The problem this solves

Restore your engine bay to a factory-finish look — without water, chemicals, or tear-down.

Years of grease, dust, oil mist and road grime build up across hoses, looms, plenums and the chassis rails. Traditional methods force a compromise: pressure-washing risks pushing water into electrical connectors and ECU plugs; degreasers leave a film that traps new dirt; tear-down for hand cleaning costs hours of labour. Dry ice blasting removes contamination from a cold engine bay in a single pass — pellets sublimate on contact, lifting grime away without leaving moisture, residue or abrasive media behind.

Benefits

Why dry ice for engine bay cleaning

Zero water in the bay

CO₂ pellets sublimate on impact. Nothing pools in connectors, looms or sensor housings.

No chemicals, no residue

No degreaser to flash off, no soap to rinse, no streaking on plastics or alloy.

Non-abrasive on every surface

Safe on plastic loom covers, painted plenums, alloy castings, hoses, decals and labels.

Faster than tear-down detailing

A typical engine bay takes 2–4 hours instead of a full day of disassembly and hand cleaning.

Concours-grade finish

Original factory textures, decals and serial markings remain visible — perfect for shows and pre-sale presentation.

Process

How a typical engine bay cleaning job runs

1

Pre-inspection

We mask sensitive sensors and air-intakes, photograph the bay, and identify decals or markings to preserve.
2

Pellet blast

Compressed-air dry ice pellets are blasted at the contamination. Pellets sublimate to gas; grime falls away dry.
3

Vacuum & detail

Loose debris is vacuumed; we hand-detail polished surfaces and apply protectant where requested.
4

Final walk-through

You inspect the bay before and after photos go to your customer file or insurance record.

Service-specific FAQs

Is dry ice safe for the engine?

Yes. The engine must be cool to the touch before we start. Dry ice pellets are non-conductive and non-abrasive. We mask sensitive sensors and intakes as a standard precaution.

Will it damage decals or factory markings?

No — we adjust pellet pressure for delicate areas. Original factory decals, VIN plates and warning labels remain visible. We pre-photograph any markings as a record.

How long does an engine bay take?

Most engine bays take 2–4 hours. Concours-grade work on heavily soiled or complex bays can run longer; we’ll quote a fixed price after inspection.

What does it cost?

Most passenger-vehicle engine bays sit between $480 and $950 depending on contamination, vehicle complexity and travel. Use our cost calculator for a postcode-specific estimate.

Do I need to drop the car off?

In most metro areas we come to you (workshop, driveway or detailing studio). Some specialty work is best done at a partner workshop with extraction.

Will the engine still need polishing afterwards?

Dry ice removes grime — it doesn’t add gloss. Most customers add a hand polish on alloy or plastic dressing on covers; we offer this as an add-on.

Does dry ice damage the aluminium or paint?

No. The pellets are softer than the surfaces and sublimate before they can cause abrasion. Painted finishes, anodised alloy and polished surfaces are unaffected.

How is this better than steam or pressure washing?

Steam and pressure washing introduce water into electrical connectors, looms and trapped corners. Dry ice doesn’t. There’s nothing to dry, no flashing, and no risk of moisture-related faults later.
