Ray! Good to see ya, Bro! Nice set up with the center jack. I like it! You know,, I HAVE USED ONE OF THOSE TRI-SIDED BRUSHES! (sorry,, was yelling there ) So, cool! Like those brushes. Quick in and out, for sure!
its called a grunge brush. they are like 15 bucks for the brush and some tree hugger friendly cleaner. the cleaner is kinda expensive, but it does work pretty well. the one i bought was about 10 yrs ago, so they prolly cost abou 150 bucks now...but they do work efficient and good at cleaning all parts of the chain. lockheart phillips used to sell them. i know they are still available.
