How to clean and unclog a kitchen sink

Maintenance:

Jones suggested pouring very hot water down the drain at least once a week. This can help prevent clog-causing build-up on the interior surface of pipes. Or, pour one cup of vinegar down the drain and let it sit for 30 minutes. Rinse with two quarts of very hot water.

Another option is to pour an enzyme drain cleaner, like Earthworm Family Safe Drain Cleaner, down the drain each month to stop clogs before they start. The enzymes in these cleaners break down the build-up in drains.

Before putting dirty dishes, pots or pans in the dishwasher, scrape them well and then rinse with cold water. This helps keep any remaining grease solid so it can travel through drain lines more easily. Using warm water emulsifies grease and as the grease cools while traveling through the line, it solidifies and coats the inside of the drain line. Over time, this build-up on the surface will lead to stoppages.

Stinky drains?

Pour a half-cup of baking soda into the drain and follow it with two quarts of hot water. Baking soda is a great cleaning agent and will absorb foul odors, too. There are also specialized products, like Lemi Shine Disposal Cleaner, that use natural cleaning agents to freshen drains.

How to unclog a kitchen sink:

Fill the sink with very hot water and leave it for one to two hours. The weight and pressure of the water may clear the stoppage. If not, use a cup plunger to force water through the clog and possibly dislodge it.

If you suspect a grease clog, a mixture of very hot water and vinegar can also help melt and remove the grease that’s blocking the pipes. Allow it to work for a few minutes then use a plunger to help move the clog along. You may have to repeat this more than once.

Or you can try a microbial cleaner, such as Bio-Clean Drain Septic Bacteria. “Stay clear of any type of drain acid,” James warned. “As a rule of thumb, anything you wouldn’t want to drink, you shouldn’t put down your drain because eventually it ends up in the water supply.”

How to clean and unclog a bathroom sink or bathtub drain

Monthly maintenance:

Once a month, remove hair from drains using either a Drain Weasel or a bent wire hanger.

Also available in a pack of two for $5 at Bed Bath & Beyond and for $9 at Walmart.

When using a regular wire coat hanger, straighten it out as much as possible and then bend one end to create a hook. Push the bent end through the drain and start fishing.

Regardless of which device is used, hair, and all the gunk that’s stuck to it, should pull out. Once it’s all removed, run the hot water.

Don't forget to clean pop-up stoppers in the bathroom sink and tub. Lift them from the drain, remove any debris, and scrub off gunk using an old toothbrush. Rinse and replace.

How to unclog a bathroom sink and bathtub drain:

  1. Remove the hair: Most bathroom clogs are caused by a build-up of hair and personal-cleaning products. The best way to remedy that is to remove the clog manually (see above).
  2. Flush with hot water: If removing hair doesn’t seem to work, try pouring a kettle of boiling water slowly down the drain. Pour it in two or three stages, allowing the hot water to work for several seconds between each pour. Take care to pour the boiling water directly into the drain.
  3. Call a plumber: If the above tips don’t clear the drain, it’s time to call a plumber. Pipes are sometimes clogged further down the line with years of accumulated grease build-up or even tree roots. These are problems a professional should handle.
