Care and Maintenance While most powder coat ﬁnishes are tougher and much more ﬂexible than conventional solvent based paints, they are about the same hardness as automotive paint, so they will scratch. To clean a powder coated surface, use the same care and methods you would use to clean your car. Gently wash with a clean, soft cloth and a mild detergent followed by a clear water rinse. Additionally, certain solvents can harm powder coat ﬁnishes. Avoid contact with nail polish remover, paint or lacquer thinner, motor oils, transmission and brake ﬂuids or parts cleaning ﬂuids. If any of these should contact the powder coated surface, immediately wipe the area with a soft, clean cloth, and wash as described above.
