What is the best way to remove rust stains from my concrete surfaces?

Concrete surfaces, both indoors and outdoors, can develop rust stains from metal objects or iron-containing fertilizers. These stains are stubborn and can be difficult to remove without damaging the concrete surface. Traditional cleaning agents can be too aggressive and may damage the concrete. Therefore, it is essential to use a product that is specifically designed to remove rust stains without harming the concrete.

Apply Lithofin Rust-EX to the rust stains and lightly brush for effective cleaning

Lithofin Rust-EX is a mild-alkaline cleaning agent specifically developed for removing rust stains and residues of other metal oxides. The product works by converting the rust into water-soluble substances, which can then be easily rinsed off. For use, apply Lithofin Rust-EX undiluted to the dry surface and spread it with a brush. The violet coloring indicates that the product is starting to work. Allow it to work for five to a maximum of ten minutes, but do not let it dry out. Then rinse thoroughly with water and possibly a few drops of Lithofin MN Power-Clean or diluted dish soap. Repeat if necessary. Lithofin Rust-EX is suitable for use on all types of concrete surfaces, both indoors and outdoors. It is effective without causing visible changes to the surface.
