Once applied, powder coating needs to be properly cared for, just like any paint. Usually, a basic cleaning schedule a few times a year will suffice.
Some basic tips:
Avoid excessive contact. Approach with an attitude of “less is better!”
Avoid harsh, abrasive cleaners such as steel wool and scourers. Treat powder coating as you would your car paint.
Avoid solvents where possible, When a solvent is absolutely necessary to remove materials from the surface, such as adhesives, the weakest possible solvent should be used (e.g. methylated spirits, white spirits or isopropyl alcohol). A small and unobtrusive area should be tested prior to attempting to use solvents on significant surfaces. After removal of the surface contaminant, the solvent should be dried from the film, and the area that has been wiped with solvent should be washed with a solution of mild liquid detergent and then rinsed with clean water to ensure complete removal of any solvent residues. Under no circumstances should strong solvents be used. Examples of inappropriate chemicals for cleaning or for any contact with powder coating are gasoline, kerosene, MEK, xylene, caustic cleaners like kitchen and bathroom detergents, and paint thinners. Always flush metal that has been exposed to cleaners with copious amounts of fresh, clean water.
When a scratch is discovered, it should be addressed immediately. If bare metal is exposed, it should be lightly sanded with a 180 grit or finer sandpaper to remove any corrosion that may be present. Then the sanded area should have all sanding debris removed with either a clean brush or compressed air. The surface can then be touched up with a liquid paint; we recommend a high quality architectural or automotive grade paint, enamels or two part urethane.. Two or three coats of paint are usually required to achieve adequate coverage. For larger areas a liquid primer is recommended.
