Click the box below to discuss your application with one of our coating scientists. Clean the stainless steel once a week with a nonabrasive cleaner, such as window cleaner or a cream cleanser for glass-topped stoves. The hard part is keeping the rust off without costly component redesign or re manufacture. Contact our Technical Service Team for a free coating consultation. For multiple applications, keep the mixture hot. A chrome oxide layer will then form within the metals preventing further rusting. Highly aggressive rust removal agents and cleaners can etch part surfaces, creating sites for renewed corrosion or damaging surface finish, seal areas or flow paths. Dry the pots and pans after removing rust and after each wash. Use a lint-free towel to remove moisture from the inside and outside of the cookware. This allows the formation of a protective film of chromium oxide which acts as a shield against rust. Here’s the thing: there’s a substantial amount of oxygen in water, which is why exposure to water causes metals like steel to rust. Scrub lingering stains with the toothbrush bristles until you remove rust stains completely. The best part? Depending on the specific alloy, 300 series exposure to aggressive acids can range in durability from a few hours or days to a year or so before failure; not a great model for reliability.
