Dilute one dose of Star Brite Vinyl Concentrated Cleaner/Shampoo with ten doses of water in a bucket (for white vinyl surfaces, less diluted doses are needed). For lightly soiled vinyl surfaces, apply the product with a clean rag or sponge and scrub the surface. Rinse or scrub the surface with a clean, damp rag before the product dries. For deeply encrusted dirt, soak a stiff nylon brush in the product and apply it to the vinyl, scrubbing. Work in small areas to keep the product moist. Rinse or wipe the treated area with a clean, damp rag before the soiled product dries on the surface. Continue cleaning until the entire area to be treated is clean. Let dry and then apply Star Brite Vinyl Brite to protect and preserve the vinyl surface. Do not pour the product on colored surfaces. Avoid leaving the product in freezing conditions.
