its lowest (i.e. overnight). The product is safe for grease traps, drains, and pipes of all composition. It also won’t cause any damage to your septic tanks. And although it is commercial grade, feel free to use it in your home as well.

Key Features:

  • Commercial grade
  • Biodegradable, odor controlling
  • Prevents grease clogs

Shop or Read Reviews

Estimated Price $50
Volume of Product Powder (up to 128 treatments)
Safe for Septic Tanks Yes

My Review: While human waste, food remnants, soap scum, grease, and other organic waste might sound disgusting to you, it’s food for the bacteria that make DrainScrub so effective. The best drain cleaner in powder form, you can use it in toilets, garbage disposal, outhouses, RV holding tanks, septic tanks, showers, tubs, sump pumps, and everything in between. You can use it on all types of pipes including older galvanized pipes as well.

This drain opener even has extra vitamins and micronutrients to ensure that the enzyme-producing bacteria have a balanced diet. A proper diet allows the bacteria to have a fast metabolism, which, in turn, means that your drain can get unclogged quicker.

Water-to-powder ratios vary depending upon the location of the drain, so be sure to follow the directions on the container. For best results, refrain from using the sink, shower, tub, or other clogged drains for at least six hours after applying the treatment.

Key Features:

  • Eco-friendly
  • RV and boat-friendly
  • Powder, free of harsh chemicals

My Review: Designed to liquefy grease, hair, paper, and other organic matter, this is one of the strongest drain clog removers that is non-acidic. It works by creating heat that melts the grease that creates a slow draining kitchen sink. Instant Power’s product works great on all types of pipes, including PVC, and is safe for your septic tank. You can use it in your showers and tubs as well. Unlike many other drain clog removers, this formula does not smell harsh and toxic and will even remove pet hair from a clogged washing machine line!

For best results, use the product overnight, when water usage is at its lowest. The longer the product remains in the drain, the more buildup it will dissolve. When you’re ready to flush the drain, do so using extremely hot, perhaps even boiling, water.

The product has a light, slightly earthy scent, so you need not worry about harsh, toxic-smelling chemicals in your home.

Homemade Drain Cleaners

Despite claims by manufacturers that their products are not harmful, there is a certain peace of mind that comes when you make your own products and know exactly what goes into them. A natural drain cleaner might be your best bet if you’re on a tight budget or simply like to know what products you and your family are inhaling and ingesting. With that said, here are a few recipes for homemade drain cleaners. Before using any of these, make sure you unscrew your drain screen and remove any visible blockages.

Baking soda and vinegar are essential for any DIY cleaning product. Here’s are a few natural drain cleaners that you can make with items you likely have in your pantry.

Baking Soda and Vinegar

Pour one cup of baking soda into the drain.

Add ½ cup vinegar into the drain, and immediately cover it with a plug or rag.

Let the mixture sit for 30 minutes, and don’t use the sink during this time.

After 30 minutes, flush the drain with hot (possibly boiling) water.

Tough clogs might require multiple cleansings. You could also do this regularly as a preventative measure.

Baking Soda and Salt

Combine ½ cup table salt with ½ cup baking soda. Pour mixture down the drain.

Allow the mixture to sit for approximately 30 minutes, but the longer you let it marinate, the more buildup you’ll unclog.

Flush with a pot of boiling water.

Salt + Borax + Vinegar

Pour ¼ cup salt and ¼ cup Borax down the drain.

Follow with ½ cup vinegar.

Pour a pot of boiling water down the drain.

Allow the mixture to sit for an hour.

Once the mixture has cleared, allow hot tap water to flush away any remaining solution.

The Bent Wire Hanger Method

If the only thing in your pantry is ramen noodles, and you don’t want to spend any money, then surely you own a wire hanger (or can get a free one from your local dry cleaner). The bent wire hanger is simple and surprisingly effective.

