To remove colored stains such as coffee, wine, fruit juice, hair dye, ink and felt tip pens from porcelain and ceramic tile surfaces, you can use SR95 Stain Remover.
SR95 completely eliminates stains which normal cleaning products can’t get rid of. It is specifically designed to remove stains on natural stone (marble, travertine, agglomerates) and can also be used on polished stone without damaging its finish. It is also suited for cleaning low absorption ceramic tile surfaces like porcelain and single-fired tiles with a rough surface.
Removing stains with SR95:
Shake the product well before use. Completely cover the stain and let sit for 15 minutes, until it disappears. Remove any residue with a sponge. Should stubborn stains remain on marble surfaces, remove the product before it dries completely and repeat the application.
Alternatively, use PS87 PRO Heavy Duty Cleaner undiluted directly on the stain. Allow it to completely dry (20-60 minutes), then scrub vigorously with an abrasive pad. Rinse throroughly.
