Lithofin Rust EX is a mildly alkaline cleaner for removing rust stains and residues of metal oxide. It contains reactive compounds that 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 is for removing all kinds of rust stains. Causes for these stains may be iron containing fertilizers, metal garden furniture, leaking heating systems, etc. It does not change the appearance of the surface and can therefore be used on single stains.
Lithofin Rust EX is suitable for all ceramic surfaces, marble, limestone, granite, gneiss, concrete and artificial stone.

Directions for Use:
Generously apply undiluted Lithofin Rust EX 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 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.
Please Note: always try the product in an inconspicuous area prior to use. Avoid contact with metal, varnish, wood, etc. Long working times on polished limestones may cause the surface to become slightly dull. The remaining light discolouration will disappear with time.
