How we chose

We compared what each maker says about pipe and septic compatibility, garbage disposal use, safety warnings, how fast each type works and how much effort it takes, and chose one tool or formula for each common kitchen-sink situation: a plunger, a fast gel, two enzyme treatments for grease and upkeep, and a hand auger. We did not test these products; facts come from manufacturer pages, labels and manuals, with any retailer data named.

What to look for in a drain cleaner

Start mechanical, then go chemical. A sink plunger is cheap, reusable and adds nothing to your pipes, so it is a sensible first step. Keep a gel or a hand auger for clogs a plunger cannot move.

Match the product to the problem. Gels and caustic cleaners are made to break through a full clog quickly. Enzyme and bacteria products work slowly on buildup, grease and odors and are best for slow drains and regular maintenance.

Check pipes, septic and disposal. Read the label for your pipe type, septic system and garbage disposal before you pour anything. Directions for disposals vary, so follow the one on the bottle.

Never mix drain products. Combining different drain cleaners, or adding ammonia or toilet cleaners, can cause splashing or hazardous gases. Flush one product out completely with water before trying another method.

Protect eyes and hands. Wear gloves and eye protection when using chemical cleaners or a drain snake, and keep all products away from children and pets. Know when to stop and call a plumber if the clog keeps returning.

Frequently asked questions

Which drain cleaners here are safe for PVC pipes and septic systems?

Liquid-Plumr says Pro-Strength Clog Destroyer is safe for all septic systems and pipes, including PVC, plastic, copper and old pipes. Zep's Drain Defense label says it is safe for all pipes and septic systems, and Green Gobbler says its enzyme cleaner is safe for all types of pipes and septic. The Korky plunger and RIDGID POWER SPIN+ use no chemicals at all.

Can I use these in a sink with a garbage disposal?

Yes, with each maker's method. Liquid-Plumr says to follow the normal directions and flush with the disposal running, while Green Gobbler says to pour it in with the disposal turned off and run water afterwards. Zep lists garbage disposals among its uses, and Korky's BEEHIVE Mini is made for sinks with or without disposals.

Should I use an enzyme cleaner or a gel for a fully blocked kitchen sink?

For a full blockage, the Liquid-Plumr gel is made to pour through standing water and work in about 15 minutes, or a plunger can push the clog through. Enzyme products such as Zep Drain Defense and Green Gobbler are aimed at buildup, slow drains and grease and are used as repeat or monthly treatments. If plunging and a gel fail, a hand auger like the RIDGID POWER SPIN+ reaches further into the line.

Is it safe to plunge or snake a drain after pouring in a chemical cleaner?

Be careful. Liquid-Plumr warns that its gel injures eyes, skin and mucous membranes, should not be splashed and must not be mixed with ammonia, toilet bowl cleaners or other clog removers. RIDGID tells users to wear latex or rubber gloves, face shields and other protective gear when chemicals are suspected in the drain, so flush the chemical away with water first and protect your eyes and hands.

What is the best way to unclog a kitchen sink?

Start with a plunger: the Korky BEEHIVE Mini Sink & Drain Plunger is the best overall pick, adds nothing to your pipes and works on sinks with or without a garbage disposal. If that fails, use a gel like Liquid-Plumr Clog Destroyer for a full clog, or the RIDGID POWER SPIN+ hand auger for a stubborn clog past the trap. Never mix drain products, and flush one out completely before trying another method.

What is the best drain cleaner for kitchen sink grease?

Green Gobbler Enzyme Drain & Grease Trap Cleaner is the pick for grease buildup: its bacteria and enzyme blend digests fats, oils, grease and food waste and contains no sodium hydroxide. It works over hours and repeated doses rather than clearing a full clog at once. For monthly upkeep, Zep Drain Defense is the maintenance option.

What is the best drain snake for a kitchen sink?

The RIDGID POWER SPIN+ with AUTOFEED is the hand drain cleaner here, with a 1/4 in. x 25 ft cable and bulb auger that feeds and retracts with a trigger. You can run it by hand or with a drill at up to 500 RPM. The manual says not to use it with a corded drill, and it requires safety glasses and leather work gloves.
