Kitchen sinks tend to clog when grease is poured down the drains. Once the grease cools down inside the pipes, it turns into a solid mass that creates a blockage. You can prevent clogs caused by solidified grease by pouring grease in a can and disposing of the can rather than pouring the grease down the drain. If you have already poured grease down the drain and now have a clogged sink, you can dissolve the grease with hot water.

Step 1

Remove water standing in the sink by dipping it out with a plastic cup.

Step 2

Place a pot or kettle full of water on a burner on your stove and turn it on high heat. Allow the water to come to a full, rolling boil.

Step 3

Dissolve 1/2 cup of baking soda in 1 cup of water, and pour the baking soda mixture down the clogged drain.

Step 4

Pour the boiling water down the drain. Repeat this process until the drain is draining as it should.


Pour boiling water down the drain once every week to remove grease inside the pipes.
