Have you spotted black stuff on your sink faucet? It often shows up around the spout, handles, or base — leaving your bathroom or kitchen looking dirty even right after you’ve cleaned it. This black buildup can be mold, mildew, soap scum, or mineral deposits. It’s not just ugly; it can smell bad and may even carry bacteria or mold spores that irritate allergies and asthma.
While cleaning helps, faucets with cracks, poor seals, or rough finishes often allow this black gunk to return again and again. If that’s the case, replacing your faucet with a modern, mold-resistant design is the best long-term solution. In this guide, we’ll explain what causes the black stuff, how to remove it, and recommend the best faucets ($300+) that are easier to keep clean and healthier for your home.
Quick Picks: Best Faucets to Prevent Black Build-Up
- Best Overall: KOHLER Purist Widespread Faucet – Smooth base, minimal seams, and easy-to-clean design.
- Best Budget: Moen Weymouth Widespread Faucet – Elegant look, durable finishes, priced under $350.
- Best Premium: Brizo Litze Widespread Faucet – Luxury-grade faucet with antimicrobial protection.
Why Is There Black Stuff on My Faucet?
The black buildup is usually caused by one or more of the following:
- Mold and mildew: Thrive in damp areas around faucet bases and handles.
- Soap scum: Leftover soap, toothpaste, or detergent mixes with moisture and grows bacteria.
- Mineral deposits: Hard water with manganese or iron can leave black stains.
- Old seals: Decaying rubber washers inside the faucet can break down into black particles.
How to Clean Black Stuff from a Faucet
If your faucet is in good condition, you may be able to clean the black buildup effectively:
- Disinfect: Spray white vinegar or hydrogen peroxide directly on the black buildup.
- Scrub: Use an old toothbrush to scrub seams, handles, and aerators.
- Soak Aerator: Unscrew the aerator and soak it in vinegar for 30 minutes.
- Rinse and Dry: Rinse with clean water and dry thoroughly with a cloth.
Pro Tip: Avoid harsh cleaners like bleach on metal finishes — they may damage the faucet surface and make buildup worse over time.
When to Replace Your Faucet
If black stuff keeps coming back after cleaning, your faucet may be the problem. Replacement is smart when:
- Buildup reappears within days of cleaning.
- The faucet finish is corroded, chipped, or pitted.
- Leaks at the base or handles trap moisture.
- The faucet has too many seams that are hard to scrub clean.

4. Should I check my water supply?
If the black stuff is coming from inside the faucet or water stream, check for mineral-heavy water or deteriorating plumbing parts.
