How to Clean a Sink Hole?

To clean a sink hole (likely referring to a clogged drain), use baking soda and vinegar.

Here's how to unclog your sink drain using a common household method:

1. Prepare the Ingredients: You'll need baking soda and white vinegar. The recommended ratio is one part baking soda to two parts white vinegar.
2. Pour in the Baking Soda: Carefully pour about one cup of baking soda down the drain. This will help to loosen any build-up or debris.
3. Add the Vinegar: Slowly pour about two cups of white vinegar into the drain, following the baking soda.
4. Let it Bubble: The mixture will start to fizz and bubble. This is the chemical reaction breaking down the clog.
5. Wait: Allow the mixture to work for about 15 minutes. This gives it enough time to dissolve the gunk.
6. Flush with Hot Water: After waiting, flush the drain with hot water for several minutes to clear away any remaining residue and ensure the drain is clear.

If the clog persists, you may need to repeat the process or consider other methods such as using a plunger or a drain snake. If those don't work, you may need to call a professional plumber.
