Auro Mould Eliminator is pH neutral, solvent and chlorine free and non-caustic. Suitable for use on tiles, walls, wood and plastic, also in damp rooms. This is the first stage of the Auro Anti-mould treatment that eliminates the mould. Mould Stop then stops it from coming back and the Anti-Mould Paint is a final finish that makes the surface too alkaline. For more info visit the Tech Area of the RDE pages
