Method 1:

Boiling Water

The first method for unblocking a sink is to use boiling water.
This method is simple, quick, and effective for minor blockages. Here’s how to do it:

Boil a kettle of water.
Carefully pour the boiling water down the drain.
Wait for a few minutes to see if the blockage has cleared.
If the blockage persists, repeat the process.

Method 2:

Baking Soda and Vinegar

Another effective method for unblocking a clogged sink is to use a combination of baking soda and vinegar.
This method is also simple and can be done with ingredients you likely already have in your kitchen.
Here’s how to do it:
Pour half a cup of baking soda down the drain.
Follow this with half a cup of white vinegar.
Cover the drain with a cloth or plug and wait for 5-10 minutes.
Pour boiling water down the drain to flush out the mixture.
