Dry Ice Cleaning vs. Manual Cleaning: Comparing the Total Job Cost

To compare dry ice cleaning vs. manual cleaning, price the complete job against the same acceptance criteria. An hourly crew rate and an employee’s hourly wage describe different things. Start with the work each option includes, then record the people, time, materials, and facility resources required.

Define one result for both methods

Choose a specific asset and deposit. State the surfaces included, material to retain, and condition required at inspection. Compare methods only after both have a credible route to that result. A faster pass that leaves unacceptable residue is an incomplete comparison.

Record the current method before changing it: who does the work, what is dismantled, which consumables are used, and when the asset returns to service. For a new application, arrange a representative test before treating proposed production rates as a budget.

Build a worksheet for the whole job

Use the same rows for each method. Enter actual records where available and identify estimates separately. The table below is a planning worksheet; it contains no assumed project prices or promised savings.

Cost or time item	What to measure for each method
Preparation and access	Staff hours for moving equipment, isolation, guarding, disassembly, and area protection.
Cleaning labor	Number of people multiplied by their total working hours, including support staff.
Equipment and supplies	Contractor or rental charges, consumables, compressed air, energy, and delivery.
Collection and disposal	Labor, containment materials, collection equipment, and waste handling.
Inspection and return to service	Checks, any rework, reassembly, and the facility’s release process.
Production interruption	Elapsed unavailability and the portion, if any, that affects usable output.

Keep labor hours and elapsed downtime separate

Record both the clock time and the combined hours worked by everyone involved. If several people work simultaneously, their labor hours add together while the elapsed time follows the schedule. Include customer staff supporting a contractor as well as the contractor’s crew.

For your internal comparison, use a consistently defined loaded labor cost. Note whether an apparent saving reduces paid overtime, frees existing employees for another task, or removes an outside expense. These are different outcomes and should have separate entries.

Review our machinery access guide when disassembly is a major part of the current process. Identify which preparation steps would actually change for the proposed dry ice work.

Assign a careful value to recovered production time

Ask the production and finance teams whether earlier availability could create usable output. Check demand, staffing, downstream capacity, and whether other maintenance tasks still control the restart. Keep any proposed production benefit separate from direct cleaning costs.

If you value additional output, document the method and assumptions with your finance team. Do not present gross sales per hour as profit or count the same labor saving twice. Where the opportunity is uncertain, show the cost comparison both with and without it.

Measure the dry ice side on your application

Ask the proposal to identify the crew, materials, air supply, setup, collection, and exclusions. Cold Jet notes that dry ice use varies by application and system, so use measured consumption or an explicitly qualified estimate for your own scope. See its technical FAQ.

Record replenishment, repositioning, and collection during the trial, not just the most effective cleaning pass. If the proposed method needs a different level of access or a second cleaning step, include that work in the comparison.

Make the decision from a range, then review it

Build a base case from observed results and a more demanding case for heavier deposits, limited access, or delays. Identify which inputs change the decision. For recurring work, revisit the comparison after completed jobs and use those observations when discussing the next maintenance interval.

A small, accessible manual task may be a different purchasing decision from a recurring equipment-cleaning shutdown. Let the defined work and measured costs guide the choice.

Get a comparable project scope

Use the pricing guide and quote comparison checklist to prepare your request. Share the current cleaning method, target assets, frequency, location, and available window, then request a project quote. For repeat requirements, explore scheduled maintenance planning.
