Nothing beats an onion sack except they don’t make onion sacks small enough for pocket carry.

A few quick swings around your head will remove any residual moisture by centrifugal force.
Dip your gun, sack and all, into a can of burnet cylinder oil and follow the instructions given for cleaning your gun.
