What builds up, and why it matters
On this kind of work the problem is whatever is bonded to the surface rather than part of it. Sometimes the job is named after the contaminant instead of the machine. The method is the same: thermal shock breaks the bond and the contaminant releases.
Scope is set by what has to come off and what must survive underneath. The people who call us about wax removal with dry are usually anyone with something stuck to something else, and the thing they are actually worried about is taking the substrate along with the coating.
The method
Why dry ice and not the alternatives
- Non-abrasive
The pellet is soft and sublimates on impact, so the work is thermal rather than mechanical. Machined faces, plating, paint and gaskets survive it.
- Low moisture
No standing water in a harness, a bearing or a cabinet, and no dry time before the equipment goes back into service.
- No secondary waste
Sand, soda and walnut shell all have to be swept and hauled. Dry ice leaves only the contaminant it removed.
- Often no teardown
Much of this work is done in place, which is usually where the real saving is. The labor is in the disassembly, not the cleaning.

Questions we get asked first
Will it damage the surface underneath?
On most substrates, no. The pellet is soft and sublimates on impact, so it does thermal work rather than mechanical work. We still test an inconspicuous spot first on anything unusual.
Do you have to take the equipment apart for wax removal with dry?
Usually far less than you would expect, and often not at all. Cleaning in place is where most of the saving comes from, because the labor is normally in the teardown and reassembly.
How much mess does it make?
Far less than the alternatives, because the blasting media disappears. What is left is the contaminant itself, which we contain and clean up.
Do you come to us?
Yes. The whole rig is mobile. Compressor, hose and operator arrive at your shop, plant, driveway or dock, anywhere across South Florida from Miami out to roughly a hundred miles.
What does a job cost?
It depends on the equipment, the contaminant and the access, so we will not throw a number at you over the phone without understanding the work. Describe the job and we will give you a real figure.
How soon can you look at it?
Send photos and a short description and one of the owners gets back to you. If you have a shutdown or a deadline, say so up front and we will tell you honestly whether we can hit it.
The comparison
What the alternatives actually do
- Pressure washing
Pressure pushes moisture past seals and into connectors, and then you wait. Panels and motors rule it out.
- Solvent and degreaser
Trades the deposit for a residue, plus ventilation and waste to deal with, and it is hard on the finish.
- Hand scraping
Fine on a patch, hopeless on a machine, and the blade leaves its own evidence.
- Media blasting
It takes the top off whatever it touches. That is the point on rusted plate and the problem everywhere else.
- Dry ice
The pellet is soft and the mechanism is temperature, not abrasion. It turns to gas on impact, so the only thing left to sweep up is what came off.
What comes off
The deposits we see most
Most calls involve one of the following. The common factor is a bond between two things that should not be bonded.
- Carbon and soot
The hard black crust on a housing, an oven or a weld cell. Bonded by heat, and the first thing to release under thermal shock.
- Adhesive and sealant
Whatever the last repair left stuck to the mating face: gasket, sealant, deadener or adhesive.
- Resin and mold release
Production residue cured onto tooling. Solvent softens it and leaves its own film; the ice lifts it and takes nothing with it.
- Paint and coatings
Removed selectively where the substrate underneath has to survive, which rules out most abrasive approaches.
- Salt and corrosion product
A constant in South Florida. Removing it without stripping the protective finish is the whole trick.
- Ink and printing residue
Dried ink and coating build-up on rollers and press components, where the surface texture is the product.
- Food residue
Carbonized product build-up in a plant where neither standing water nor a chemical film is acceptable.
How a job runs
What happens once you call
If you have not seen this done before, the process is worth reading once. Nothing below is hidden in a footnote.
- 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
An out-of-sight patch comes first so pressure and pellet size are proven before anything that shows. Soft alloys, older paint and bare metal each want different numbers.
- We blast, then clean up
The ice is gone the moment it does its work. What stays behind is the grease or carbon that came off, and collecting that is part of the job, not an extra.
- You look before we pack up
The job is not finished because we say so. It is finished when you have looked at it.
- You describe the job
The machine, the deposit and the downtime you can afford. Those three things decide the whole job, and we would rather know all of them before quoting.
What happens in your space
The media is solid CO2, nothing toxic and nothing left behind, but it pushes oxygen out of a closed room. Ventilation gets planned before the hose is connected.
This is not a quiet method. Ear defenders are standard issue on site for anyone nearby.
The part will be cold when we finish. Sometimes that means a short wait before handling; sometimes it means a film of condensation as it warms back up.
Everything the rig needs arrives with it. No tap, no drain, no outlet.
