Clean & Prep may be applied by brush, dip or spray. (When spraying, use as coarse a pattern as possible to avoid inhalation of mist). Allow to soak for several minutes, agitate heavy soil or stains with a stiff broom then rinse thoroughly with water. Repeat application may be necessary if heavy accumulations are present.
Note: Some types of stainless steel, chrome plating, porcelain on steel and polished decorative aluminum may be discolored. Test before using. Do not use on magnesium or zinc (galvanized). Plastic or polyethylene sprayers and buckets are recommended for application. Depending on the type of stain or soil, Clean & Prep may be used full strength or diluted up to 1:4 with water. Allow to dry completely before staining or sealing.