Just straighten out a wire hanger to the best of your ability. Then, bend one end to create a small hook. Push the bent end past the drain cover (or remove the drain cover altogether), and start fishing. When you’ve cleared out as much buildup as possible, flush the drain with hot or boiling water.

So there you have it: the best drain cleaners on the market and some you can make at home using common household items. Did you purchase any of these? Which was your favorite? Have you made any of these DIY drainer cleaners? Do you have a drain cleaning recipe of your own that works like a charm? Let us know by commenting below!

Drain Cleaner Buying Guide

Things to think about when choosing a drain cleaner

What is causing the blockage?

There are many kinds of obstructions that could cause a blockage in your drain. Food, soap scum, oils, fats, plastics, hair, and paper are all key culprits when trying to identify the cause of a clogged drain. Toothpaste, shaving cream, heavy items (i.e. tiny toys kids put in the drain) are also common causes of drain clogs. When shopping around for the best drain cleaner, first determine what is causing the blockage. The best drain cleaner for hair might not be the best drain cleaner for grease, for example.

Since you don’t have x-ray vision and can’t see through your pipes, a good starting place for figuring out what’s causing the blockage is good ole common sense. Got a clogged drain in the shower or tub? Hair is probably to blame. Is the kitchen sink draining a little too slow? All those pieces of food you shoved down the drain after doing dishes are back to haunt you.

Where is the blockage?

Before purchasing or using any liquid drain cleaner, be sure to read and follow the directions on the label. Some drain openers are better suited for dissolving grease whereas others work to clear paper build-up. Certain drain openers are safe to use in garbage disposals and others are not. Some can fix a slow draining toilet whereas others might wreck your porcelain throne, so be sure you read and adhere to the product instructions.

What kind of chemicals are used in the cleaner?

Some of the most effective drain openers are acids. While they are fast-acting and clear the blockage quickly, they are toxic, can cause pipe corrosion, and are dangerous for the user.

On the other hand, enzyme drain cleaners are safe to use but can take a long time to work. They function by introducing enzyme-producing bacteria into the pipes which digest food buildup, soap scum, grease, and other organic matter.

It’s also important to know which chemicals are in your drain cleaner because pipes can be made from different materials (PVC, copper, metal, plastic, etc.) and some pipes don’t do well with certain types of chemicals. Again, make sure you read and follow all the listed instructions. If necessary, do additional researcher or contact the seller before using.

What’s your budget?

All of the products on this list will cost far less than calling up a plumber, so that’s always a win. But in general, plastic drain snakes will cost less than liquid drain cleaners.

Tips for using drain cleaners

Do not use around small children.

Most liquid drain cleaners have some kind of scent. Even if the scent is mild, it’s best to avoid using these around children and pets.

The longer you leave the product in the drain/pipe, the more effective it will be.

Although many products tout their ability to instantly eradicate buildup and residue in your pipes, generally speaking, the longer you let the product sit in the drain and pipes, the better. If possible, use liquid and powder drain cleaners at night, when your water is least being used. This will give the product time to fully break down grime, hair, grease, and other clog-causing agents most effectively.

Do not use around open flames.

Most people know not to use chemicals around open flames, but in case you need a reminder, don’t use drain cleaners around open flames. Though many claim to be non-flammable, just play it safe and avoid using drain cleaners if there’s a fire nearby.

Store in a safe place.

Many of the products on this list are non-toxic. Nevertheless, it would not be a good idea for children or pets to get ahold of them. Be sure to store products like these out of reach of children and pets.

Use gloves and safety glasses when handling.

Again, though many of these products are non-toxic, getting some in your eye or otherwise ingesting the product could be dangerous. Latex gloves and eye protection are always a good idea in the event that some product splashes onto your hands or face.

Always read the label.

Not all drain cleaners are created equal. Some are acidic. Others use natural bacteria. Some can be used in garbage disposals; others cannot. Be sure to thoroughly read (AND FOLLOW) all of the directions on the label before using.
