How to Clean Rusted Metal Milk Crates

When iron and steel are exposed to water and oxygen, they begin to rust. Rust is a chemical compound called iron oxide. Iron oxide molecules are larger than the molecules in iron and steel; the larger molecule size results in rust bubbling out from the metal and flaking. There are many petroleum- and wax-based products on the market that prevent rust; zinc primers available in aerosol cans will also prevent metal from rusting. Once you remove the rust from your milk crates, treat them with a rust-prevention product and keep them dry.
