What’s That Gunk in Your Bathroom Sink?

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:
  • The grease and grime from soap scum and hygiene products can gunk up and slow down your bathroom sink drain.
  • 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.
  • 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.
  • 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.

3. Open Cabinet Doors

Keep cabinet doors under sinks open to allow warm air from your home to circulate around plumbing. This is especially important for sinks located on exterior walls.

4. Seal Drafts and Openings

Cold air sneaking into your home can make pipes freeze faster. Seal cracks, gaps, and openings near plumbing with caulk or foam insulation to block chilly drafts.

5. Drain Outdoor Pipes

Disconnect garden hoses, drain outdoor faucets, and shut off water to exterior spigots. Use faucet covers for added insulation to prevent freezing during the winter months.

6. Maintain a Consistent Indoor Temperature

Keep your thermostat set to at least 55°F, even when you’re away. Maintaining a consistent temperature helps ensure pipes inside your home stay warm enough to avoid freezing.

7. Prepare for Extended Vacations

If you’re leaving for an extended period, consider shutting off your home’s main water supply and draining the plumbing system. This precaution minimizes the risk of freezing and water damage while you’re away.

8. Know the Warning Signs of Frozen Pipes

If you notice reduced water flow or unusual sounds when turning on your faucets, your pipes may be frozen. Address the issue immediately by calling a professional plumber.
