Specialist calcium glaze remover. Formulated to meet the problem of calcium build-up on rollers, blankets and impression cylinders. Calcium residue may often be visible as deposits on the rubber or metal surface, but it is sometimes hard to see while still causing transfer problems like stripping. The build-up generally comes from the increased use of calcium carbonate in alkaline papers and can be very difficult to remove. Varn Calcium Eliminator uses sound chemical principles to quickly remove all residue without the need for severe scrubbing.
