Dry ice blasting seems to be the new thing and actually something that delivers.
Engine bay is a bit dirty and was looking to rent one of the smaller machines as it’s just grime and dust I am getting rid of.
33 year old wire looms, harnesses, plastic, rubber, and all of the original engine bay stickers. The dry ice route seemed to be a good way to go.

Local place rents a big and small unit.
The small units need 50-100 CFM @ 80 psi. WOWZERS!!!!!!

My lovely little Porter Cable 25 gallon compressor weighs in at 5.1 CFM @ 90 PSI.

So I guess we’ll see $400 to rent the Dry Ice Blaster and $150 to rent a 90 CFM diesel compressor $250 in dry ice. Might be a little bit out of my cost benefit range. Maybe I can find a buddy that needs some stuff done and we could split the cost.

If you end up doing it, get a video. That is a pretty cool cleaning technique.

Definitely a neat technique.
Watched Tavarish do his flooded McLaren P1 with good looking results.

Didn't realize they need that much air behind them.

Where do you get that much dry ice and how do you kkep it available in an affordable manner?

Many welding gas suppliers have it available. I would just keep it in coolers and out of the sun.
For me it would be a single day rental and only a couple hours of work so it would keep just fine for my timeframe.

Bigger, longer jobs I could not speak to.
