After 50 years, my simplest solution is 1) use/add a quick link like a Wipperman that can be easily removed and replaced by hand; 2) remove a dirty chain, immerse in naptha (a few $ a gallon, cheap Coleman fuel) in a small Gatorade bottle, agitate, soak for a few minutes to overnight; 3) Remove, wipe clean with rag or old not too fuzzy cloth, air dry; 4)Return to bike, after separately washing rear cogs and chainrings if required; 5) apply lube sparingly, Squirt being a good waxy product. Wipe off excess.
My best choice is to actually use paraffin, in a shallow pan, melting just enough to liquefy with the dry clean chain immersed. Stir a few times with a hemostat or pliers, pull slowly up as wax runs off, then lay it onto a newspaper and agitate to remove excess- careful, as it is a hot chain! Wipe more as temp drops, then hang to cool. Then, just reinstall with no further oil, and ride for a couple minutes to loosen the wax stiffness. Lasts several times as long as the best oils, much quieter, attracts no dirt or dust, can be wiped clean; extend intervals with a wax compatible lube (Squirt), then repeat. Wax is easier to clean off, and reapply, the heat being the only crux, as hot wax can spill and burn skin badly.
