Lithofin Rust EX Non Acidic Rust Stain Remover - 500ml

Removes rust stains and residues of metal oxide from natural stone and tiles caused by metal garden furniture, iron containing fertilizers, leaking heating systems, etc.  Suitable for ceramics, concrete and all acid sensitive natural stones, including limestone and marble. Acid Free.

Properties:
The reactive compounds work on the rust and transform it into water soluble particles. The reaction becomes visible through a purple discolouration. The resulting particles can be rinsed off with water. Lithofin Rust-EX does not change the appearance of the surface and can therefore be used on single stains.

Field of Use:
For removing all kinds of rust stains. Causes for these stains may be iron containing fertilizers, metall garden furniture, leaking heating systems, etc.

Surfaces: suitable for all ceramic surfaces, marble, limestone, granite, gneiss, concrete and artificial stone.

Directions for Use:
Generously apply undiluted product to the dry surface and distribute with a brush. A purple discolouration shows the start of the reaction. Allow to work for about 5 minutes, 10 minutes max! Do not allow product to dry. After working time, add water and a splash of Lithofin MN Power-Clean (or diluted dish liquid), brush and rinse off with plenty of water.

Important: working time must not exceed 10 minutes. Repeat procedure in case of unsatisfactory results.
Ferrous natural stones or stones containing as well as coloured concrete stones may change colour after treatment with Lithofin Rust-EX.
