P&S Off Road Mud Buster General Purpose Cleaner takes a unique approach to handling generally hard to clean contaminants and areas. Where most other "heavy-duty" cleaners use harsh chemicals to accomplish this, P&S Off Road Mud Buster General Purpose Cleaner instead creates a dense foam so the safer cleaners in its formula have a longer time to work at cleaning the surface! Without the use of harsh chemicals, P&S Off Road Mud Buster General Purpose Cleaner is perfectly safe to use on most exterior surfaces like your wheels, tires, undercarriage, wheel wells, and even the frame! Since P&S Off Road Mud Buster General Purpose Cleaner is doing most of the cleaning on its own, it requires much less agitation and effort on your end! And if all that wasn't enough, P&S Off Road Mud Buster General Purpose Cleaner also leaves behind corrosion inhibitors to prevent future contaminants from damaging the surface!
