Rust Removal

Remove stubborn rust stains from masonry and tiles

First of all, it’s important to know what rust stains actually are, and how they form.

Rust needs 3 things to form: iron or steel, water and oxygen. When iron or steel are exposed to water or humid air, a chemical reaction occurs, oxidizing the surface and creating flakes of iron oxide, which can range in colour from brown to red and orange. When rust sits on a surface for some time, it stains the material and can be difficult to remove.

In fact, rust can be found on all types of surfaces, from concrete to porcelain, marble and terracotta, in particular when they are installed outdoors and constantly exposed to humidity. Typically, rust appears as a dark brown stain, like the rings left from flowerpots on patio floors or nail marks in garages.

Many rust cleaners are acid based, which means they cannot be used on all types of materials. Acid based cleaners etch acid sensitive stone such as marble, limestone and travertine. Acid etching means that the acid actually eats away at the stone, making it appear dull and stained.

There are also rust cleaners for fabric which are at times applied on floor coverings. These cleaners contain hydrofluoric acid and are highly corrosive for floor surfaces. They even corrode porcelain tile! Therefore, they are not suitable for application on construction materials.
