Lithofin BERO - 1 LITRE

Granite Rust Remover (Acidic)

Lithofin BERO - 1 LITRE permanently removes rust and all discolorations due to rust, whether from the natural iron content or treatment. Mortar residues, film cement, slag sanding and other similar dirt will be eliminated. Lithofin BERO - 1 LITRE is also suitable for removing cement residues from iron containing natural stones.  Suitable for acid resistant hard stones.

Lithofin BERO - 1 LITRE should not be used on the polished marble, limestone, the eloxal, zinc or other materials sensitive to acid. On some natural stones, the color may become darker, but it will get back to normal after some time. If in doubt, always try on a discreet place of the surface.

The discolouration alters the appearance of the stone, which is undesirable from an aesthetic point of view. Rust stains are one of the most difficult marks to remove from stone paving slabs. They’re generally caused by metal objects – furniture, firepits, BBQ’s, garden tools, pots and parasol stands are common culprits. Contact with water washes deposits of iron particles onto the pavers which then leave a rust stain.   

It’s really important to use the correct stone cleaner and rust remover. For safe removal of rust – indoor as well as outdoors – we recommend Lithofin BERO - 1 LITRE Granite Rust Remover.
