Ok Anne, finally getting around to the "review"...

This stuff works great on parts that get all ganked up over time that you can't get at very well to clean - cassettes, inner chainrings, front derailleur, rear derailluer jockey cogs, hubs... that kind of stuff. I have a SRAM 990 cassette with a cool red spider, that hasn't been visibly red for awhile. After using the D.O.G.G., it's shiny new! I didn't exactly follow directions (go figure) as I hosed it off after letting it set for a couple of minutes.

Good stuff, I'll keep using it and will call the number like you suggested. Thanks for the donation!
