I use one of the quick links... just unsnap it, throw it in an empty Fruitwater bottle 1/4 full of solvent, let it sit a little while, shake, shake, shake, pull out chain, run (old) toothbrush over it, put it in again, shake, shake, shake, wipe down with cloth (old dish cloth? DGF's new dish cloth? Who knows?!) and let the solvent evaporate, then lube your way to happiness. ...oh, and use that brush and solvent on your filthy, filthy drivetrain, too.
