A dark ring around a faucet is usually caused by mineral deposits (hard water), soap scum, mold, or grime collecting where the faucet meets the sink. The best cleaning method depends on the cause.
Here’s a simple approach:
- Apply white vinegar. Soak a paper towel or cloth in white vinegar and wrap it around the base of the faucet for 15–30 minutes to loosen mineral deposits.
- Scrub gently. Use an old toothbrush or a soft-bristled brush to clean around the base.
- Wipe clean. Rinse with water and dry with a microfiber cloth.
- For stubborn residue, make a paste of baking soda and water, apply it, scrub gently, then rinse thoroughly.
If the ring won’t come off
- If it’s black or pink, it could be mold, mildew, or bacteria. Clean with an appropriate bathroom cleaner or a diluted bleach solution (following the product directions), then rinse well.
- If the discoloration is under the faucet base, water may be getting underneath. In that case, the faucet may need to be loosened, cleaned underneath, and resealed with plumber’s putty or silicone sealant.
Avoid using steel wool or abrasive scrubbers on chrome or brushed finishes, as they can scratch the surface.
If you can upload a photo of the dark ring, I can help determine whether it’s likely mineral buildup, mold, corrosion, or something else and suggest the best cleaning method.
