3 Things to Know About Removing Calcium Scale From Pool Tile

Use a pumice stone for safe removal Keep the stone wet and use light pressure. It is a soft abrasive that won’t scratch glazed ceramic or porcelain pool tile, making it the safest tool for buffing off calcium scale without harsh chemicals.

Avoid vinegar and muriatic acid unless you are certain Vinegar can etch some tile finishes, and acid can ruin grout. Even mild acids may cloud glass tiles or damage natural stone.

Start with the pumice stone before trying stronger options Dip the stone in water, rub gently on the scale, and rinse. For very thick scale, a specialty calcium remover may be needed, but the stone works for most cases.
