Before you go to all the trouble of getting all the flammable gas or 
cleaner out of your wing. McMaster Carr has what they call an Air powered 
vacuum gun. You hook it up to your compressor and it blows air through a 
venture to create a vacuum. They have a bunch of them on page 1562 of 
catalog 104. I use their part number 7491T11 in my shop, it is the neatest 
one I think. They cost $84.51. It is a good tool for cleaning up flammable 
solvent soaked gunk. It pulls a very strong vacuum it is rated at 93.15" of 
water (strange unit of measure) at 100psi in. That converts to 3.4psi or 
6.8 inHg of vacuum. You can adjust your air pressure down to get the lower 
vacuum you need to vacuum your wing, and it will regulate at that setting, 
and you don't need to worry about sparks.
