Buy a turkey roasting pan and flatten it on one side to snug it up to the tire. Put cardboard between the chain and wheel. I use a paint brush cut down and kerosene. I dry the chain with compressed air and wipe it with a rag. Le it dry a bit then Bel-ray lube inside and out. Let it sit for a bit then wipe it down again. Also I do remove the chain guard.
It's best when the chain is warm from a ride. Oh yeah-important-when you wipe the chain-make sure it's going away from the sprocket!
