No doubt grout cleaner

Fila CR10 is a concentrated cleaner for fast removal of stubborn epoxy residue. It removes both new and existing epoxy grout - without leaving streaks or a telltale haze.

Available in one and five litre units, water-based Fila CR10 can be used on non-absorbent surfaces, including glazed ceramic tiles, porcelain and glass mosaics. Its non-aggressive formulation and gel-like viscosity make it safe and easy to apply to both floors and walls, internally and externally.

It can be applied directly to tiles, without damping the surface , promoting fast application. To remove old epoxy residue, a single disc cleaner fitted with an emulsifying pad can be used to gently buff the surface.
