Cleaning after 50+ black powder shells

[Mike of the Mountain]

Whether I shoot my 12g black powder shells in my Parkers or Foxes, the clean up is brutal. 50+ bp shells makes a mess of my barrels. I shoot a few smokeless rounds through them and it clears SOME residue out. I use hot water and soap, but I hate having to put a fine set of vintage barrels into water. Always afraid there will be some leakage into the ribs or the extractors won't get cleaned/lubed properly and will rust. Anyone have a better way to clean the barrels? I heard some guys use a swab with windex. Does that work? After shooting the BP Event at the Spring Southern, I cleaned my barrels in the hotel bathtub!!! Ya should have seen that crime scene!!!! I had to get housekeeping to scrub the tub. Wound up looking brand new, but it looked like I dumped drain oil into the tub!!!! I thought it was funny. Wound up giving the housekeeper a nice tip.
