Just recently while trying to adjust an M1 chinstrap, I used a pencil to fit under the loop and pull the tightly bound canvas out... And out of curiosity, I decided I didnt quite like the green that was on the brass, so, using what I had in hand, I took the pencil eraser to it. I cant show before, but, it worked very well with what seems like no damage to the black coating on the brass and brass itself... Just thought I'd share this one.

Good technique!

Erasers are mildly abrasive, and most oxidation/discoloration/tarnish on brass will not respond to chemical treatments after a certain stage of accretion/deposition.

I just recently finished cleaning up a 1940s brass bell that had been in the family a long time, covered with layers of house paint and tarnish.

I tried everything, starting with the most mild steps/materials, and then gradually working my way up to the more aggressive (i.e. abrasive) ones. In the end, I had to use my palm sander with increasingly less harsh paper, then the same approach using increasingly less harsh steel wool, and finally some actual Brasso.

The whole project took me about 30 hours.
