MAR GEL PLUS – Rust Stain Remover for Natural Stone Surface

MAR GEL PLUS by Faber Chimica is a specialized rust stain remover formulated for use on natural stone surfaces such as marble, limestone, and travertine. Its gel-based formula allows for deep penetration into compact surfaces, even those with a polished or brushed finish. When Rust Stain Remover comes into contact with rust, it forms a purple compound that darkens based on the stain’s intensity. Following up with OXIDANT will help remove the purple residue, leaving the surface clean and stain-free. Read our blog on How to remove rust stains from pavers.
