What's That Gunk in Your Bathroom Sink?

December 8, 2022

Clogged drains caused by black gunk can annoy and inconvenience everyone in the house, especially when taking turns getting ready in the morning! Bacteria feed off things like hair, hand soap, shaving cream, skin cells, moisturizer, toothpaste, and phlegm to produce the black sludge that builds in your drain.

Causes of Clogged Bathroom Sinks

When confronted with a clogged bathroom drain, the majority of people's first thought is the toilet or the shower drain. However, blockages also often develop in the bathroom sink. Three common culprits in persistent bathroom sink clogging are:


  1. The grease and grime from soap scum and hygiene products can gunk up and slow down your bathroom sink drain. 
  2. Although hair blockages are most common in showers and bathtubs, they may also cause problems with bathroom sinks if you shave or brush your hair over the sink.
  3. Because of its design, foreign items can get caught in the P-trap which is designed to prevent noxious gases from coming back up into your bathroom but can also trap some small items.
  4. A blocked main line can cause water and sludge to back up into your bathroom sink - a problem that is best left to a professional plumber. 

Keeping Your Bathroom Sinks Clear

Fortunately, clogged drains can sometimes be quickly fixed with some simple procedures Some suggestions include:



  • Use a plunger or snake.
  • Pour one spoonful of baking soda and a quarter cup of white vinegar down the drain and left for an hour before flushing.
  • If the sink is completely drained but clogged, try slowly pouring hot water down the drain to clear the blockage.
  • Periodically add bleach (or baking soda/white vinegar combo above) to the sink to help keep it clean and avoid future clogging issues.
  • Avoid rinsing hair down the drain, whether it's shaving or washing your hands after styling. Use a paper towel to catch whiskers or wipe off your hands before washing.

When to Hire a Professional Plumber

If you've tried many solutions to no avail, it may be time to bring in the experts to fix your clogged drains. A specialist with the necessary expertise and equipment can help you eliminate the issue at hand. This is especially important if the issue is from the main line or a result of other clogged drains such as your toilet or shower. ï»¿
