One tip from prepping many chains for the first time is to use a 600mL gatorade bottle (or similar) with a wide mouth. Chain goes in with a small amount of your degreaser and subsequently isopropyl alcohol and it makes a really good "aggressive agitation vessel". I keep a dirty bottle for recycling the old degreaser and for the initial rinse, then a clean bottle with fresh degreaser, and a third bottle for isopropyl alcohol.
