Tupperware is your friend. You would not believe all the shapes and sizes that stuff comes in. Works well as a soaking tube. Or just get a piece of 3 inch PVC with a cap, cut it to the length you want and soak away.
This, use a length of 3" PVC pipe and put a cap on it. You could soak pretty much everything except the very top that way, then just flip it over and soak the end in a smaller container.
