If removing the chain I drop it into a glass jar of what ever I have around like, Charcoal Lighter Fluid, Diesel, Paint Thinner, Gasoline, Denatured Alcohol, Bourbon, Cyclohexane, TET, Barsol, or, or, or... No really its Charcoal Lighter Fluid usually.
Then after all the gunk outta it a soaking in ATF Automatic Transmission Fluid. And a wipe off...
Then I mount the chain and hit it with some 30 wt motor oil. And wipe off...
If not removing the chain then I just liberally lubricate it with ATF and keep running the chain through a rage till its clean. I then lube with 30wt motor oil. I do this often cause the light gravelly roads I ride kick up allot of dirt.
