I’ve used CO2 blasting for decontamination contaminated circuit cards and other sensetive electronics, and it works pretty well. By adjusting the pellet size in the CO2 gun you can affect the aggressiveness of the cleaning. I have found that it will easily rip off any foam that is present, such as thermal pads or shock absorbers. For dense liquids such as thermal paste it tends to push the material around.
Its very useful when cleaning items that are contaminated with flammable liquids since the CO2 supresses combustion.

Does this contribute to atmospheric CO2?

Depends on where they get the CO2 in the dry ice from. If it’s condensed out of the air, then it’s carbon neutral in a way, outside of the energy used to do it. If it’s a petroleum byproduct, then it’s not.

No filthy lint or hand oil or solvent streaks.

Brakleen is banned in California. It is arguably better for certain cleaning jobs than the alternatives. But it’s inarguably terrible for the environment and human health.
