Grout Off is a special blend of acids and detergents specifically formulated to remove grout & mortar residues from porous and non-porous surfaces. Also effective for the removal of most hard water stains.

Unlike conventional hazardous acids, Grout Off is designed for safety when cleaning. 
Grout & Adhesive Tile Cleaner contains inhibitors to prevent fumes from attacking metal components associated with buildings. 

Grout Off is used to remove grout and cement stains from ceramic, porcelain, quarry, Saltillo, terracotta and other acid resistant tile and stone after grouting has taken place.

Grout Off must be diluted according to the below. No VOC (Volatile Organic Compound Formulas):

Light grout cleaning / Rust removal, dilute 1 - 30, covering 90m²

Medium grout cleaning, dilute 1 - 20, covering 60m²
