The result of this oxidation is that the stone develops rust and discolouration. Lithofin BERO is specifically formulated to remove these blemishes. Lithofin BERO chemically changes the rust particles, thereby removing rust discolouration regardless of whether it is a result of the iron in the stone or of environmental influences. Cement residues and similar dirt are also removed.
