Just on a whim, I tried one of my wifes forced air dog driers to blow out all little bits of cut wire, solder blobules, cleaner .....the crap that you need to get out of the radio before you apply power. I had used a air kompressor but it was a pain. it would always kick on and startle you in the middle of some operation scaring you to death.
these dog dryers have a gentle heater built in which you can select or turn off. basically a big azz cage blower wih a 10 ft hose. I like this solution far better than any other I've tried. Heres' a link.
In the doggie trade they are called force dryers. Dri Eaz and Double K are the only ones worth buying. Some are pricey, but they last forever ( built for near 24 X 7 service with doggies) and make a tornado in any radio you are working in, without the loud azz motor of a air kompressar.
