HG rust stain remover easily and safely removes rust stains and other oxidation stains from all ceramic tiles, concrete, marble, roof tiles, metal and wood. The product does not contain acids and is therefore not only absolutely safe for the above surfaces, but also for marble, bluestone, concrete stone and other calcareous stone.

Use HG rust stain remover on a dry surface. Spray it on the oxidation or rust spots so that they are completely covered with liquid. There will be a discoloration, which will be purple in the case of iron rust. Let it work for about 5 minutes. The application time can be extended to 15 minutes, but prevent drying. If necessary, spray more of the product on the oxidation or rust spots in the meantime. After taking effect, absorb the liquid with a tissue or cloth. Before the treated surface becomes dry, always rinse thoroughly with plenty of water until the discolouration has disappeared.
