Dry ice blasting and underseal services

Dry ice cleaning for vehicles, farm and factory machinery, electrical plant and buildings, at our Colchester workshop or on site anywhere in the UK. Vehicles can then be protected with underseal and inspected each year.

Underbody cleaning

We work along the underside section by section, lifting road dirt, grease, old wax and failing underseal from the floor pans, sills and chassis rails while the brake and fuel lines stay in place.

Pressure is reduced around delicate areas, and nothing is left in the seams or box sections. Any rust the clean reveals is photographed and discussed with you before protection is applied.

Wheel arches and suspension

With the wheels removed, the inner wings, springs, arms, hubs and subframes are cleaned in place, including the awkward areas behind brackets and around the suspension.

Bushes, seals and wiring stay fitted and unharmed. The arches are left clean and dry, ready for underseal the same day.

Engine bay cleaning

Oil, grease and road film are removed from the block, ancillaries and bulkhead with the loom, hoses and sensors left in place.

Because no water is used and nothing conductive remains, the electrics are not put at risk. Casting textures and factory markings survive the clean, which matters on original and concours engines.

Coating removal

Failing underseal, old wax such as Waxoyl or Dinitrol, and paint overspray are lifted back to the factory primer or bare metal without abrasion.

It is the cleanest way to see what lies beneath an old coating, and it leaves the surface ready for new protection, inspection or restoration work.

Agricultural, industrial and commercial dry ice cleaning

Where water, grit or solvent would harm the equipment or the building, dry ice is usually the better method.

Agricultural machinery

We bring the equipment to your farm and clean tractors, loaders, combines, balers, drills, sprayers and trailers where they stand.

With no water, grit or drying time, machinery can go straight back to work, and a combine cleaned after harvest is easier to inspect and store over winter.

Roller conveyors carrying boxes through a factory

Industrial and manufacturing

Injection and rubber moulds, foundry dies, core boxes, conveyors, press rollers and welding fixtures are cleaned in place, often while still warm and without dismantling.

Removing release agent, carbon and process residue this way shortens downtime and avoids the wear that abrasive cleaning causes.

Electrical and power

Electric motors, generators, switchgear, distribution boards and control panels are cleaned once isolated.

Dry ice is non-conductive and leaves no moisture, so dust, oil and carbon deposits come away without the drying time or corrosion risk that water and solvents bring.

Property and restoration

Soot and smoke residue after a fire, surface mould on joists and roof timbers, and old paint on oak beams, brick and stone can be removed without soaking the structure.

Every new surface is tried on a small test patch first, and the work suits occupied buildings because no chemicals or wet waste are left behind.

Marine and transport

Antifouling and marine growth are removed from hulls, rudders, keels and outdrives without grit or a wet slurry to contain.

The same method cleans boat, horse and plant trailers, lorry chassis and site plant, ready for inspection, repair or a fresh coating.

Filling head and conveyor on an automated production line

Food and drink

Ovens, proofers, conveyors, slicers, mixers, chocolate moulds and packaging machines are cleaned dry, with no water or chemicals left on the surface.

Equipment can often be cleaned in place and returned to service quickly. Dry ice cleans but does not disinfect, so your usual sanitation step still follows.

Underseal and protection

Applied straight after the clean, to bare, dry metal, so the coating bonds fully and lasts longer.

  • Lanolin-based

    A near-clear, flexible coating based on lanolin, such as Lanoguard. It goes on oily and cures to a waxy film over seven to ten days, repelling water from the start.

    Because the metal stays visible beneath it, any change can be seen at each inspection. It suits sound undersides and those with light surface rust.

  • Wax-based

    A thick cavity wax, such as Dinitrol or Bilt Hamber Dynax, in black or clear. It creeps into seams and box sections and is touch-dry in about 24 hours.

    It is the traditional choice for older cars, and for chassis rails, sills and other enclosed sections.

  • Ceramic coating

    A hard, gloss coating that resists stone chips and UV, and cures in about 24 hours.

    It suits undersides that are meant to be seen, such as show cars and finished restorations.

All three are inspected every year, or every 18 months for summer-only cars; see aftercare. Already coated with Waxoyl or Dinitrol? Note it in the quote form.

Underseal aftercare and annual inspections

We record what was applied, where, and when the next inspection is due.

  1. On the day

    A record for the history file: areas cleaned, products applied, and before and after photographs.

  2. The first two weeks

    Lanolin cures from oily to waxy and repels water from the start. Avoid jet washing underneath for the first two weeks.

  3. Every 12 months

    Back on the lift for an inspection, with the coating topped up where it has worn.

  4. Every 18 months

    For summer-only cars kept off salted roads.
