Seeing black gunk on your sink faucet is never pleasant. It usually shows up around the base, aerator, or handles and can leave your sink looking dirty even when freshly cleaned. Worse, this gunk often comes from mold, mildew, or mineral buildup that thrives in damp areas. Not only does it look unsightly, but it can also cause odors and even contribute to health issues if left untreated.
While regular cleaning can help, sometimes the problem is tied to your faucet itself. Older faucets with worn seals, corroded finishes, or hard-to-clean seams can trap moisture and encourage black buildup. In this guide, we’ll cover why the gunk forms, how to clean it, and the best premium faucets ($300+) you can install to make your sink easier to maintain and more hygienic.

What Is the Black Gunk on a Faucet?
The black buildup you see is usually one of three things:
- Mold or mildew: Thrives in damp areas like around faucet bases and handles.
- Mineral deposits: Hard water can leave behind dark calcium or manganese stains.
- Soap scum and bacteria: Residue from soap and toothpaste combines with water deposits and grows bacteria.
This gunk not only looks gross but can cause musty smells and even harbor harmful germs.
How to Clean Black Gunk from a Faucet
If your faucet is in good condition, a deep cleaning may solve the problem:
- Disinfect: Spray vinegar or hydrogen peroxide directly onto the black buildup.
- Scrub: Use an old toothbrush to scrub around handles, bases, and the aerator.
- Soak Aerator: Unscrew the aerator and soak it in vinegar for 30 minutes.
- Rinse and Dry: Rinse thoroughly and dry with a soft cloth to prevent regrowth.
Pro Tip: Avoid harsh bleach or abrasive cleaners on metal finishes, as they can damage the faucet surface and make it more prone to gunk buildup.
How to Prevent Black Gunk from Coming Back
- Wipe your faucet dry after each use.
- Keep your bathroom or kitchen well-ventilated.
- Use filtered water if you have hard water problems.
- Replace old faucets with smoother, mold-resistant finishes.
