What are ways to remove chrome plating?

As the title says. I am looking to remove the chrome from a number of parts and pieces. Advice?

A safe way is to try household bleach.. use bucket and cover for a full day or so... tooth brush to finish off....

Take them to a plating shop. They'll be able to do it with less hassle. Let them know what you think the metal underneath is, because it matters.

I thought it was ammonia that removed chrome, and only the chrome that has a copper substrate?

There are several chemicals that can be use but if it is true Chrome (Cr) disposal is an issue. Bleach, Ammonia, Caustic Lye (Sodium Hydroxide), Muriatic (Sulfuric Acid), and even brake fluid. Media Blasting is another method. You really need to know what the base metal is to pick the correct method and what you want to do to it next. As Sniperfan said it is best to take to a plating shop, they'll know the best method given the type of "Chrome" and base metal and will know how to properly dispose of the leftovers. Hell they can even do reverse plating.

Yes a waste plate (anode or cathode). In plating you are just moving metal ions from a source to a destination. Reverse plating is at its simplest is just reversing the plating process and moving Cr ions away from your material to another material in a solution.
