As far as the shooter lane goes, I would like to clean it up further..In my boredom I've been looking at some resto photos the Treasure Cove has done.  It would seem that this is an area that on all their machines are always absolutely spotless.  I've tried the usual suspects - nifty on rag, magic eraser with shellite etc..but there is some marks which I cannot get off?

Any ideas would be appreciated too?
