Our best overall pick for a drain cleaner, Drano Max Gel Drain Clog Remover, is a simple and effective solution for many run-of-the-mill clogged drains, like hair in the shower or food in the sink. We also love FlexiSnake Drain Weasel Sink Snake Cleaner to physically remove hair and other sink-clogging debris. These are the best drain cleaners for every clogged drain or pipe in your home. Keep in Mind: Some tough clogs may require a second application. It’s safe for piping and septic systems, with a thick gel that sinks into standing water to the source of the clog. The drain cleaner helps dissolve hair, melt soap scum and grease, and eliminates other messy clogs. When you have a clogged drain, just pour this cleaner into the drain, wait 15–30 minutes, and run hot water to clear any further gunk out. Be sure to pour carefully, and rinse immediately if you get any on your hands. If the first pass doesn’t work, wait a few hours and follow the steps again. We picked this as our best overall drain cleaner because it works in almost every situation, it’s widely available, and Drano also offers a money-back guarantee if this product doesn’t work.

To use, just pour half a bottle into the clogged drain slowly, then leave it alone for two hours. With an odorless formula, you won’t have a kitchen or bathroom that smells like chemicals. After two hours have passed, pour boiling water down the drain, which should now be cleared of the clog. For bigger obstructions, let the formula sit overnight. We love this for sinks because it’s odorless, and the safe-on-pipes formula of Xion Labs drain cleaner won’t damage garbage disposals, pipes, or even septic systems. Since it’s designed to liquify fats, oils, lint, paper, hair, and other organic matter—common sink-clogging culprits—it’s the best drain cleaner for your sink.

This plastic drain snake is 19.6 inches long and is covered in barbs designed to grab hair, the biggest clogging offender in the shower. To use, just feed gently into your shower drain (you may need to remove the drain cap) and push it in until you hit the obstruction. The Vastar is constructed to flex around curves and go deep into your pipes. When you find the obstruction, either break it up or pull it out, and you should be all set. Be warned: Whatever you pull out of your shower drain may have a foul-smelling odor.

The drain cleaning kit also comes with five “grabber tools,” which are bright green, flexible tools you can use to physically dislodge any tougher clogs. As with many drain cleaners, for really tough clogs allow the powder to sit overnight to liquify any debris in your pipes. These packs are odorless, so you don’t have to worry about a heavy smell in the air. They work for bathroom and kitchen sinks, tubs, showers, toilets, and floor drains. Green Goblin packs are also a great choice to keep in an RV or vacation home in case of a clogging emergency.

The cleaner has a slight citrus scent from the natural oil in the formula, which works with the gel formula to stick to the sides of drains and pipes to prevent and neutralize clogs. Beyond just clearing out clogs, the product can also eliminate drain flies, which can be tough to get rid of in the kitchen or bathroom, as the flies lay eggs in the debris in drains. Rockwell clears the clogs, and the citrus oil kills flies in the process. The cleaner can also be used for soda fountain drip trays to unclog sugar clogs. This gel cleaner is safe for septic systems and promises to be easy on your pipes while clearing out clogs (and flies!). To use, pour along the sides of the drain, using about 4 ounces of liquid for a 4-inch drain. Repeat every other day for a week, then use once a week or as needed.

