Mineral deposits are common in areas with hard water. Since stone (especially marble and limestone) is highly sensitive to acid, you must avoid typical household descaling products. Use a specialized stone cleaner or a paste made of a stone-safe poultice and water to gently dissolve the buildup. Once the deposits are removed, rinse the area thoroughly with water and buff it dry with a soft cloth. Regularly wiping down countertops after use helps prevent the accumulation of minerals in the first place.

Can mineral deposits be removed from stone countertops?
Yes, mineral deposits on stone countertops can often be removed using a non-acidic, stone-safe cleaner and a soft scrub brush or fine-grade nylon pad. Avoid using vinegar, lemon juice, or abrasive scouring powders, as these will etch and permanently damage the stone surface.
