Lithofin Rost-EX: Acid-Free Rust Stain Remover

What is Lithofin Rost-EX?

Lithofin Rost-EX is a mildly alkaline cleaner, specially developed to remove rust stains and other metal oxide residues. This product is effective on various surfaces such as clinker, ceramics, natural stone, marble, limestone, granite, gneiss, quartzite, concrete, and concrete stone. Lithofin Rost-EX works by converting rust into water-soluble substances, visible through a violet color. This allows rust stains to be easily rinsed off with water. The product is suitable for both indoor and outdoor use and does not leave visible changes to the surface.

How the product works

The action of Lithofin Rost-EX begins when the undiluted product is applied to the dry surface. It is evenly distributed with a brush and lightly scrubbed. The violet color indicates that the product is working. After 5 to 10 minutes of contact time, the product should not dry out. Add water and a few drops of Lithofin MN Cleaner (or some diluted dish soap), brush, and rinse off. Then thoroughly rinse with clean water. It is important that the contact time does not exceed 10 minutes. If the effect is insufficient, the process can be repeated multiple times.

Benefits and properties

Lithofin Rost-EX offers several benefits. The product is acid-free and mildly alkaline, making it safe for many surfaces. The reactive ingredients convert rust into water-soluble substances, which can be easily rinsed away. The visible violet color shows that the product is working.

It is suitable for both indoor and outdoor use and does not cause visible changes to the surface.
