I use it, but don't know what makes it do what it does. As good as it works I don't have a problem going to lowes to buy some.
Look up Bio Klean(spell) Scott Wax uses it with damn good results. Type that in the search box and see if you can find some of his posts, or maybe he'll chime in. That gets shipped, as far as I know. I haven't seen that in stores.
Okay its spelt Bio Kleen and There was a post a while back that he explained how to use it but I can't find it right now.
Try this link, it has an MPV that he did that came out pretty damn good with BK.
