Aqueous Rust Inhibitor is a powerful short term corrosion inhibitor designed for the protection of ferrous and cuprous (yellow) alloys. It can be used in wet or dry sand blasting, as well as high pressure water cleaning to prevent rust and corrosion on metal surfaces. After cleaning or machining, parts can also be sprayed or dipped in this solution for added protection. With its complex sodium salts, this inhibitor provides up to 24 hours of corrosion inhibition, although actual protection may vary depending on environmental conditions. Keep your metal surfaces rust-free and in top condition with Aqueous Rust Inhibitor.
