I just removed a coat of bad weathering and all the lettering on a lionel scale PS1 boxcar with the super clean product. it left the silver base color untouched. I sprayed on super clean and wrapped it in few sheets of paper towels wet with more of same and to control evaporation wrapped it in a plastic bag. 8 hours later unwanted graphics and weathering came off easily with soft brushing and warm water.
No noxious oven cleaner smells
rubber gloves were needed as with any high power soap
