What is the best way to maintain my powder-coated panels?
For normal maintenance you can use soft cloth wringed out in clean water, possibly added with a neutral cleanser. Immediately to be dried with a dry cloth. Do not clean the panels in full sunshine because it can cause stains. Grease stains and adhesive residues can be cleaned with a neutral cleanser.
Never use: aceton, strong alcoholic agents, acids or alkaline solutions that contain ether, glycolether or hydrocarbon. When you are not entirely sure of the compound of a certain product, it would be best to test the product on a less visible surface.
