Fila Deterdek is a powerful acid-based cleaner designed to remove tough residues such as grout haze, efflorescence, and lime scale from tile, stone, and masonry surfaces. It is particularly effective for post-installation cleaning, helping to eliminate construction dirt, cement residue, and inorganic stains. Despite its strength, Deterdek is formulated to be safe on delicate surfaces like porcelain, ceramic, and acid-resistant natural stones, without damaging grout joints. In addition to cleaning, it restores the original look of surfaces by dissolving build-up and enhancing their appearance. Ideal for both residential and commercial use, Fila Deterdek provides a deep clean while being easy to apply and rinse off.
