A Clever Design with a Minor Drawback:
While the small hole on the sink is a practical addition, it isn’t without its challenges. Due to its position, this hole can become a hotspot for bacteria and mold, which may lead to unpleasant odors emanating from the pipes.
Keeping the Overflow Hole Clean:
If you notice an unpleasant smell in your bathroom, especially coming from this overflow hole, there’s a simple solution:
- Mix vinegar with baking soda and pour the mixture into the small hole.
- Allow the chemical reaction to work its magic for 5 to 10 minutes.
- Flush the sink with warm water to clean out the debris and freshen up your bathroom.
This quick and effective method will help you maintain a clean and odor-free sink, ensuring the overflow hole continues to serve its purpose without any unpleasant side effects.
