Frequently Asked Questions
Everything owners ask about automotive dry ice blasting, rust treatment, underbody preservation, timings and booking – grouped by topic so you can jump straight to what matters.
Dry Ice Blasting
What types of vehicles are best suited for dry ice blasting?
Dry ice blasting is particularly suited to classic cars, modern performance vehicles, and well-maintained daily drivers where preservation of original materials is important. It is commonly used on underbodies, engine bays, wheel arches, and complex assemblies where abrasive or water-based methods would be inappropriate.
What makes dry ice blasting more effective than pressure washing or sandblasting?
Pressure washing drives water into seams, cavities and electrical components – exactly where you don't want it on a classic. Sandblasting is abrasive and removes the substrate along with the contamination. Dry ice sublimates on impact: no moisture, no abrasion, and no spent media to clean up. It is a fundamentally different technique built around preservation, not surface removal.
Is dry ice blasting safe for electrical components, brake lines and fuel pipes?
Yes, when carried out by a trained operator. Pressure, nozzle and standoff distance are adjusted for sensitive areas, and components that should not be exposed are masked or worked around. We routinely clean around looms, sensors, brake hardware and fuel lines without damage.
Is dry ice blasting safe for my vehicle and the people doing it?
Yes, when carried out properly. Dry ice is frozen, food-grade carbon dioxide that sublimates straight to gas, so there is no liquid, no abrasive grit and no toxic chemical residue left on the car. The work is done in a ventilated workshop with the correct protective equipment, and pressure and standoff distance are matched to the surface so original finishes, seals and components are preserved.
Will dry ice blasting damage original paint, undersealing or factory finishes?
No. The technique is non-abrasive and non-chemical, and it does not remove sound original coatings. Factory undersealing and original paint are preserved while contamination, loose oxidation and degraded overlays come away. Pressure is always adjusted to suit the surface in front of the operator.
Can dry ice blasting be used on vehicle interiors?
Selectively, yes. It is excellent on bare metalwork, bulkheads, transmission tunnels and exposed structural areas during a restoration. We do not use it on trimmed cabins or finished upholstery, where other techniques are more appropriate.
Rust & Corrosion
Can dry ice blasting remove rust?
Dry ice blasting removes loose surface oxidation and contamination, exposing the true condition of the substrate underneath. Active corrosion is then stabilised with the appropriate rust treatment as a separate stage. The combination is what makes the long-term protection systems work; dry ice blasting alone is not enough.
What happens if corrosion holes or weak metal are discovered?
Once the contamination is removed, the true condition of the metalwork becomes visible. We document anything we find, share photographs, and discuss the appropriate next step before going further. We will not seal over a problem to make a job look finished.
Can you underseal over rust?
You physically can, but covering rust is not the same as dealing with it. If corrosion, dirt, moisture or old coating is still present, the new underseal bonds to that contamination rather than to clean metal, so over time it can lift, trap moisture and hide the problem until it is worse. To hold rust back properly the underside needs to be cleaned so its true condition is visible, any corrosion stabilised, and protection applied evenly to sound metal and allowed to cure. Underseal is useful as the final protective stage, not as a way to hide what is already there.
What happens if you find rust underneath the car?
In most cases it is better to know early. The worst corrosion is usually the hidden kind – under old underseal, behind arch liners, around seams and on subframes – not the areas you can already see. Caught early, light surface corrosion on a suspension arm, sill edge or subframe mount may only need cleaning, stabilising and protecting; left for several more winters, the same area can become a far larger repair. We clean and inspect first, then document and discuss anything we find before going further, so the aim is clarity rather than unnecessary worry.
Does bad corrosion always mean parts need replacing?
Not always. Where corrosion has caused structural weakness, perforation or serious metal loss, replacement or welding may be the right route. But many parts that look poor under road dirt and old coating can be cleaned, assessed and treated once their real condition is visible – we use dry ice blasting to remove contamination, with targeted laser cleaning where corrosion is more bonded, then stabilise and protect where appropriate. Replacement should be based on condition, not guesswork, which matters most on classic and collector cars where unnecessarily replacing original parts can affect value.
How do I know if my car's underside is actually in good condition?
From underneath with a torch many cars look fine, but the underside can hide rust beneath old underseal, corrosion behind arch liners, moisture trapped around seams and previous repairs under fresh coating. A visual check is useful, but it is not the same as a proper clean and inspection. The only way to understand the true condition is to remove the contamination and look at what is underneath, which is why many owners choose dry ice blasting before any protection – it gives a clear baseline. Sometimes the car is better than expected and sometimes it needs more treatment, but either way the decision is based on evidence.
Underbody Preservation
Do you offer Lanoguard treatment?
