Cleaning rust from muzzle?

[Kleinzeit]

I usually clean the same day I shoot, but a little while back I went out shooting with some friends, got home late, yada yada yada...

I was very disappointed, when I finally got around to cleaning it, to find rust at the top end of the barrel. It seems to be okay inside, but the rusted area ( as you can see) is very close.

Is it okay to use some 0000 wool? Is a brass brush better? Or should I just leave it alone? This is a CZ-75 SP-01.

I already cleaned off as much as I could by soaking it in some Breakfree and going at it with a q-tip.

Use 0000 steel wool, dry.
