Omniclean is the perfect preparation for painting all different types of surfaces as it removes surface oils, waxes and residue that could interfere with paint adhesion.
Omniclean should be diluted with water. 1 part of Omniclean on 10 parts of water is often sufficient for proper cleaning. In case of heavy buildup, 1 part of Omniclean applies to 4 parts of water. Omniclean can be used undiluted in case of very heavy buildup.