Yes. Lanoguard is one of the protection systems available to us, alongside Dinitrol, Bilt Hamber and premium ceramic options. The right system depends on the vehicle, its use and how often it sees the road. We recommend based on condition rather than brand preference.
Can dry ice blasting improve resale value?
A documented preservation history makes a real difference to a serious buyer. Photographs, treatment records and a clean, protected underbody all support the asking price and shorten the conversation when the car changes hands.
Why does preparation matter more than the coating?
The coating is only as good as the surface underneath it. A premium product applied over dirt, loose rust, moisture or failing underseal will not perform as it should, and the problem is usually the preparation rather than the product. Before protection the underside needs to be assessed properly – wheels, arch liners and undertrays off where required, then cleaned so the true condition can be seen. Only then can the right call be made on clear or black protection, cavity wax, rust treatment first, or welding before anything is sealed.
What is the difference between a quick clean and a preservation programme?
A quick clean is about appearance; a preservation programme is about condition, treatment and long-term protection. A wash can remove loose dirt and improve presentation, but if you are keeping the car, appearance alone is not enough. A programme considers what is currently on the underside, whether old coatings are hiding corrosion, whether the metal is clean enough to treat, which areas need protection and which product suits the vehicle, whether the finish should be clear or black, whether cavities need wax, and how the work is documented. That is why preservation costs more than a basic clean – the labour is in access, inspection, dry ice blasting, rust treatment, coating, documentation and careful finishing.
What areas are usually included in an underbody preservation programme?
Every vehicle is different, but a programme usually focuses on the areas most exposed to road contamination and corrosion: the undercarriage, wheel arches, arch liners and undertrays, suspension arms, subframes, brackets and mounting points, chassis rails, sills and lower edges, engine bay underside areas, gearbox and differential casings, and cavities where cavity wax is required. Access matters – if wheels, arch liners and undertrays are left in place, important areas get missed, which is why professional work usually involves removing components before cleaning and protection. The more carefully the car is prepared, the better the final result.
Is underbody preservation only for rusty cars?
No – often the best time to preserve a car is before it looks rusty. Preservation is not only a rescue service for heavily corroded vehicles; it is also a preventative measure for cars that are clean, valuable, rare or meant to be kept long term, including modern performance cars, classics, prestige vehicles, 4x4s, imports and low-mileage collector cars. If a car is already clean underneath, preservation helps keep it that way; if early corrosion is present, treatment can stop it becoming a larger issue; and if the history is unknown, a clean and inspection provide clarity. The right programme depends on the condition of the vehicle and what you want to achieve.
Do restored classic cars still need underbody preservation?
Often, yes. A restored car may have had excellent paint, mechanical and trim work, but underbody preservation is a separate specialism and the underside is not always cleaned, documented and protected to the same level. If the restoration has just been completed it is the ideal time to protect the underside properly; if it was finished years ago, it is worth checking whether the original protection has thinned, worn or failed. For classics the goal is not just a presentable underside – it is preserving original components where possible and creating a documented record for maintenance, history and resale confidence.
Should I preserve the underside before or after winter?
If you intend to keep the vehicle, it is usually better to inspect and protect the underside before winter. UK roads expose cars to water, salt, mud and long damp spells, and even cars that are not used daily can suffer if they are stored somewhere cold or humid. Winter does not create every problem, but it accelerates ones that are already starting, so protection is most effective when the car is cleaned, dried, inspected and protected before months of wet or salty use. It can still be done afterwards – in that case the focus is removing the contamination built up over the colder months, then assessing and protecting.
Timings & Booking
How long does dry ice blasting take, and will you need to keep my car?
Most projects are with us for around a week, including inspection, blasting, rust treatment, curing time, protection application, reassembly and documentation. Signature Programme projects can take up to two weeks to allow for the full premium specification and full curing windows. We agree timings before booking so you know exactly when to drop the car off and collect it.
How soon can I get booked in?
Lead times vary with the season and the programme. Typically two to four weeks for a workshop slot, longer in the run-up to spring and concours season. Submitting the quote form first means we can hold a provisional date while the specification is finalised.
Is any preparation required before my booking?
No. Once the vehicle arrives, we’ll take care of everything. We’ll walk through the work with you, confirm any vehicle-specific details and make sure everything is clear before the process begins. Vehicles can be driven in, delivered by trailer, or we can help arrange transport where needed.
When should I get a quote for underbody preservation?
Get a quote once you know what you want to achieve with the vehicle – whether that is protecting a car you plan to keep, preserving a recent purchase, preparing a classic before winter, checking a restored car or treating visible surface corrosion. A good quote is based on the vehicle, its condition and your goal, so photos and videos of the underside are genuinely useful: they help us understand the current condition, the access required and which programme is most suitable. Some cars need a focused underbody and arches programme, others need engine bay cleaning, cavity wax, rust treatment or underseal removal, so the more we know at the start, the better we can recommend the right route.
