914World.com _ 914World Garage _ Dry Ice undercarriage cleaning on a 914/6
Posted by: Cal Nov 5 2020, 09:02 AM
Here's very cool video that shows how effective dry ice cleaning can be on the underside of a 914 without removing or harming components. This company is based in CA. I wish there was a company that offered this service in the NE area.

Continental Carbonic has a Philly location and they rent dry ice blasting machines for a minimum of a week (don't know the cost) and can sell you the pellets also:

Dry Ice undercarriage cleaning!

WOW !
Clean and dry.
Imagine the labor savings and ability to preserve originality.
Incredible.

I get the 'no blasting residue', but not sure what other special properties it has over any other kind of pressurized blasting agent. The stuff it knocks off has to go somewhere and frankly I'm a little skeptical of the video where they clean the wheel wells and the paint is shiny perfect like it just came off the line.

I watched Army contractors use this method on some Black Hawk Helicopters. Simply put
it saved tons of time on clean up, they didn’t have to use harmful chemicals and it reduced there Hazardous Waste stream.

I understand you point and I have not heard a lot about it but with the little I have read. the material is not being abraded off (which would then make your question about not dulling or removing the underlying paint very appropriate) but rather freezes the material and the force both freezes and shatters the material leaving the underlining shiny paint. What I can't tell you is why the paint does not also freeze and shatter.

It’s not a abrasive but rather a cleaning process. “Regular” blasting uses the kinetic energy of the propelled media to mechanically manipulate the surface, whereas dry
blasting utilizes the phase change pressure differential energy, once the sold ice
collides with the substrate, to clean the surface.
No voodoo magic, just basic physics.

A really cool (pun intended) method to clean without damaging painted surfaces. The explanation of how the pellets attack the layer(s) of 'dirt' is broached on their web site.
I'm going to call the Los Angeles facility for pricing. If they have a minimum 1-week rental policy, might think about scheduling some local members to chip in to defray individual cost(s) and we can blast their cars on my lift during the week ... hmmmm

Turn up the air pressure from the compressor and the paint comes off:

This is another fun to watch cleaning video - including cleaning interiors with dry ice:

Hi all,
My '73 914 is sitting in LA waiting to be prepped for shipping to Australia.
I still need to find a company that can remove the undertray coating (with possible asbestos) before shipping. Dry ice stripping may be the answer to my problem. Does anyone know of somewhere where this could be done in or around LA?
I'm currently looking at a company in Arizona but if this could be done 'locally' it would be a bonus to my lousy Aussie dollar rate! lol! 
Cheers, Leonard

Looks good- I've heard of a place in the PHX area that does it but don't have an personal experience with it.
BTW, people from the 914-6 sway bar thread need to watch this as it has both F&R bars added...

Here in the states asbestos may be encapsulated rather than removed. Is it possible that Oz laws allow encapsulation? If so, a spray over of a compatible coating might be more cost/time effective than removal.

I live near San Diego and had my 71k mile 911 Ice Blasted at Cryowerks locally. Not an inexpensive proposition but the results are amazing.
To be fair I recently removed the heat exchangers and stripped & painted them with hi-temp silver so that brightens it up too.

Looks amazing... did this to my 77 911 the old-fashioned way, which was very expensive!
