Underseal removal with dry ice
Dry Ice Underseal Removal
Old and failing underseal removed with dry ice blasting. No grinding, no grit, no hazardous fallout. Clean metal, ready for inspection and protection.

When underseal stops protecting
Underseal ages. It hardens, cracks and lifts at the edges. Water gets behind it and stays there, against the metal, out of sight. By the time it flakes away, the corrosion beneath is often well established.
Removing it conventionally means scrapers, heat guns, wire wheels or media blasting. Slow, messy and hard on original metal and rubber components.
Dry ice blasting removes it by thermal shock. The extreme cold makes aged underseal brittle, and the impact fractures it cleanly from the substrate. Each CO₂ pellet sublimes on impact, so the only waste is the old coating itself.
Why dry ice
Why dry ice for underseal removal
Every conventional removal method risks the metal it is meant to reveal.
No abrasive damage
No grinding and no grit. Original metal, seams and factory stampings are left intact.
No hazardous fallout
No blasting media to contain or dispose of. Only the removed coating to collect.
Rubber stays protected
Gaiters, bushes, CV boots and seals need no masking against grit, because there is none.
The process
How we remove underseal
Every vehicle is assessed individually. This is not a car wash and not a valet service.
- 01
Assess
Existing coatings reviewed. Sound factory underseal identified and discussed.
- 02
Dry ice removal
Failing underseal fractured from the substrate by thermal shock.
- 03
Inspect
The true condition of the metal, laid bare. Findings discussed before anything else happens.
- 04
Protect
A new protection system applied to clean, dry metal.
Corrosion protection
What goes back on
Protection applied to bare, contaminant-free metal bonds harder and lasts longer than the same product laid over road film. We hold four systems in-house and recommend by vehicle, storage and goal, rather than leading with one product.
Lanoguard Clear
Short-term protection, reapplied annually. Suited to vehicles in active use or stored outdoors.
2 yearsBilt Hamber Dynax-UB
Wax-based protection. The pragmatic choice for daily-use classics and weekend cars.
Around 5 yearsDinitrol Full System
A professional preservation system, applied as part of a full programme, with annual inspection and maintenance.
Longest-lastingCeramic Underbody Coating
The long-term option for high-value vehicles, maintained by annual inspection.
Each system has a recommended maintenance interval. We record yours and, with your permission, remind you when it is due, much like an MOT. Protection periods are maintenance intervals, not warranties.

Your vehicle collected from your door by our trusted dedicated car transport partner, anywhere in the UK, and delivered back once the work is complete. Quoted with your assessment.
Questions
Frequently asked questions
Do you always remove underseal?
No. Sound factory underseal is generally worth keeping, and a standard dry ice clean preserves it. Full removal is for coatings that have failed, and is quoted separately.
Will dry ice remove bitumen-based underseal?
Yes. Thermal shock is particularly effective on aged bitumen and rubberised coatings.
What happens to the old underseal?
The CO₂ leaves no residue, so the only waste is the removed coating, which is collected and disposed of.
What happens after removal?
The metal is inspected. Any corrosion is discussed with you, with repair arranged where needed, before a new protection system is applied.
