I don't think that would be a problem.  The stuff is inert and somewhat
volatile (somewhere around the volatility of water), so it will
evaporate eventually.  It leaves no residue.  Just don't spill it on the
floor or you'll have your own private slip'n'slide right there in your shop.

I've even used the stuff to recover data from those dreadful 5.25"
Wabash floppies.
