The Rupes M501 Multi-Purpose Degreaser is a concentrated cleaner that Rupes formulated to be safe for virtually any surface in or outside your auto. Dilute between 1:5 and 1:20 depending on severity of stain and robustness of the material. Rupes Multi-Purpose Degreaser replaces the need for up to 10 different cleaners, all in one. This Rupes Multi-Purpose Degreaser is considered a concentrate and should never be used full strength. For that reason we would encourage you to pick up a couple of our 36 Ounce Detail Bottles and label them for each application recommend for use: engine cleaner, leather cleaner and others areas.
