After years of use in commercial kitchens and businesses, Suprimo is now also available for households. It cleans metal, concrete, ceramic, stone, glass, wood and plastic (garden chairs). Be careful with aluminum (think of cooking burners). Use Suprimo Alu-Clean to prevent discoloration. Contains: Non-ionic surfactants Tetrasodium ethylene diamine tetraacetate solution. I-methoxypropan-2-ol Potassium hydroxide Alcohol ethoxylate 6 eo Suprimo cleans even heavily soiled surfaces. Stubborn dirt such as burnt-on grease will disappear quickly if the (preferably heated) surface has been sprayed 2 or 3 times with Suprimo. Paintwork, walls, doors and windows should be cleaned with a diluted solution (a generous splash on half a bucket of water).
