How to Get Rid of Grease in a Kitchen Sink Drain


A concentration of grease in a drain can spell disaster. Unfortunately, it’s easy to get grease in the kitchen sink when washing dishes or disposing of old food. Unless you know what dissolves grease in a drain, you could be stuck calling a plumber for every little clog. Before calling in the experts from Patrick’s HVAC for a drain cleaning, here are some home remedies you can try on a grease-clogged kitchen sink.

How to Unclog a Drain that Has Grease in It

As soon as you notice grease buildup, put some DIY fixes to work. Don’t wait for a clog to become an even more severe problem or cause your sink to start backing up regularly.

How to Dissolve Grease in a Drain with Boiling Water

Boiling water is the quickest (and cheapest!) possible fix. Simply pour a pot or kettle full of boiling water down the drain, slow enough that you don’t splash yourself. The added heat should loosen the grease, making it easier to remove or sometimes flushing it entirely.

What Will Dissolve Grease in a Drain? DIY Drain Degreaser

You don’t need to buy a fancy drain solution when you can mix household cleaners instead. Simply mix 1/2 cup of white cleaning vinegar with:

1/2 cup baking soda


1/2 cup salt and 1/2 cup borax

Immediately pour the mixture into your kitchen sink drain and let it sit for 15 minutes. Flush the drain with hot water, then cool water to completely clear the grease.

Can You Put Degreaser Down a Drain?

Avoid using chemical degreasers whenever possible. The harsh solutions can erode your pipes over time, leaving you vulnerable to leaks or burst pipes later. The best way to clean grease from drains is with an enzymatic or biological cleaner

Removing Grease Stuck in a Drain Manually

If nothing else works, you can try physically removing the clog from your drain. A trusty sink plunger can help loosen or move the clog. Run water in the sink until it covers the head of the plunger, then plunge it like you would a toilet. Flush the sink with more water.

If you have access to a plumber’s snake, feed it down the drain until you feel resistance. Then crank the handle to break up the grease clogging your pipe and retract the hose. It should bring the large mass of the clog with it.
