While beneficial, this overflow hole can also cause users some inconvenience. Since it is located in a somewhat awkward spot, it can easily accumulate bacteria and mold, leading to unpleasant odors rising from the pipes.
So, if you notice an unpleasant smell in the bathroom, especially coming from this small hole, you can mix vinegar with baking soda and place the mixture into the hole of the sink.
The chemical reaction will help remove the dirt from the pipes within 5 to 10 minutes. Finally, flush the sink with warm water to complete the cleaning process. This method will ensure your bathroom remains fresh and clean.
