FABER MarGelPlus Water-Based Stain Remover 500mL for Rust Marks on Acid-Sensitive Surfaces Like Marble, Limestone, Travertine

Rust stains can make stone surfaces look older than they are, especially when they develop on materials sensitive to acidic cleaners. Restoring those surfaces requires a solution that removes rust effectively without compromising the stone. The Faber MarGelPlus Water-Based Rust-Stain Remover works specifically for marble, limestone, travertine, and other lime-based materials that demand gentle care. The gel penetrates compact structures, including brushed and polished finishes, to react with rust and produce a purple compound that indicates stain depth. This visual cue helps you monitor progress and determine whether a second application is needed. MarGelPlus performs well on marble–concrete agglomerate, marble–resin agglomerate, cement-based grout widths, concrete tiles, glazed ceramics, craquelé ceramics, and natural stone surfaces commonly found indoors and outdoors. Its thickened texture allows precise placement on walls, steps, vertical cladding, and narrow joints where liquid products may run or fail to maintain proper contact. The gel can be applied directly from the container or placed with a brush or spatula for targeted cleaning. After use, any purple residues can be removed with Faber OXIDANT to restore clarity and prevent discoloration. Because the formula is water-based and gentle on sensitive materials, there's no risk associated with harsh acidic treatments, making it ideal for both routine maintenance and corrective work on high-value stone.
