Stainless steel is an iron alloy that also combines chrome, molybdenum and nickel making it highly resistant to corrosion and staining. By powdercoating stainless steel, increases it's resistance to corrosion to a level comparable to aluminium.
Much like Aluminium, Powdercoated Stainless Steel is easy to clean with clear water and any pH-neutral fluid detergent. Any stubborn stains can be removed with a standard Aluminium Cleaner. If necessary, use a SOFT brush to remove the dirt from the pores, a hard wire brush will leave the surface scratched. To take preemptive steps against dirt adhesion you can apply a Metal Protector that includes Teflon® this applies an invisible protective film that stops dirt sticking to the metalwork.
