Re: CLR can it clean your rig?
I just used CLR in a squirt bottle on mine, I could see rust all over the purge valve once the bearing was removed, and I could see it start to form in the hose port. Squirted some in there, shook it around a few times, let it sit for about 30-45 seconds and rinsed it out with piping hot water. Didn't smell any CLR or anything, and it virtually removed any rust stains I could see within seconds. I'm going to let it dry overnight and then wash it again with hot water tomorrow before work so I can smoke afterwards.
