Do you ever notice a musty odor coming from your bathroom sink?

The culprit may be the overflow hole, which is often neglected during cleaning.

In this article, we’ll discuss how to clean sink overflow to keep your bathroom smelling fresh and clean.

What Is the Purpose of the Overflow Hole in Your Bathroom Sink?

The overflow hole is a small opening located at the top of your bathroom sink’s basin.

Its primary purpose is to prevent water from overflowing onto the floor or countertop when the sink is filled to capacity.

How Does The Sink Overflow Work?

The overflow hole is connected to a drainpipe that leads to the same drain as the sink.

When the water level in the basin rises above the level of the overflow hole, it flows into the drainpipe and out of the sink.

This prevents water from spilling over the sides and onto the floor or countertop.

Why Do You Need to Clean the Overflow Hole?

Over time, the overflow hole can become clogged with debris such as hair, soap scum, and toothpaste.

This can lead to unpleasant odors, as well as the growth of mold and mildew.

To prevent your sink’s overflow hole from becoming clogged, it’s essential to clean it regularly.

Here are some tips to keep it clear:

After each use, wipe down the sink’s basin and overflow hole with a damp cloth to remove any soap scum or toothpaste residue.

Once a week, pour a mixture of baking soda and vinegar down the overflow hole to help break down any buildup.

Use a toothbrush or small brush to scrub the inside of the overflow hole, being careful not to scratch the surface.

Run hot water down the overflow hole to help flush out any remaining debris.
