Well it happend, an older all stainless steel Savage rifle I received had little dark spots around the bolt and in some other places. The rifle must have been stored in a damp enviroment for some time.

I notice that cleaning with No.9 did not remove some of the spots I thought unbernt rifle powder. After closer exam. the metal was pitted very shallow in the dark spots.

I hope most can be polished out. What is best to use?

Thanks
