What builds up, and why it matters
On this kind of work the problem is salt, corrosion product, oil, exhaust soot and bilge residue. South Florida salt air never stops working on a vessel. Abrasive cleaning takes the protective finish with the salt; dry ice removes the contamination and leaves the coating.
Work happens dockside, in the yard or aboard. The people who call us about marine dry are usually captains, yards and vessel owners, and the thing they are actually worried about is stripping a coating that was the only thing holding corrosion back.
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 marine 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
Drives water into harnesses, bearings, panels and seams, then everything waits to dry. On electrical work it is simply not an option.
- 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
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.
- Dry ice
It is the only one on this list where the media stops existing the moment it has worked.
What comes off
What dry ice actually removes
The rule of thumb is simple: anything stuck on rather than built in. These are the deposits we see most.
- Carbon and soot
Heat-bonded black deposit. Because heat put it there, a sudden cold front is what breaks its grip.
- Adhesive and sealant
The stubborn film under old tape, or the gasket that tore and left half of itself behind.
- 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
Taken off in a controlled way when what is underneath matters more than speed.
- Salt and corrosion product
The year-round problem on the coast. The finish holding corrosion back has to survive the cleaning.
- Ink and printing residue
Dried ink on precision roller faces, cleaned without altering the cell structure that does the work.
- Food residue
Carbonized product build-up in a plant where neither standing water nor a chemical film is acceptable.
How a job runs
How a job actually runs
Most people have never watched dry ice blasting happen and are not sure what they are agreeing to. Here is the whole sequence, start to finish.
- 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
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
Where the compressor sits, how far the hose has to reach, what gets masked or moved, and where the removed contaminant ends up. On food and electrical work this is most of the planning.
- 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
There is no spent media to recover, only the deposit, which we collect before packing up.
What the job is like to stand next to
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.
This is not a quiet method. Ear defenders are standard issue on site for anyone nearby.
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.
Everything the rig needs arrives with it. No tap, no drain, no outlet.