Maintenance
How often should dry ice blasting be carried out?
Once an underbody has been properly cleaned and protected, the protection system does the work. Annual inspection is recommended to top up sealants in high-wear areas. Full reblasting is rarely needed unless the car has been used through several wet winters without maintenance.
Mobile, Collection & Other Services
Do you offer a mobile service, or can you collect and deliver my car?
A controlled mobile service is available for trade customers and specialist facilities, subject to ramp and access requirements. Collection and delivery for private customers can also be arranged on request, costed by distance. For full preservation programmes, the Oxfordshire workshop remains the most controlled environment.
Do you carry out other restoration work?
We stay in our specialism: dry ice blasting, corrosion stabilisation and long-term protection. For paint, mechanical or trim restoration we work alongside trusted specialists and can introduce you where it's helpful. Doing one thing properly is the point.
Pricing
How much does automotive dry ice blasting cost?
Pricing is condition- and specification-led. Tell us about your vehicle and what you want to achieve in the quote form and you'll get specific recommendations and a tailored quote, not a cold-call follow-up. Programmes start at the Underbody & Arches level and scale up to the full Signature programme.
Why is dry ice blasting expensive?
It is skilled, time-intensive work using commercial-grade equipment and consumable dry ice, carried out by a trained operator rather than rushed through a wash bay. The figure also reflects what sits around the cleaning – careful access and masking, corrosion assessment, rust stabilisation, long-term protection and full documentation. You are paying for a preservation outcome that protects the vehicle for years, not a quick surface clean.
Is dry ice blasting cheaper than sandblasting?
Not always on the headline figure, but the comparison is rarely like-for-like. Sandblasting equipment and media are usually cheaper, and the media can often be stored or reused. Dry ice is more expensive to produce, has to be kept cold and constantly sublimates, so it cannot be stored in the same way.
Dry ice blasting also uses specialist machinery, high-capacity compressors and trained operators, which makes the setup far more expensive than a typical abrasive blasting system. On a vehicle, it can also reduce the need for unnecessary dismantling because there is no spent grit to clean out of seams, cavities and hidden areas afterwards.
So while sandblasting may look cheaper at first, dry ice usually represents better long-term value for a vehicle you intend to preserve – especially where original finishes, sound metal and complex assemblies need protecting.
Can I hire a dry ice blaster or do it myself?
Hire machines exist, but the equipment is expensive to run, the dry ice has to be sourced and used quickly, and results depend heavily on operator technique around brake lines, looms, sensors and cavities. Most owners find a one-off DIY hire costs more than expected and risks patchy results or damage. For a preservation outcome on a car you care about, a trained operator with the right machine is almost always the safer route.
Service Areas: Oxfordshire
Where is IceBlastPro based in Oxfordshire?
Our workshop is at Unit 3, White Horse Business Park, Stanford in the Vale, Oxfordshire, SN7 8NY – just outside Faringdon in the Vale of White Horse, in the south-west of the county. All work is carried out here by appointment rather than as a mobile service.
Do you offer dry ice blasting near Oxford?
Yes. We are around 20 miles south-west of Oxford and regularly work on vehicles from Oxford, Abingdon, Witney, Wantage and the wider county. The vehicle comes to our Stanford in the Vale workshop, where we have the access, equipment and controlled environment the work needs.
Do I need to bring the vehicle to the workshop?
Underbody work is done at the workshop, so the vehicle does need to come to us. Proper preservation means raising the car, removing wheels, liners and undertrays where required, and documenting the underside – none of which can be done well on a driveway. You are welcome to drop the car off by arrangement.
Can you collect or deliver vehicles?
Collection and delivery may be available by arrangement, depending on the vehicle, timing and location. Many local owners simply drop the car off and collect it once the work is complete. Get in touch and we will talk through the options for your vehicle.
What types of vehicles do you work on?
Classic, performance, prestige, collector and well-kept everyday vehicles, as well as 4x4s. The common thread is owners who want the underside properly cleaned, inspected, treated and protected rather than simply washed. We treat each car on its own condition rather than to a fixed template.
Is dry ice blasting suitable for underbody rust treatment?
Dry ice blasting is the cleaning stage – it removes loose surface oxidation, grime and old contamination so the true condition of the metal is visible. Active corrosion is then stabilised and treated as a separate stage, and the correct protection system is applied. Cleaning, treating and protecting together is what makes the result last.
Service Areas: Cotswolds
Do you serve customers from the Cotswolds?
