I think it could be done, it's not water, but I don't see how that would ever be necessary with a VV, since there are no moving parts, and everything is sealed up pretty well. I will say that I can disassemble a metal reo and do pretty much everything except take off the tube. (only because If I take it off, I don't have a new one to put on) I found that if you use one for about 6 months and never clean it, it will gum up, especially if you just keep adding noalox and not cleaning it. I got ahold of one I sold a friend the other day and it was so bad the button wouldn't move. Even some kind of gunk under the spring. Just unscrew everything and put it back together. It's easy peasey.
