I use brake cleaner liberally, particularly in the weep hole in the barrel rib and other spots oil can hide.

I can think of two possibilites besides the residue: 1) You may be running your swab dry or you may be swabing back and forth. Laurel Mtn. is usually very forgiving, but I also know the back and forth swabing will leave the barrels "streaky"...learned the hard way! 2) Leave it on longer with a light and pan of water if you do not have a humidity box or hang it the shower stall with a pan of water and light.

Good luck!
