Default Cleaning options

A couple options for cleaning airplane parts. I have used ultrasonics baths, mostly flux removal on brazed pitot tubes. Most machines are 40 kHz, which have lots of power, but the 100kHz machines have smaller bubbles and penetrate pores better. Ultrasonic cleaning will blast holes in aluminum foil in less than a minute. Do a test piece first. Another choice is dry ice blasting. Our machine shaves off a block of dry ice and shoots it out like a sand blaster. Except no clean-up. The machines are expensive, but the principle is simple. Maybe a DIY project.
