Dip a long bristled brush into your solvent. Slide down the inside of your barrel from breach to muzzle. (This means in the direction the bullet fires out of your gun.)
Change out the bristle for a patch holder. Insert a square, 100% cotton patch into the holder. Slowly slide the patch through the barrel, breach to muzzle, until it is clean.
Add a few drops of gun oil to a new patch and wipe down the outside of the barrel.
Using a new patch, wipe down the inside of your slide.
