What builds up, and why it matters
On this kind of work the problem is oil, carbon, scale and hydrocarbon residue on generation and process equipment. Energy equipment is large, awkward to access and costly to take out of service, so cleaning in place during an outage is worth far more than a faster method that requires teardown.
Work is planned around outages and turnaround schedules. The people who call us about pump are usually operations and maintenance planners, and the thing they are actually worried about is extending an outage that was already tightly planned.
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 pump?
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
It is fast and it is wet, which is fine outdoors and unusable on anything with a winding in it.
- Solvent and degreaser
Good at softening, bad at leaving. There is always a residue and always a drum to get rid of.
- Hand scraping
Hours of work for an inconsistent result, with gouges where the blade slipped.
- Media blasting
Abrasive by definition. Anything with a tolerance or a finish worth keeping comes out changed.
- Dry ice
Thermal contraction cracks the bond between deposit and surface, then the pellet gasses off. Nothing abrasive, nothing wet, nothing left.
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.
- 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, fat, starch and sugar build-up on processing equipment, cleaned without chemicals touching a food 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
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.
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
Walk it with us before the hose goes away. A second pass while the compressor is still running costs nothing; a return visit costs us both.
- 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.
- 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
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.
What to expect on site
Expect noise. Everybody inside the working area wears hearing protection, us included.
Surfaces come out cold. On some jobs that means waiting a few minutes before handling, and on others it means condensation as the part returns to ambient temperature.
The rig needs compressed air, which the truck supplies. There is no hookup to find and nothing of yours to plug into.
Masking happens first. Whatever is adjacent and vulnerable gets covered before the hose is picked up.
Send us the job.
A short description and a location is enough to start. Add photos if you can. You will speak to an owner, not a scheduler.
