Whelp, I found a 2 quart crock-pot for $5.13 at my local thrift shop. Used the Silca system: new Shimano chain de-greased with their chain cleaner, rinsed with water, dried for a while, then immersed in their ‘secret blend’ wax (has tungsten disulfide in it, among other things) at 200 degrees Fahrenheit for about an hour with occasional swishing, cooled, and now drying on a sheet of plastic. Cleaned the rest of the drivetrain. First ride with a waxed chain tomorrow, woo-hoo!