We love this preventative cleaner for shower maintenance, especially when multiple people with longer hair use the same shower and often find themselves standing in an inch of water while showering. While this product can (and should) be used on slow drains, it will not clear out a completely clogged drain, as it is a preventative formula. The brand promises it is safe for people, pets, garbage disposals, and septic systems, and it has been designated a “safer choice” by the EPA. Price at time of publish: $10 Form: Liquid | Weight: 42 ounces | Time Needed to Use: 5 minutes Keep in Mind: It’s more expensive than other options. Enzymatic cleaners work more slowly and gently than chemical-based cleaners, so you’ll want to use this overnight. Using natural bacteria and enzymes, enzymatic cleaners are formulated to digest dead organic waste found in your plumbing system. This product will basically eat all of the debris caught in your disposal, leaving you with a fresh-smelling sink and kitchen. The powdered product comes in a large canister. To use in your garbage disposal, mix 1 tablespoon of powder with 1 pint of water. Quickly pour it down the drain with the disposal on to allow the product to disperse on the sides of the drain, and then turn the disposal off. The environmentally safe cleaner has enough product for 100 drain treatments. It works best on slow-flowing drains or as a monthly maintenance product for keeping your garbage disposal clear. Price at time of publish: $50 Form: Powder | Weight: 1 pound (canister) | Time Needed to Use: Overnight Keep in Mind: The cleaner has a citrus scent. The powder time-release tablets not only run through the machine’s hose, but they also clean the pump, valves, tub, drum, and filter. Affresh will work for top- and front-loading washers, including high efficiency. To clean your washing machine, add one tablet to your empty machine and run a normal hot water cycle. Directions vary minimally between types of washers, so read carefully. The cleaner tablets work by foaming up in water and using surfactant chemistry to break up odor-causing residue and grime. The product does have a citrus scent, so if you’re not a fan of odors or have certain allergies, this might not be the right cleaner for you. To get the most of this product and your washing machine, use a tablet once per month.

What to Know About Drain Cleaners Before Shopping
Form
Drain cleaners come in many forms, including pourable cleansers to tools that are fed into drains. The two types of liquid cleansers you’ll see the most while shopping are chemical-based and enzymatic. Chemical-based drain cleaners work the fastest, but also have the potential to cause more damage. Depending on the type of pipes you have in your home, damage can occur when using chemicals. PVC pipes can warp or soften from heat generated by chemical use. For metal pipes, excessive use can cause pipes to corrode and, in extreme cases, cause holes to develop. Enzymatic cleaners will clear clogs more slowly and are usually less harmful to your plumbing. The bacterial enzymes in the cleaner slowly break down natural blockages, like hair and food, but might not be strong enough to dissolve a complete blockage. For other blockages, a physical cleaner—a long flexible tool—may be needed to dislodge clogs. Given the damage that drain cleaners can clog, it’s important to integrate preventative clogging practices into your cleaning routine after removing a clog, so you don’t have to regularly rely on chemical drain cleaners.
Weight
This varies depending on the type of cleaner and what it’s being used for. Some cleaners suggest pouring the entire bottle on a clog,Other bottles or tablets are meant for repeat use. When shopping, consider if you have a one time only clog or if you’re dealing with ongoing issues.
Time Needed to Use
When shopping for a drain cleaner, consider if you need something unclogged quickly or if it’s not a pressing issue. Many chemical cleaners work fairly quickly, while others may take eight hours or a few applications to unclog drains.
Your Questions, Answered
Is drain cleaner safe for pipes?
For this, Kevin Busch, vice president of operations for Mr. Handyman, strongly suggests taking a proactive approach, telling us to stay ahead of clogs and use cleaners as directed. “Drain cleaner products vary but can be corrosive and have the potential to cause damage to your plumbing system (even metal pipes) if not used properly,” Busch says. “Your best bet is to never use drain cleaners but instead maintain your pipes to prevent clogs in the first place.” If a drain cleaner is necessary, make sure to start integrating preventative clog maintenance into your routine after clearing the blocked drain.
Can you use a drain cleaner for a dishwasher?
Using a drain cleaner in the dishwasher is not ideal, according to Busch; however, he offers a great tip. “The dishwasher’s drain hose and/or other components could be harmed by drain cleaners, which could result in leaks and other mechanical issues,” he says. “Sometimes simply running the garbage disposal might fix dishwasher draining problems. However, the problem is usually bigger than that and should be handled with care. It is recommended to call a professional to drain your clogged dishwasher.”
How often should you use a drain cleaner?
Busch again emphasizes the key to clearing out a clog with a drain cleaner is to follow the directions exactly if you don’t want to damage your pipes. “Since drain cleaners have the potential to cause damage, you want to be sure you follow manufacturers recommended instructions and never overuse a drain cleaner product,” he explains. “If after following the manufacturer’s recommendations your drain is still clogged, it is best to contact a professional to assess your situation.”
