Some place in the forum is a link to metal polish that will polish the exhaust and remove the heat stains. Probably in an older how to clean the bike thread.
The fridge cleaner might work or it may be too mild to really polish the exhaust.
You're thinking of bar keeper's friend.

Works a treat, but is harsh. I wouldn't use it unless you're experiencing some discoloration.
