Quoted from clempo:I used the wall paper tray with a sheet of plastic over it to reduce evaporation.
Make sure the leg is fully immersed, otherwise you will get a demarcation line.
I tried to do 4 legs at once and I regretted it.
You are better soaking 2 legs at a time.
Same.
I built a PVC tube but stupidly went with a 3" diameter and can only fit 2 legs at once. Worse - I've had some lock down receivers that won't fit at all. Wallpaper tray worked great. Between the tube, the tray and a plastic bin for odds and ends - everything gets it's turn in the evaporust bath.
