What builds up, and why it matters
On this kind of work the problem is dried ink, adhesive, paper dust and coating build-up. Anilox and press rollers are precision surfaces. Anything abrasive changes the cell structure and changes the print, which is why solvent soaking and manual scrubbing are the usual compromise.
Presses are cleaned in place between runs or during planned maintenance. The people who call us about labeling equipment are usually press operators and production managers, and the thing they are actually worried about is altering a roller surface and with it the print result.
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 labeling equipment?
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
Why not just pressure wash it
- Solvent and degreaser
It loosens the mess and leaves its own behind, along with fumes and something to dispose of.
- Hand scraping
Labor-intensive and uneven, and whatever you scrape with eventually marks what you are scraping.
- Media blasting
It works by removing material, which is the problem. Acceptable on heavy steel, damaging on soft alloy, plating or a machined surface.
- Pressure washing
Water gets into everything and has to come out again before the equipment runs. Around electrics it is off the table entirely.
- 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 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.
- Ink and printing residue
Dried ink and coating build-up on rollers and press components, where the surface texture is the product.
- Food residue
Burnt-on product, fat and sugar on processing gear, with no chemical residue left on a contact surface.
- Grease and oil
Oil film is the layer everything else sticks to. Remove it and half the job is already done.
- Carbon and soot
Baked carbon on a manifold, oven or weld fixture. Thermal shock is exactly the wrong thing for the bond holding it on, which is why this works.
- 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
Taken off in a controlled way when what is underneath matters more than speed.
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 look before we pack up
Inspect it with the rig still set up. Anything you are not happy with gets another go before we leave.
- You describe the job
What it is, what is on it and whether it can stop. If the answer is that dry ice is wrong for it, you get that answer first, not last.
- We look at access and containment
How close the truck can get, how far the hose must run, what needs covering, and where the debris goes. That is the bulk of the planning on a tight site.
- 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
One mess instead of two: the pellet vanishes and we take away what it removed.
What to expect on site
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.
Dry ice is carbon dioxide in solid form. It is non-toxic and leaves no residue, but it does displace oxygen in an enclosed space, so ventilation is part of the setup rather than an afterthought.
Expect noise. Everybody inside the working area wears hearing protection, us included.

Tell us what the machine is, where it is and what is on it. A photo or two speeds it up. One of the owners calls you back.
