Tips to get chain completely clean on-bike?
I have a Filzer CC3 chain scrubber which from what I read online is supposed to be a good one. I take great pains to get the cassette, jockey wheels and chainring clean so there's no contamination from them and scrub and rinse the chain multiple times so it's sparking. When you run your fingers or a rag down it, nothing comes off, at this point the chain and all gear teeth seem white-glove clean.
Yet when I squirt on lube and wipe the chain, I'm getting residue on the wipe-down towel. What I'm guessing is happening is when the lube is applied, gunk is being irrigated out from under the rollers, where the scrubber brushes don't reach.
Any tips on getting to that under-roller gunk without taking the chain off the bike and sloshing it around in solvent/degreaser?

But if you must get it spotless, it is probably quicker and easier to whip the chain off, and the cassette, and get at them in a bowl using your degreaser/cleaner of choice. With the chain off and rear wheel out, the derailleur is also much easier to get at.

However, strip it only occasionally and re-lube properly.
If you wax your chain you never have to clean it.
Or you could just brush the white spirit along the return run and catch it in washing-up bowl, then as per above.
Clean chain & low friction....
Bit censored for winter bike though
I thought washing up liquid had salt in it?

Here’s the science bit.

Even if it did have salt in, I'm rinsing it straight away in clean water anyway so wouldn't matter anyway.
If you wish to pursue the holy grail of a clinically clean chain, the only realistic way of achieveing it is to use an ultrasonic parts cleaner with several changes of solvent / degreaser. And then I think to get the lube back in to the internals, you'd need to marinate the now sparkly chain in your chosen oil / wax / whatever in the ultrasonic bath. Which all sounds quite a faff, but if that's what floats your boat, go ahead.
I used to try to get chains clean by taking them off and shaking in successive lots of white spirit or paraffin, but I CBA with that these days. Now I leave them on the bike, wipe down with a rag soaked in spirit every week or so, relube sparingly, then wipe down thoroughly and repeatedly with a clean rag. I accept it's not perfect, but it's good enough to avoid premature wear of the drivetrain, and 9 / 10 speed chains are cheap enough.
