I'm running an o-ring chain and my usual routine is to drench it with simple green prior to washing and scrub it with a soft brush. Then I start the bike and put it on a center stand to let the wheel spin and get rid of most of the water. Then I WD-40 the holy heck out of it to remove any remaining water and provide some lube. This has worked pretty well for me, but I'm startin to notice some build up of grime. With a regular chain, I would periodically remove it and clean it with gas or solvent, but I've been told this is a no-no for an o-ring chain as stong solvent will damage the o-rings. Any of ya'll got some suggestions? How do you guys clean your o-ring chains? Thanks in advance.
