I would just not worry too much about it. I use the foam bore cleaner which has a solvent that goes after the jacket material, and the brushes too. I probably get three or four cleanings from a brush.
Why worry about a $2.00 bore brush? Think about it: Every time you go to the range, you shoot off many times that worth of ammo.