Yes. We regularly work on classic, prestige and collector vehicles owned across the Cotswolds. Our workshop is in Stanford in the Vale, just south of the Cotswolds in neighbouring Oxfordshire, so for many owners we are a short and easy run – and the standard of work is worth the journey.
Is the work carried out in the Cotswolds?
No – all work is carried out at our specialist Oxfordshire workshop near Faringdon, not as a mobile service in the Cotswolds. Underbody preservation needs ramps, proper access and a controlled environment to be done well, which is why it is workshop-based rather than carried out on a driveway.
Can you collect a classic car from the Cotswolds?
Collection and delivery may be available by arrangement, depending on the vehicle, timing and location. For valued classics we can talk through the safest way to get the car to us, including enclosed transport where appropriate. Many owners prefer to bring the car themselves and see the workshop.
Is dry ice blasting safe for classic cars?
Yes – it is one of the gentlest effective methods for a classic underside. There is no water and no grit, so it does not erode metal, force moisture into seams or strip sound original finishes. It lifts loose grime, surface oxidation and old failed coatings while leaving solid material intact, which is exactly what an original car needs.
Should I protect a classic car before rust appears?
Ideally, yes. The best time to preserve an underside is while the metal is still sound – before corrosion takes hold under old underseal or in the cavities. Cleaning, documenting and protecting a healthy underside is far cheaper and less invasive than dealing with structural rust later, and it keeps the car original.
Can you remove old underseal?
Yes. Old, cracked or poorly applied underseal often traps moisture against the metal and hides corrosion underneath. We can remove failed coatings to reveal the true condition of the underside, treat anything we find, and reprotect with a system suited to how the car is used and stored.
Service Areas: London
Do you offer dry ice blasting for London customers?
Yes. We work with London-based owners of classic, performance, prestige and collector vehicles. The work is carried out at our specialist Oxfordshire workshop rather than as a mobile service in London, because proper underbody preservation needs ramps, full access and a controlled environment.
Is your workshop in London?
No. IceBlastPro does not have a London workshop or branch. Our single workshop is in Stanford in the Vale, near Faringdon, Oxfordshire. London customers either bring the vehicle to us or arrange collection and delivery – all the work happens at the Oxfordshire workshop.
Can you collect a vehicle from London?
Collection and delivery may be available by arrangement, depending on the vehicle, timing, insurance and transport requirements. For high-value cars we can discuss enclosed transport. Many London owners prefer to drive the car to us, see the workshop and discuss the project in person.
Is this suitable for high-value or collector cars?
Very much so – it is the kind of car we are built around. Dry ice cleaning is non-abrasive and water-free, the work is inspection-led, and every stage is documented with photos and video for the car's history file. That record is exactly what owners of high-value and collector cars want.
How long does the process take?
It depends on the vehicle and the scope of work, from a focused clean and protect through to a full strip, treat and preserve programme. We confirm the likely timescale when we scope the job so you can plan around it – and we never rush the inspection, treatment or protection stages.
Can you provide photos and videos of the underside?
Yes – it is standard on every project. We photograph and film the underside through inspection, blasting, treatment and protection, so you can see exactly what was found and what was done. For owners who cannot be at the workshop, that documentation is how you stay fully informed.
Service Areas: Across the UK
Do customers travel from across the UK?
Yes. While many of our customers are from Oxfordshire and the surrounding counties, owners also travel from much further afield because underbody preservation done properly is a specialist service. For the right work, owners are happy to make the journey or arrange transport.
Can you collect vehicles from further away?
Collection and delivery may be available by arrangement, depending on the vehicle, timing and project scope. For cars travelling a long way, we can talk through enclosed transport options. Many owners choose to bring the car themselves so they can see the workshop and discuss the work.
Do you work on vehicles from the North of England?
Yes – distance is not a barrier when the work is specialist. We work on vehicles from across the UK, including the North of England, with the vehicle treated at our Oxfordshire workshop. Get in touch and we will talk through timing, drop-off and any transport arrangements.
Is the work worth travelling for?
Owners tell us it is. The difference is a joined-up specialist process – inspection, dry ice cleaning, rust treatment and the correct protection, all under one roof and fully documented – rather than a basic underseal job. For a car you intend to keep, that standard and that record are worth the journey.
How long will the vehicle need to stay?
It depends on the vehicle and the scope of work – from a focused clean and protect to a full strip, treat and preserve programme. We confirm the likely duration when we scope the job so you can plan the trip and collection around it. We never rush the treatment or protection stages.
Do you provide photos and videos of the work?
Yes, on every project. We document the underside through inspection, blasting, treatment and protection with photos and video. For owners who have travelled or arranged transport and cannot be at the workshop, that record is how you see exactly what was found and done.
