The dark ring around faucets is usually a mix of soap scum, limescale (hard water minerals), and sometimes mold. You can remove it pretty easily with common household cleaners.
1. Vinegar soak (best for limescale)
- Soak a cloth or paper towel in white vinegar
- Wrap it tightly around the faucet base
- Leave it for 30–60 minutes
- Scrub with an old toothbrush, then rinse
2. Baking soda paste (for stubborn stains)
- Mix baking soda + a little water to make a thick paste
- Apply around the dark ring
- Let it sit 10–15 minutes
- Scrub gently and rinse
3. Dish soap + warm water (light buildup)
- Mix dish soap with warm water
- Scrub with a sponge or toothbrush
- Good for regular maintenance
4. For mold (if it looks black/green and smells musty)
- Use diluted bleach (1 part bleach : 10 parts water) or hydrogen peroxide
- Apply carefully with a cotton pad or brush
- Let sit a few minutes, scrub, rinse well
Tips to prevent it coming back
- Wipe faucet dry after use
- Clean weekly with vinegar spray
- Check for small leaks around the base (they cause constant buildup)
If you want, you can tell me what it looks like (brown, black, green, hard crust, etc.), and I can pinpoint the exact cause and best cleaner.
