In-house cleaning or outsourcing? When each route pays off
Production companies considering dry ice blasting face one principal choice. Buy your own machine and clean in-house, or hire an external service when needed. Both routes have cost structures that only reveal themselves under regular use. The wrong choice costs tens of thousands of euros over five years.
This article explains the decision framework ColdBlast applies with production companies. You will learn when an in-house cleaning machine pays back, when outsourcing is the smarter route, and how to calculate your own scenario in our ROI calculator.
What we mean by in-house cleaning and outsourcing
In-house cleaning means your maintenance team or production operators run a dry ice blasting machine themselves. ColdBlast supplies the machine, dry ice or production option, training and service. You decide when to clean, how often and with whom. The machine sits inside your production and runs whenever it suits the line best.
Outsourcing means an external cleaning service comes to your location. They bring machine, dry ice and operator. You pay per job, usually per day or per project. ColdBlast connects clients with incidental cleaning demand to fixed service partners; the technology stays Cold Jet, execution sits externally.
When an in-house dry ice blasting machine wins
An in-house machine wins as soon as cleaning recurs structurally. Weekly or more frequent cleaning means the capital investment pays back quickly on avoided service invoices and wait times. For in-press mold cleaning in injection molding the win is even sharper; your operator can clean during a planned press stop without having to schedule an external party.
An in-house machine also wins at high downtime costs. Waiting for an external service means paying production loss for every day of scheduling. ColdBlast sees at food producers and injection molders that in-house cleaning saves four to eight hours per cleaning moment, because the machine is directly available. Across a production year that quickly compounds to dozens of cleaning sessions.
When outsourcing wins
Outsourcing wins for incidental cleaning demand. A production company with one or two major sanitation actions per year cannot amortise an own machine on six cleaning sessions. A service partner is then more economical. For one-off projects such as fire restoration, monument cleaning or one-time remediation work, outsourcing is also the right route.
A second situation where outsourcing wins is the validation phase. Production companies that still need to verify whether dry ice blasting works on their specific contamination can have a trial cleaning carried out via a ColdBlast service partner first. Only when the technology proves itself does the investment decision follow.
Decision matrix
The matrix below summarises the choice across the two dominant variables, cleaning frequency and downtime cost per hour.
| Situation | Recommended route | Why |
|---|---|---|
| Weekly cleaning, high downtime cost | In-house machine | Fast payback, no waiting time |
| Monthly cleaning, moderate downtime cost | In-house or lease | Ownership pays back within 24 months |
| Quarterly cleaning, plannable | Lease or service contract | Fixed monthly fee, flexible deployment |
| One to two times per year | External service | No investment, pay per job |
| One-off project, remediation or restoration | External service | No continuous investment needed |
| Validation or pilot phase | External service first, reassess later | Prove the technology on your contamination first |
5-year cost comparison
The table below shows an indicative 5-year comparison for a production company with two cleaning hours per week. Figures are orders of magnitude; your situation can differ on operator rate and cleaning frequency.
| Route | Investment | Annual cost | 5-year total |
|---|---|---|---|
| In-house Cold Jet machine | 25,000-35,000 | 8,000-12,000 | 65,000-95,000 |
| Lease via ColdBlast | none | 15,000-22,000 | 75,000-110,000 |
| External service (weekly) | none | 40,000-60,000 | 200,000-300,000 |
| External service (incidental, 4x per year) | none | 8,000-15,000 | 40,000-75,000 |
At weekly cleaning an in-house machine wins by a wide margin on 5-year totals. At incidental cleaning external service wins. The ColdBlast ROI calculator runs your exact scenario based on your cleaning frequency, operator rate and downtime cost.

Frequently asked questions
How often do I need to clean before an in-house machine makes sense?
A rule of thumb from ColdBlast practice; from around 50 cleaning hours per year an in-house Cold Jet machine pays back within 24 months. Weekly cleaning typically puts you well above that threshold. Our ROI calculator runs your exact break-even point.
How much does external dry ice cleaning cost?
External service ranges indicatively from 1,200 to 2,500 euros per day, depending on location, machine type and project size. For one major annual cleaning action that is reasonable. For weekly cycles it quickly exceeds the annual cost of an in-house machine.
Does lease lower the threshold to clean in-house?
Yes. Lease removes the one-off investment and replaces it with a fixed monthly fee. For production companies still uncertain about their cleaning frequency, lease provides access to a Cold Jet machine without tying up capital. See the lease options at ColdBlast.
Who supplies the dry ice if I clean in-house?
ColdBlast advises on dry ice supply via fixed partners in the Netherlands. You can choose regular delivery on fixed days, or an own pellet production machine at high consumption. For most production companies regular delivery is sufficient.
What does ColdBlast do when I am unsure about the route?
ColdBlast visits your site for a demo or trial cleaning on your own contamination. You see directly how a Cold Jet machine responds to your specific production. We then calculate the 5-year scenario together for ownership, lease and external service.
Is in-press mold cleaning possible with external service?
Technically yes, but the gain almost always disappears. In-press cleaning works best when an operator can clean immediately during a press stop. An external service has to be scheduled and dispatched, which eliminates the downtime gain. For in-press cleaning, in-house almost always wins.
How does my choice change as production volume grows?
As your production grows, cleaning frequency usually grows with it. An external service contract that works today becomes expensive two years later. ColdBlast advises to recalculate the 5-year scenario whenever capacity expansion plans appear.
