you could probably remove the assemblies with the lights attached and do the soap and water rinse trick, did this yesterday with Denny G's light and it worked. I was surprised that the gray went away that easy. After that we heated the lights with a hair drier and let them sit and all the water evaporated. Take the grill off and it will be a lot easier to work with. The grill is easy to remove and speeds the process significantly.

Can I ask how much you paid for these?
I have my original set sitting in a box and was thinking of selling them
