I keep an old Windex spray bottle in the laundry room that's filled 50-50 with Pine Sol & Simple Green for soiled clothes pre-scrubbing. I use that mix for cleaning the outside of the plug with a toothbrush.

I then grab the needle-nose pliars & hold the plug under real hot tap water - blasting both holes of the plug for about one minute. I shoot some of my 50-50 mix in the 209 primer hole & use a pipe cleaner & end of a paper-clip inside that 209 hole.

I then grab a sewing needle that's big enough to enter the small breechplug face hole & make sure that's clear. I then grab some carb cleaner spray with the long red straw-nozzle & shoot-spray carb cleaner in the 209 hole - holding the plug with the pliars.

I then give the plug another real hot water rinse & vigorously shake it dry for a minute. I let it sit on the laundry room shelf overnite - then put it in a clear sandwich baggie & wrap it around the end of the ML ramrod closest to the muzzle in my gunsafe. It stays there until I'm ready to go hunting or to the range.

I install it/grease ittwice when it's time for shooting. The first time I screw it in, it will coat the barrel threads pretty decently. I then uninstall it - give the plug a 2nd coat of CVA Breechplug & Nipple Grease -- then install it for the last time.
