At the bike shops, we use gasoline or parts wash solvent and wash it out and
then blow it out
with shop air. work from the inside to the outside (reverse the direction the
air flowed into
the unit).

You should, it's the best air filter oil out there. It's incredibly sticky
stuff. Which is
what makes it work. Using engine oil and such just doesn't do a good job on a
gauze filter.
The only oil I've ever met that might work is rock drill oil. And it isn't any
cheaper then
filter oil.
