What builds up, and why it matters
On this kind of work the problem is fine dust and particulate loading on switchgear, busway, fans and mechanical plant. A data hall cannot take water and cannot take downtime. Cleaning has to be dry, contained, and finished inside the window you were given.
Work is planned around the maintenance window and the containment the facility requires. The people who call us about data center equipment are usually critical facility and data center operations teams, and the thing they are actually worried about is particulate migrating somewhere it should not, or a window overrunning.
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 data center 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
- 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
Forces water where water should not go, looms, bearings, seams, and then the job stops while it dries.
- Solvent and degreaser
It loosens the mess and leaves its own behind, along with fumes and something to dispose of.
- Hand scraping
Fine on a patch, hopeless on a machine, and the blade leaves its own evidence.
- Dry ice
It is the only one on this list where the media stops existing the moment it has worked.
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.
- Grease and oil
Oil film is the layer everything else sticks to. Remove it and half the job is already done.
- Carbon and soot
Heat-bonded black deposit. Because heat put it there, a sudden cold front is what breaks its grip.
- 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
Cured process residue on a mold or fixture. The surface has to come out dimensionally unchanged, which rules out anything abrasive.
- 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.
- Ink and printing residue
Dried ink on precision roller faces, cleaned without altering the cell structure that does the work.
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
We start with what it is and what is on it. Whether it can come offline matters as much as the contaminant, and a wrong-tool answer is one we give up front rather than after the invoice.
- We look at access and containment
Hose run, compressor position, what needs masking, and where the contaminant is collected. For food and electrical jobs the containment plan takes longer to settle than the blasting does.
- We test a small area
Settings get proven somewhere nobody looks before they get used somewhere everybody does. What is correct on cast iron will mark aluminum, so the test is not a formality.
- We blast, then clean up
Nothing is left of the pellet, so the only thing to collect is what was on your equipment. That collection is part of the work we quoted.
- You look before we pack up
The job is not finished because we say so. It is finished when you have looked at it.
What to expect on site
The rig needs compressed air, which the truck supplies. There is no hookup to find and nothing of yours to plug into.
Anything nearby that should not be touched gets masked before we start. That is quicker than explaining it afterward.
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.
