Careful - the effect of the alcohol on the polycarbonate that I mentioned in
my post took months to notice.  Only a small amount of damage was
done with a single application and it took over a hundred applications
before it was obvious to the naked eye.  You'd have to go over the list
of ingredients (if listed) and check whether any one is a candidate
for causing damage.
