Perhaps you would have better luck with your question on the Classic Toy Trains forums…
Good luck!
The classic toy forum would likely have more info. But I’m assuming ( yes taking all the responsibilities and reprecussions of assuming ) that Lionel and Marx have or make a ready to use wipe on cleaner. If it’s nickel silver mostly perhaps a standard bright bot of appropirate size may help as well for those in between the chemical cleanings. Hope I’m helping if not as stated try the regular MR or Classic toy sites. You will likley find many more answers. Rob
What in the world does this have to do with classic trains. Let it go people …
