Thanks for the tip. I use a two different sized ultrasonic cleaners for bicycle service and the shallow version will work well for this job. I think if I lay the VP spring side down in the Ultrasonic cleaner and at half full it will just barely touch the top of the inside portion of the VP. The nice thing about the machine is it uses heat, sonic waves, and whichever cleaning solution you choose. In this case I've a 1/2 diluted version of Simple Green's Pro HD cleaner to work very well without being as caustic to a part's finish or rubber pieces. Will give that a go and report back on results.
