Rags soaked in odorless mineral spirits might remove what he leaves , or finish up some spots.
Would be best to have it on a rotisserie if working with the rags.

Can understand the cost restraints , and the excessive nature of what was applied.
But if price were no obstacle , it would be worth going full monte.

I have my car back from the dry ice blaster. Yes, I was the guinea pig for this little experiment. Here is my honest assessment. The process works as advertised. It really cleans and removes old scale, loose paint and undercoating. But here is the catch. It is an EXTREMELY slow process. I would liken it to sand blasting the entire underneath of a car with a tiny siphon feed, Harbor Freight sand blaster. So with a cost of $250.00 an hour, now that I have the car back, it would have cost $4000.00-4500.00 to remove all the thick rubbery undercoating covering the entire underneath. I had a 6 hour limit, that's all I could put into this tiny portion of the entire job. He removed about 50% of what I was hoping to remove. That's life. It looks way, way better than it did. I had to forgo the rear axle, leaf springs and some other areas I wanted to blast. They can always be done at a later time. So for someone where money is no object, dropping 4K+ to really clean the underneath may be a good investment. BTW, he used 350 LBS of pelletized dry ice and it's about $400.00 for a 500 lb. tote. That cost was included in my service. I will post some pics when I get it back on the lift in my shop next few days.

I wonder what field/necessity caused dry ice blasting to originate .
Must have been something smaller scale to use such small appliances.

The AirForce was using dry ice blasting in the 80's.

We used dry ice blasting in the 80s to clean underground coal mining equipment.
