The easiest way I have found to clean a lock is to do it with boiling water. I will put the teakettle on the stove, get the
water hot, then pour it over the pan, the bottom of the frizzen and over the cock.....it comes out clean...immediately.
Since it is hot, it evaporates immediately. I then spray it with WD40, wipe it off and re-oil some of the bearing surfaces,
done. I only do this when I am at home, if I'm still out hunting for several days, I would merely wipe out the pan and othere surfaces that I could get at easily and go on............Don
