How does the pH of cleaning agents damage marble animal sculptures?

Marble animal sculptures are prized for their beauty and craftsmanship, but improper cleaning can cause irreversible damage. The pH level of cleaning agents plays a critical role in this deterioration. Marble is composed of calcium carbonate, which reacts with acidic (low pH) or highly alkaline (high pH) solutions.

Acidic cleaners (pH < 7) dissolve the marble's surface, leading to etching, loss of polish, and a dull appearance. Common household cleaners like vinegar or lemon juice can cause this damage. Conversely, strong alkaline cleaners (pH > 9) can also degrade marble over time, though more slowly.

To preserve marble sculptures, use pH-neutral cleaners (pH 7) specifically designed for stone surfaces. Regular maintenance with gentle techniques, such as dusting with a soft cloth, helps prevent long-term harm. Understanding pH's impact ensures these delicate artworks remain intact for generations.
