Efflorescence & Limescale - Limestone/Travertine

Our efflorescence and limescale removal products are carefully formulated to safely address these mineral deposits on limestone, a calcite-based material that requires particular caution. Efflorescence appears as a white, powdery residue from salts in water, while limescale is a chalky build-up from hard water. Due to limestone’s sensitivity, selecting the correct acid is crucial to avoid surface damage. Traditional acids can erode and discolor limestone, so milder, specially formulated acids—like phosphoric acid—are recommended to effectively dissolve these deposits without compromising the stone’s integrity.

Proper product selection is essential for preserving limestone’s appearance and structure, and following detailed application instructions is key to achieving optimal results. In cases of stubborn deposits, allow the product to dwell on the surface, ensuring thorough dissolution while protecting the stone. PureSeal’s efflorescence and limescale removers provide professionals with the right tools to treat limestone effectively, restoring the stone to its clean, natural state without risk of damage.
