Pickle & Oil

Pickle & Oil is a metal surface treatment used to remove impurities, such as stains, rust, or scale from ferrous metals. Bundles are broken and parts separated and then dipped in a solution which contains strong acids used to remove the surface impurities. It is commonly used to descale or clean steel in various steel making processes. After pickling, a light water soluble rust preventative is applied to slow the rate of rust.
