Powder coating is a free flowing powder material applied to metal surfaces and baked under heat to form an ultrahard finish that’s more resistant to dents, corrosion, and chipping than traditional wet paint; nonetheless it must still be cleaned regularly to preserve its effectiveness.
If your powder coated products are showing signs of wear, begin by giving them a gentle soap and water solution clean. Avoid using harsh cleaners that could damage their finish.
1. Soap and water
Powder coating may be resistant to things like rust, corrosion and fading; however, that does not preclude it from becoming stained by oil, grease and dirt. Harsh cleaners or solvents could damage its protective qualities while mild soap and water should suffice when cleaning it up.
Simply use a brush or sponge to gently clean off any loose dirt or grime from surfaces. If something stubborn remains, an abrasive cleaner might prove helpful; be sure to always use mild detergent and rinse the surface with clean, filtered water afterwards.
Cleaning frequency will depend on both its environment and use; for instance, powder coated steel fences near oceanfront locations require more frequent maintenance to clear away salt residue; other products like appliances or outdoor furniture generally only require monthly cleans to remain effective.
2. Mild abrasive cleaner
Powder coating can protect against scratches and nicks, but isn’t entirely resistant to all impacts. Stains may tarnish its finish; to preserve it for as long as possible it’s important that they’re removed quickly and thoroughly.
There are various mild abrasive cleaners that can be used to effectively clean powder coat without harming its surface. Before choosing one of these solutions, read its label carefully and follow any applicable instructions for use.
These cleaners typically contain small particles of abrasive material such as nylon sponge, rotten stone or whiting to provide gentle yet effective cleaning action. Some also include disinfectants to help decrease bacteria numbers on surfaces where dirt accumulation has taken place.
If the above solutions do not do the trick, WD-40, which is a petroleum-based solvent that will dissolve stains quickly, may help. Just ensure you test a small area first to make sure it won’t damage the powder coat surface.

WD-40 is a spray can lubricant and solvent that can be used for various cleaning applications, from dissolving rust to tight spaces lubrication and even fingerprint removal from stainless steel surfaces.
4. Sanding
Powder coating may be more resistant to damage and stains than traditional paint, but it still needs to be regularly maintained in order to remain undamaged and spotless. When exposed to harsh environmental elements, regular cleaning using mild soap-based solutions should be conducted as harsher chemicals or abrasives can damage the finish and compromise its appearance.
When faced with stubborn stains, using medium-grade sandpaper to gently scrub can help. Before proceeding with this method, always test an inconspicuous area first in order to make sure it won’t cause damage to the powder coating.
Maintaining clean powder coated metal products is not only for aesthetic reasons; it is essential for their long lifespan as well.
