I do the same as TT, let dry then a few drops of oil. Takes 5 minutes at most and if you keep up with it the chain never gets a chance to get truly filthy. If I slack or grime builds up I'll remove the chain and let it soak while I clean the cog/chainring. I used to scrub the chain on the bike with a tooth brush what a mess, the missing link on the 710sl makes it sooo easy
