SMR-830 is a water-based pre-cleaner that removes road grime, silicone, grease and wax from surfaces. It leaves no residue when used properly and has a low VOC formula making it compliant with regulations. The pre-cleaner can be sprayed directly onto cool surfaces or applied with a cloth. It must remain wet on the surface to penetrate and dissolve contaminants before being wiped off with a clean, dry cloth. Proper use of the pre-cleaner is recommended before repair work to prevent contaminants from being forced into surfaces.
