I'm worried that the chain on my good road bike has gotten some grit inside the rollers - well, more than what would be typical. I know that brush-based chain cleaners are no good here, as they only force more grit into the innards of the chain. Is a solvent bath (soaking the chain in mineral spirits, shaking it up, pulling out and letting dry before re-installing and re-lubing) useful to get grit out of the inside of the chain, or does it still only clean the outside mostly?
The chain hasn't lengthened at all yet, so I'd like to catch this before the chain gets damaged more quickly than it should.
I realize that chain stuff has been discussed often here, but I've not seen this specific question yet.
Edit: thanks, mods.
