Not sure how much a can of Easy Off is in the US, but here its far cheaper to buy a container of Caustic Soda, mix up a batch in a large tub and toss the parts in.
Let 'em sit a day, flip 'em over, and then pull them out after another day. It can take as little as a few hours if you are impatient. Light scrubbing with a toothbrush or similar tool can help (wear good rubber gloves and eye protection, and in a well ventilated space!)
Done numerous dash parts, dome light bezels and horn pad trims. Removes the old vaccum deposition "chrome" coatings too.
Same proecess can be used to remove old anodizing.
