Like I said, you could run it under hot tap water (the foot only) and I'm pretty sure you'd be able to pop the pin out and swap it around. No submerssion of the figure, though I have submerged astro's of all types and they all work fine. The feature doesn't have any metal to it, it's just plastic gears and usually a little hobby grease applied to them... The grease doesn't disappear though, and the figure will dry out.
