4. Stainless steel conservation
Stainless steel is a popular metal for appliances these days. Many kitchen appliances, both large and small, are made with stainless steel. Pots and pans and eating utensils are also made with stainless steel. One advantage of stainless steel is that is very resistant to rusting. But it can get rust stains from transference of rusty objects. You can keep stainless steel rust-free by following a few simple steps.
Clean frequently with a cleaner and water. Any cleaner that is safe for glass is usually safe for stainless steel.
Scrub off all rust from these objects with a scrubbing pad or steel wood pad. This means getting rid of rust from pots and pans before putting them into a stainless steel sink or on top of a stainless steel stove.
Put a rubber mat at the bottom of the stainless steel sink before placing rusted pots and pans (such as cast iron cookware) in the sink.
Apply a thin layer of lubricant (such as mineral oil) to the surface of the stainless steel. This prevents rust from forming.
Inspect equipment frequently, if you notice discoloration, tarnish or water stains, increase the frequency of your fresh water rinses to reduce accumulated chemicals
