How To Clean Sink Overflow Holes

The overflow hole in your sink is there to prevent water from overflowing and flooding your bathroom or kitchen. However, this small hole can easily become clogged with hair, soap scum, and other debris. A clogged overflow hole can cause water to back up into your sink and overflow, which can be a major inconvenience.

Fortunately, cleaning a clogged sink overflow hole is a relatively easy task. Here are a few simple steps on how to do it:

1. Gather your supplies.

You will need the following supplies to clean your sink overflow hole:

A small brush or pipe cleaner
A cup of white vinegar
A cup of baking soda
A pair of pliers
A flashlight (optional)

2. Remove the overflow cover.

The overflow cover is the small, round piece of metal or plastic that covers the overflow hole. Use a pair of pliers to gently pry the overflow cover off. Be careful not to damage the cover or the sink.

3. Clean the overflow hole.

Use the small brush or pipe cleaner to clean the overflow hole. Be sure to remove all of the hair, soap scum, and other debris. If the overflow hole is particularly clogged, you may need to use a pair of pliers to remove the debris.

4. Flush the overflow hole with vinegar.

Pour a cup of white vinegar into the overflow hole. Let the vinegar sit for 15 minutes. The vinegar will help to dissolve any remaining debris.

5. Flush the overflow hole with baking soda.

Pour a cup of baking soda into the overflow hole. Let the baking soda sit for 15 minutes. The baking soda will help to neutralize the vinegar and remove any remaining odors.

6. Rinse the overflow hole.

Use a cup of water to rinse the overflow hole. Be sure to rinse the hole thoroughly to remove all of the vinegar and baking soda.

7. Replace the overflow cover.

Once the overflow hole is clean, replace the overflow cover. Be sure to press the cover firmly into place to prevent water from leaking.

Tips:

If you have a flashlight, you can use it to look inside the overflow hole to see if there is any debris that needs to be removed.
You can also use a commercial drain cleaner to clean your sink overflow hole. However, be sure to follow the directions on the product label carefully.
If you are unable to clean the overflow hole yourself, you may need to call a plumber.
