I've been using the stuff like Frank's red hot and put everything in it.

Stainless, chrome, rotors, calipers, suspension, driveshafts, hood hinges, rubber mounts, aluminum parts, die cast, brake cables, hollow hard lines and it's flat out excellent for cleaning seats belts without ever disturbing the ink on the dated tags or printed labels. Just be sure to rinse parts with soap and water right when they come out and blow them off with an air hose or give them a good wipe down.

I've used about 20 gallons of it in the past couple years and I'm ready for a new 5 gallon pail real soon. I buy it from Fastenal and have all kinds of different containers that I use it in. Get your hands on a long shallow goat feeding trough or window planters for those long items you want to soak. As above, you can get creative with 3" or 4" tubing with end caps glued on.
