How To Clean a Bathroom Sink Overflow Hole

If you’ve ever looked closely at the back of your sink, you’ll find a little hole behind the faucet and near the back of the basin. The overflow hole in your sink is something that most people overlook.

However, understanding how this tiny bit of negative space works will help you maintain your bathroom sink clean and clear.

It, like every other part of your home, requires frequent cleaning and maintenance. In that manner, it can continue to vent while still preventing overflow. If you don’t, muck will accumulate at the bottom of the overflow channel, causing water to overflow from your basin.

Here are some of the best ways to clean and maintain your sink overflow system so that it can continue to keep water from overflowing even if the drain is clogged.

What is the Overflow Hole in Your Sink

The bathroom sink overflow drain is appropriately called because it prevents overflowing in your sink and is located at the back of the sink. It accomplishes this by redirecting water, allowing you more time to react before the contents flow over if you or a family member forgets to turn off the bathroom faucet or if there is a plumbing problem.

Why Do You Need to Clean the Overflow Hole?

The sink’s overflow hole on the bathroom sink isn’t just for show.

It serves an important purpose, and a clogged overflow hole is a quick way to a nasty disaster.

To function properly, it must be kept clean and clear of any buildup.

An overflow hole in your bathroom sink is required for various reasons.

Water is kept from overflowing by an overflow hole.
If you close the sink drain and leave the water running, or if you have plumbing problems, it will eventually overflow.

There’s a strong probability your bathroom won’t flood as long as there’s no dirt or mold in the overflow drain.

The Overflow Hole Aids Drainage
There is a suction effect when there is a lot of water covering the sink opening and no air can get through. As a result, the water flowing down the drain is extremely slow.

Another important role of overflows is to speed up the draining process. The overflow hole allows air to enter the drainpipe via the overflow channel, allowing the water to drain considerably more quickly.

How to Clean The Overflow Hole

As you might expect, keeping your bathroom sink overflow hole clean and clear of dirt is critical.

Overflows that are clogged can cause problems with the draining process and, not to mention, look unsightly in a clean bathroom sink.

Furthermore, if mold begins to grow in your clogged overflow, it will stink.

It’s a good thing the sink overflows are easy to maintain clean and foul smell free. Here are some tips for keeping the overflow hole on your bathroom sink clean.

Baking Soda and Vinegar

There’s no need to be concerned because a simple cleaning solution made from kitchen basics can remove both the muck and the stench from your bathroom sink overflow.

If you don’t want to use bleach to clean your bathroom sink drains, the soda and vinegar solution is a great option.

Baking soda and vinegar, two common kitchen materials, can be combined to form a DIY cleaning agent that keeps the sink overflowing spotless.

Follow this simple procedure to start cleaning your sink overflow with baking soda, any kitchen vinegar, and a funnel.

  • Pour 1 cup of baking soda into the small home via a silicone funnel
  • After the baking soda, pour cup of white vinegar into the hole.
  • Allow at least 10 minutes for the cleaning solution to rest in the overflow.
  • Fill the overflow hole with water and flush it out. Boiling water may be the most effective method for removing the vinegar odor. Allow all the gunk to flow into the sink’s drain and flush with warm water.

Liquid Cleaners

A basic liquid cleanser is another simple approach to cleaning a bathroom sink overflow hole.

Mix equal parts of plain water and whichever type of bleach you have on hand to make this solution. Pour the liquid cleaner into the overflow hole and wait a few minutes for it to do its job before flushing it out with water.

You can also use any ready-made liquid cleaner you have at home for this procedure.

Enzyme Cleaners

Brushing and blowing into the sink overflow can assist in the removal of any accumulation. But what if your overflow hole isn’t only plugged; it’s also stinking?

If you leave clogged drain unattended for too long, bacterial growth happens, causing a musty odor in your bathroom. You should use enzyme cleaners to keep the small hole in the sink clean and rid of any unpleasant odor.

These enzyme eaters consume organic bacteria, assisting in the removal of the bad smells from the overflow opening.

Fill the sink overflow drains with the correct amount of enzyme drain cleaner and leave it there overnight to allow the enzymes to digest the bacteria.

The following morning, flush the overflow hole with hot water to remove the filth and odor.

Rubber Hose

If you have a dishwasher hose or any rubber hose, you can use it to clear the overflow in your bathroom sink. It’s a simple way to get rid of a large buildup in the overflow hole of the sink.

Here’s how to clean the sink overflow hole this way.

  • Fill the bathroom sink with water until the overflow hole is just above the water level.
  • Insert one end of the rubber hose into the hole’s entrance.
  • Blow air into the opposite end of the hose in puffs.
  • After draining the sink, blow air into the hose once again.
  • Repeat as necessary until air freely flows through the overflow channel.

Cleaning Brush for Overflow

When the overflow drain and even the hole itself aren’t cleaned on a regular basis, gunk might build up.

This accumulation can obstruct air and water flow, but any dirt in the overflow hole can be removed with a simple cleaning brush.

To release as much muck as possible, a small cleaning brush with numerous bristles is ideal.

The bristles will also aid in the removal of any trapped debris that may be obstructing the overflowing sink.

If you don’t have a cleaning brush, a long zip tie could suffice. It’s flexible enough to go around the curve of the overflow channel while still being hard enough to shove any obstruction out.

How To Clean a Bathroom Sink Overflow Hole Bottom Line

It’s either the drain or the overflow hole that’s causing the smell in your bathroom sink.

If the overflow is the issue, there is a buildup of muck and trapped particles in the system. Not to mention the possibility that a bacterial kingdom already exists.

Fortunately, removing the blockage of filth and odor from your bathroom sink overflow hole is simple and can be done with most household items.
