Granito Ultra+ is the product specifically for the removal of rust and oxidation from natural stones, sold in 1-litre bottles.
This cleaner has an effective action on any type of surface and specifically on beola, quartzite, serizzo and all those stone materials that have in their composition ferrous minerals that tend to oxidise – giving rise to yellowish haloes – due to contact with constant humidity or with the water present in the laying mixtures.
Granito Ultra+ can be applied both internally and externally and on laid surfaces rather than on work to be laid. This cleaner is recommended for use by stonemasons to remove file residues after cutting or to remove oxidation due to contact with metal materials. Do not use on limestone and polished marble.
