The White Ring Nightmare
If you live in a hard water area, calcium deposits (limescale) are inevitable around faucets. On a polished Absolute Black countertop, these white crusty rings stand out like a beacon.
The Vinegar Mistake
Your instinct is to grab vinegar (acid) to dissolve the calcium. Stop! While Absolute Black is generally acid-resistant, many other black stones (like Black Pearl or dyed granites) will etch or lose their seal. Acid makes the polish dull.
The Mechanical Fix
Instead of chemicals, use physics.
1. Razor Blade: Lay a single-edge razor flat (low angle) against the wet stone. Gently scrape the heavy crust off. It won't scratch the granite (Mohs 7) but will snap the calcium (Mohs 3) off.
2. 0000 Steel Wool: This is "Super Fine" grade. Buff the area dry. It acts like a super-fine sandpaper that polishes the stone while pulverizing the remaining mineral deposits.
3. Prevention: Apply a hydrophobic sealer around the faucet area every 6 months to stop water from bonding to the stone.
