Extruder Ice Blasting
When people call about extruder, the constraint is usually the same. We clean it without water, without chemicals and without anything abrasive touching the surface.
What builds up, and why it matters
On this kind of work the problem is baked-on process residue, oil film, carbon, swarf and release agent. Production equipment is expensive to take apart and expensive to leave down. Solvent means ventilation and disposal; water means waiting; abrasive means grit in a machine you just cleaned.
Most industrial work happens in place, during a shutdown or a maintenance window. The people who call us about extruder are usually maintenance leads and plant managers, and the thing they are actually worried about is that the line does not come back up on schedule.
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 extruder?
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
- Pressure washing
Water gets into everything and has to come out again before the equipment runs. Around electrics it is off the table entirely.
- Solvent and degreaser
Good at softening, bad at leaving. There is always a residue and always a drum to get rid of.
- Hand scraping
Slow enough to be uneconomic on a machine, and the tool always leaves a trace.
- Media blasting
It takes the top off whatever it touches. That is the point on rusted plate and the problem everywhere else.
- Dry ice
Cold breaks the bond and the media vanishes. The substrate is untouched and there is no second mess to clean up.
What comes off
The deposits we see most
Most calls involve one of the following. The common factor is a bond between two things that should not be bonded.
- Carbon and soot
Heat-bonded black deposit. Because heat put it there, a sudden cold front is what breaks its grip.
- Adhesive and sealant
Sealant squeezed out and cured where it was never supposed to set.
- Resin and mold release
Release agent and resin build-up on tooling, where a solvent fix trades one residue for another.
- Paint and coatings
Removed selectively where the substrate underneath has to survive, which rules out most abrasive approaches.
- 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.
How a job runs
What happens once you call
If you have not seen this done before, the process is worth reading once. Nothing below is hidden in a footnote.
- 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
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
The layout decides the method more often than the contaminant does. We work out reach and containment before quoting anything.
- We test a small area
Pressure and pellet size get dialed in on an inconspicuous spot before we touch anything visible. Painted parts, soft alloys and older finishes all behave differently, and the right setting on one is the wrong setting on another.
- 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 happens in your space
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.
Everything the rig needs arrives with it. No tap, no drain, no outlet.
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.
Send us the job.
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.
