How to Remove and Neutralize Acid From Limestone

Natural limestone adds eye appeal, a durable surface and the interest of tiny fossils contained in the stone. Limestone is often used for floor and countertop surfaces but requires special care to stay in tip-top shape. You might think a strong acid would be needed to cause damage to a stone surface, but mild acids found in fruit juice and soda are enough to causing etching stains in your limestone. You can remove and neutralize acid on your limestone surface, and get rid of the damage by using proper cleaners and techniques.
