M,

Well, compresssed air can be used, but be cautious. Compressed air can be
like teflon tape on plumbing, works great if properly used, can clog the
crap out of things if improperly used. Air can damage things or pack dirt
into impossible to clean areas. Don't even think about it if the compressor
isn't filtered, too much water. If the variac needs internal cleaning, I
would take it apart and manually clean it with a brush and rags, making sure
not to leave any fibers/bristles behind. If you have to use a "rust buster"
on the movement, make sure to get it all off, as it will cut and degrade any
lubricant you use.
