You can try to unclog your kitchen sink yourself by following a few procedures if it's clogged:
Investigate the garbage disposal. The clog may be inside your garbage disposal if you have one. Turn off the disposal's electricity and peer inside with a flashlight to inspect it. Use a plunger or a set of tongs to attempt to remove any trash or strange things you see.
Employ a plunger. Unclogging a kitchen sink using a plunger can be accomplished quickly and easily. To attempt to remove the obstruction, position the plunger over the drain and repeatedly pump it up and down.
Use a snake for the kitchen sink. A flexible, wire-like gadget called a "kitchen sink snake" can be used to unclog drain obstructions. To attempt to loosen and remove the clog, insert the snake down the drain and move it around.
Use a drain cleaner made of chemicals. If none of the aforementioned approaches clear the obstruction, you can try using a chemical drain cleaner. Use caution when handling the chemicals and adhere to the manufacturer's usage recommendations.
If none of these approaches succeed, the obstruction might be too severe for you to clear on your own. To unclog the clog in this situation, a plumber may need to be called.
