To clean rust out of a composite wood deck, you just need an effective way to get the iron oxide residue off its surface. The cleaning agent you use should depend on the severity of the stain.

Without getting too technical, stainless steel contains chromium—which, when exposed to oxygen, forms a thin, invisible layer (chromium oxide) that coats the entire surface of the appliance ...

Next, use a rust inhibitor or converter to impede the tin worm’s progress. Your steel may look shiny after knocking the visible rust off, but there’s still some iron oxide there.

Despite its name, stainless steel can rust. The material is actually an iron alloy made of several metals, including chromium, that forms a chromium-oxide layer on its surface.

Rust and Stainless Steel Rust is the result of iron reacting with oxygen in air or water to form iron oxide. The corrosive process, known as oxidation, weakens the underlying material.
