so you somehow are able to whipe the inside of a chain? whiping the outside doesn't do much other than take off excess so dirt doesn't build up

the problem is you get all the grime inside the links, and this rubs against the cog and chainring, this is where you get the grinding, unless you are putting the triflow on in massive amounts at a decent pressure i don't think you are washing any of this away ... you need some kind of wash to do this, for me i use a bio cleaner, whip down, then lube ... seems like cleaner would be better at cleaning than more lube
