This 750ml Grout Cleaner removes dirt from the wall and floor tile joints (glaze, terracotta, gres, marble, mosaic) including hard water marks. It can be used for cleaning both white and coloured joints. It creates a self-cleaning coating of nano-particles which actively counteract dirt and permanently protect the grout joints against dirt and water soaking. When used regularly it protects the cleaned surface even more effectively from dirt resettling. It has anti-static properties and it refreshes the colours of joints. It does not rinse off or discolour the grouting. It has a pleasant lemon fragrance. The trigger cap is sold separately.
