Dry ice detailing

I'd be worried about it damaging paint or plastic bits but looks cool.
It's just removing grease and grime, right? Not rust...?

 

Removes paint and rust; kills and removes mildew.

 

Dry ice blasting has been around for a while. I've used it at work many, many times. It works great! The best part is that the cleanup is only what material/dirt was removed. I like it for work because I can clean filling lines, mixing tanks, storage tanks, etc. all without having water all over the floor (if I pressure washed it), creating a safety hazard. I've taken a few motorcycle parts to the same place and had them clean them up as well.

 

A good applicator can adjust pressure and pellet size so as to not damage more delicate pieces. I'm sure there's a limit, but a good contractor can tell you if it can be done. FWIW, if you're in the St. Louis metro area, I've used Starr Restoration at work. Great guys to deal with. I've no affiliation with them other than they did work for me several years ago.
