Van is correct but you don't have to go to a solvent, just use a detergent. Ammonia causes stress corrosion cracking of brass so if you get ammonia based bore cleaner on your brass wash it off.
Final wipe or initial cleaning ?. Media tumbler works or wash with Borax and Hot water or combo of TSP also works well . Lacquer or Acetone works well for final wipe .
Ever try to remove tree sap off a chain saw blade ?. Gum resin is one of the most difficult materials to remove from metal. Borax will do wonders !!. Lacquer & acetone do little .
Also for heavy weather corrosion on brass a MILD Acid solution works very well and quickly !. Be sure to neutralize ( baking soda and water bath )then rinse well !!!. Tooth paste also works or automatic commercial dish washing solution . There are numerous good safe brass cleaners in your home !...

Thanks
If you just want to degrease brass buy some 90% isopropyl alcohol. It is cheaper and safer than acetone and removes sizing lube well, plus it evaporates quickly.
