Cleanning Frosted finish

I  have found that pieces with a satin or frosted finish that have
been laying around for a while and are tarnished are very hard to
clean with the standard methods of removing tarnish i.e. polishing
cloths or mild silver cleaners such as Haggerty's.   Any
suggestions for a better way to clean pieces with a frosted finish
would be appreciated. 

Hello Grace, I too work with the 3m wheels and the best cleaner by
far is concentrated Simple Green. Available at Costco, Vons… Soap
in concentrate 5 min then scrub with soft toothbrush.
