I think they are great. I run through the cleaning process about three times, maybe four, for each cleaning. I just use 409 or something similar as a solvent and rinse thoroughly with water and repeat. I dry it thoroughly the las time around and then oil. I attempt to wipe the chain after oiling as though trying to remove all the oil. Seems to leave behind the perfect amount of lubricant on the inside of the links. Oh yeah, I do this perhaps every 4 or 5 weeks when washing the bike.
