PolyKleen 9006 is a concentrated phosphoric acid cleaner used to clean cement grout lines. It removes grease, oil, mould and dirt from older grout. It must be diluted by 50% with water before use.

NOTE: Acid-based cleaners are very effective to remove stains, but they may, however, damage some types of floor coverings such as marble or limestone. Before using an acid-based cleaner, always amake sure that your floor-covering does not react to acid. It is important to test on a small area first to ensure that the selected product suits the surface that needs to be cleaned.
