Rust stain extractor

It can be applied to materials wth a very high concentration of rust, especially if it is present in the stone eg : Serizzo, Beola , Luserna and some granites particularly of Indian or Chinese origin. Do a preliminary test by allowing the product to act on the material for 30 mins. Later heat with a flame until the surface is dry. If the result is the disappearance of the rust then proceed to treat the whole material. If not then please contact the Kemistone technical dept.
