Working on the Wife's Jag, got the intake apart. Took some parts to work to dry ice blast clean TB and intake parts.

 

Cool.

Yes, pun very much intended...

 

I've never come across that before. It was hard for me to tell from the video how effective it was.
What is the principle behind this method?, I'm guessing rapid freezing on gums and contaminants makes them come off easily, and dropping anything might result in it shattering, but this is conjecture on my part.

When I worked in an automotive factory we would use ice blast to clean the tooling of weld soot and light slag deposits also grease and oil would be removed as well. The gun we used was 4 times that size but same principle. It uses compressed air to fire small CO2 pellets similar to media blasting. The nice thing is that the CO2 pellet evaporates leaving no residue. Really need to be careful handling it due to frost bite potential. I have also seen it used on sites reconditioning old timbers that had been white washed many years ago. Stripped the paint off leaving clean wood with the only residue being bits of the paint on the ground.

That's all it is...

The reality is that the friction at impact vaporizes the CO2 pellets long before they can heat the part. This process has become common for stripping aircraft, again due to the "environmentally friendly" aspect of leaving no residue. It's a lot like soda blasting.

 

Thanks guys. I'm better informed than when I last logged in .
