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 production residue removal 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 production residue removal?
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
How this compares to the usual methods
- Solvent and degreaser
It dissolves the deposit and often the finish underneath, then leaves a film behind either way.
- Hand scraping
It is the fallback when nothing else is available, and it shows on the surface afterward.
- Media blasting
Cuts into the substrate by design. Fine on structural steel, wrong on aluminum, plating, machined faces or anything with a tolerance.
- Pressure washing
Pressure pushes moisture past seals and into connectors, and then you wait. Panels and motors rule it out.
- 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
What comes off, and why
If it is bonded to the surface rather than part of it, there is a good chance this takes it off. The list below covers most of what we are called out for.
- Adhesive and sealant
Sound deadening, tape residue, gasket material and sealant that has cured onto a face it was never meant to stay on.
- Resin and mold release
Release agent and resin build-up on tooling, where a solvent fix trades one residue for another.
- Paint and coatings
Taken off in a controlled way when what is underneath matters more than speed.
- Salt and corrosion product
Salt deposit and the oxidation it starts. Anything abrasive removes the protection along with the salt.
- 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.
- Grease and oil
Oil film is the layer everything else sticks to. Remove it and half the job is already done.
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.
- 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
If something needs another pass we do it then, on site, while the rig is still running. That is a better outcome for everyone than a callback.
- You describe the job
Tell us the machine, the mess and the constraint. A couple of photos answers more than a long description, and if the honest answer is that something else suits it better, we say so.
- 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.
What to expect on site
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.
Air comes from our own compressor. You do not need to provide power, water or a connection of any kind.
We cover what should not be hit before anything gets blasted. It takes minutes and saves arguments.
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.
Describe what you are dealing with.
Give us the job, the address and a rough description, pictures if you have them. The call back comes from Giancarlo or Kenny directly.
