Chrome plating is the process of attaching a thin layer of chrome onto another metal. One of the main reasons for chrome plating is to give an object a lustrous silver finish. Furniture, decorative objects, small appliances and jewellery are just some of the objects that use chrome plating. As a metal, however, the chrome can form rust. This mostly occurs when the rustproof coating on the chrome wears off and then the chrome plating gets exposed to moisture or water. Removing rust from chrome plating is a delicate procedure because you don't want to damage or remove the plating.
Scrub off the rust gently with a fine steel wool pad. Fine steel wool is effective in scrubbing away surface rust without damaging the underlying material reports Society of American Silversmith website.
Make a paste in a bowl of two parts lime juice and one part salt. This is a non-toxic and gentle way to remove rust. Lime juice has citric acid that helps in removing rust and the tiny grains of salt offer a scrubbing action on the rust.
Apply the paste to the chrome plating with a paper towel. Use paste only on the rusted areas.
Leave the paste on the chrome plating for two to three hours for best results.
Wet a sponge and wipe away the paste completely.
Dry the chrome with a clean cloth or paper towel.
Repeat Steps 2 through 5 if rust remains on the chrome plating.
