A powder coat finish needs little maintenance, but not none. Dirt, salt and pollutants that stay on the surface end up dulling the finish. The good news: powder manufacturers agree on a simple method.
The three-step method
The maintenance guide from AkzoNobel Interpon recommends lukewarm water, a mild, non-abrasive detergent with a pH of 5 to 8, and a soft cloth, a sponge or a soft brush. Then rinse thoroughly with clean water. That is all. The manufacturer TIGER Drylac adds two precautions: do not clean a surface warmer than 25 °C, and do not use a steam jet.
How often?
At least once a year, TIGER says; AkzoNobel gives the same 12-month interval for a standard polyester. Both guides call for more frequent cleaning in a harsh environment, such as the seaside or an industrial area. They do not mention road salt, but the principle is the same: do not let a corrosive deposit sit on the finish. For wheels or chassis parts that are driven in winter in Quebec, a regular rinse during the season and a good wash in the spring seem to us to be a minimum.
What to avoid
Both guides advise against abrasive cleaners, polishing compounds and strong solvents, such as acetone and other ketones, esters and chlorinated solvents. For a stubborn stain, test the product first on an area that is not very visible. Manufacturers do not all agree on milder solvents: when in doubt, stick to soapy water. For architectural aluminum, FGIA published a new edition of its cleaning guide in 2025.
What if the finish is damaged?
A chip that exposes bare metal should be touched up quickly, with a liquid paint of the same colour, to keep corrosion from setting in under the finish. For more extensive damage, the part gets stripped and recoated. Send us a photo: we will tell you what is appropriate in the quote.
In summary
- Lukewarm water, mild detergent with a pH of 5 to 8, soft cloth, thorough rinse.
- At least once a year; more often for anything driven in salt.
- No abrasives, no strong solvents, no steam, no hot surfaces.
- Touch up without delay any chip that exposes the metal.
