Chrome plating removal.

Purple Power does the trick.

If you are going to be Alclading (or other NMF), you can just prime and paint it, without removing the chrome (actually usually a vapor coated aluminum).  Use a good metal primer, then the black undercoat, then the Alclad or metalizer.

Regular Easy Off oven cleaner, yellow can. Strips it in minutes. Then rinse with water.

Thanks for the suggestions folks.

Soaking it in a mixture of salt and vinegar will also disolve the chrome.

I've had some success with testors ELO. It did seem to make the plastic a bit brittle though.  Destroyed my 1:200 dc3.  

I've used easy off to remove paint, didnt know it worked on chrome.

Ammonia / water solution works fine and is less harsh on you and your pets.

I use fume free Easy Off oven cleaner. For small parts or those still on pieces of sprue, I put them in a zip lock bag, spray liberally and seal overnight. Scrub with an old toothbrush when done, don't get on your fingers since it is caustic.

What is best for removing chrome plating from plastic parts?

SuperClean.  I used it to remove the chrome from the plated sprues in the Monogram Red Baron hot rod.  It removed the chrome in two minutes.  It simply dissolved into the solution.

I used Clorox and works super fast. I also heard that Simple Green works too but takes longer. Clorox takes but a few minutes then rinse in water.

If I need to remove from the back side of chrome wheels, I'll put a little bit in one of those disposable Glad type containers and set the wheel face up inside. Put the lid on overnight. I'll also use this if I need to soak a bunch of individual parts.
