I've tried loads, and have run waxed chains for a few years topped up with either Silca drip lubes, Squirt or Smoove, all of which were pretty clean. None are particularly good in the wet unless topped up frequently.
I tried a free sample of Revolubes stuff recently and much to my surprise as a massive skeptic, after three applications to a prepped chain it's still looking clean as a whistle, not squeaking or dry and not rusty, the bike's done a load of off-road miles and been pressure washed twice (yes I know, I'll just replace the bearings
).
Only downside so far: I was impressed enough to order a proper bottle and ten days later it's not arrived, and the sprog says it must be full of toxic badness to work that well.
