FILA Deterdek Pro is a concentrated acid-based cleaner made for heavy-duty post-installation cleaning. It tackles tough residues like grout haze, efflorescence, lime scale, rust marks, and site dirt, without damaging acid-resistant surfaces. Unlike standard acid cleaners, this one’s buffered, so it won’t release harsh fumes or stain tiles and stone. It’s safe on aluminium and steel profiles when used correctly, and ideal for both indoor and outdoor use.
