How to Remove Chrome from Metal Objects: Chemical, Mechanical and Homemade Methods. This video provides various methods to remove chrome plating from different types of materials. Method 1 involves using specialized machinery, such as an abrasive blaster or an ultrasonic cleaner. Abrasive blasting can remove chrome finish, but it produces toxic airborne dust and sediment, requiring appropriate protection. Ultrasonic cleaners use sound waves and cleaning solutions to remove chrome from delicate items like jewelry. Method 2 involves chemical solutions like hydrochloric acid or sodium hydroxide, which can strip chrome from metal objects. Hydrochloric acid requires a solution of 30-40% concentration and submerging the object until the chrome comes off. Sodium hydroxide should only be used on ferrous metals and carbon steel, and the object should soak in the solution for some time. Finally, reverse electroplating is a very effective but extremely dangerous method that involves using a live electric current and produces toxic, carcinogenic chemicals. It's best to leave it to professionals.
