Ojus dry ice blasting
When we take a job in Ojus, the rig comes to the machine rather than the other way round.
The practical side
The compressor runs off the truck, so there is no wash pad to find and no runoff to manage. Which means no downtime spent in transit and no risk of damage moving it out of Ojus and back.
The media is gone by the time it has done its work, so there is no sand to vacuum and no water to mop. Only the contaminant is left, and that leaves with us.

Questions from Ojus
How do I get started?
A short description and a couple of pictures is enough to start. An owner rings you back.
Is Ojus in your area?
We do. The whole point of a mobile setup is that Ojus is no further than any other stop on the schedule.
What does the site need to have?
Access to the equipment and somewhere to park the compressor. No water hookup, no drain and no wash bay.
Can you work around our schedule?
Usually. Tell us the window you have, including overnight or a planned shutdown, and we will tell you honestly what fits in it.
Who calls you around here?
A mix, vehicle work, shop equipment, marine and light industrial. Same rig, different constraint each time.
Is there a travel charge?
Distance can factor in. You will hear about it up front, not on the invoice.
Why Ojus equipment ends up like this
Humidity is the constant. Anything bare oxidizes faster than it would almost anywhere else. So the job is usually less about scrubbing harder and more about not making the underlying problem worse.
The mix here runs from vehicle work in driveways to production equipment inside industrial units. Whatever the setting, the rig arrives with its own compressor and containment, so nothing about the site has to change to accommodate us.
Because the media sublimates, there is no slurry running toward a storm drain and no grit left in a machine. On a tight site in Miami-Dade County that is often the deciding factor.
What comes off
What comes off, and why
The rule of thumb is simple. If something is stuck on top of the material rather than being the material, dry ice has a good chance of lifting it. These are the deposits we get called about most.
- Food residue
Burnt-on product, fat and sugar on processing gear, with no chemical residue left on a contact surface.
- Grease and oil
Where heat is involved the grease cooks on and hardens. The cold breaks its bond and the film lifts away without soap or solvent.
- Carbon and soot
Black buildup from heat and smoke on burners, housings and fixtures. Thermal shock does the work here, with no grit grinding at the part.
- Adhesive and sealant
The stubborn film under old tape, or the gasket that tore and left half of itself behind.
- Resin and mold release
Release agent and resin build-up on tooling, where a solvent fix trades one residue for another.
- Paint and coatings
Selective removal, layer by layer, on parts where media blasting would cut into the substrate.
- Salt and corrosion product
A constant in South Florida. Removing it without stripping the protective finish is the whole trick.
How a job runs
Nothing about this should be a surprise
Nobody should have to guess what they booked. This is every stage of a job in the order it happens.
- You describe the job
Send images if you can, they settle most of the questions. A wrong-tool verdict comes on that first call, not after the invoice.
- We look at access and containment
Siting the compressor, masking what must not be touched, and catching what comes off, settled before the first pellet.
- We test a small area
The test is short and it is never skipped. Getting the pressure and pellet size wrong on a visible face is the one mistake this method can make, and a hidden patch is how we keep from making it.
- We blast, then clean up
There is no spent media to recover, only the deposit, which we collect before packing up.
- You look before we pack up
A second pass while everything is still connected is free in every sense. A return trip is not.
The comparison
The other ways to do this
- Hand scraping
Slow enough to be uneconomic on a machine, and the tool always leaves a trace.
- Media blasting
Abrasive by definition. Anything with a tolerance or a finish worth keeping comes out changed.
- Pressure washing
Forces water where water should not go, looms, bearings, seams, and then the job stops while it dries.
- Solvent and degreaser
Softens the contaminant but leaves a film, fumes and a disposal problem, and attacks finishes you meant to keep.
- Dry ice
Thermal shock breaks the bond. The pellet sublimates, so nothing abrasive touches the part and nothing is left to collect but the contaminant.
What to expect on site
We cover what should not be hit before anything gets blasted. It takes minutes and saves arguments.
Solid carbon dioxide leaves no residue at all. What it does do is displace air, so an enclosed space gets ventilated as part of the job rather than as a precaution added later.
The noise is the one thing that surprises people the first time. It stops the moment the hose does, and nothing about it lingers.
If you plan to put the part back to work right away, allow a few minutes. It comes off cold and may gather condensation before it reaches room temperature.
