A machine, a van, and your driveway.
We remove the carbon deposits that build up inside every engine — without taking anything apart, without harsh chemicals, and without you going anywhere. Here is exactly how it works and what it does.
How hydrogen carbon cleaning works
It sounds exotic. The principle is genuinely simple.
1. Distilled water becomes gas
The machine passes a current through distilled water and splits it into hydrogen and oxygen. That is all it produces — no solvents, no additives, nothing that stays behind in the engine.
2. The gas goes into the intake
We connect a feed to the air intake and the engine draws the gas in on its own while it idles. Output is matched to your engine size, so a 1.0-litre city car and a 3.0 V6 each get an appropriate dose.
3. Combustion does the work
Hydrogen burns hot and fast. Introduced into the combustion chamber it helps break down the hard carbon that has baked onto valves, injector tips and piston crowns over tens of thousands of miles.
4. The carbon leaves
Loosened deposits pass out through the exhaust as the engine runs. You will often see the exhaust note clean up during the cycle. Then you take it for a decent run to finish the job.
What actually gets cleaned
The gas follows the same path the air does, so it reaches the places air reaches.
- Inlet tract and throttle body
- Intake valves and valve seats
- Injector tips and spray faces
- Combustion chambers and piston crowns
- EGR valve and EGR passages
- Turbocharger vanes and housing
- Exhaust ports and the front of the exhaust system
- Sensors in the gas path, including lambda sensors
What it will not do
We would rather you booked with realistic expectations than felt sold to.
- It will not restore compression on a mechanically worn engine
- It will not repair a failed EGR valve, turbo or injector
- It will not unblock a DPF that is already fully loaded
- It will not fix a misfire caused by coils, plugs or wiring
- It will not clear a warning light with a mechanical root cause
- It will not add horsepower beyond what the engine originally had
If we look at your car and think the money is better spent elsewhere, we will tell you on the spot. Read our piece on the risks and the myths we would rather debunk.
What happens when we turn up
We arrive and set up
Van parked nearby, machine on the ground or the tailgate. No mains power needed and nothing goes on your drive that shouldn't.
Quick look and a chat
Bonnet up, a look at the engine and a couple of questions about how it drives. If we spot something that needs a garage, we say so.
The cycle runs
Engine idles, gas is fed to the intake, output matched to engine size. Roughly an hour for a basic clean, up to two for a deep clean.
Handover
We disconnect, tidy up, tell you what we saw, hand you the invoice and receipt, and recommend a good long run to finish it off.
Cars, vans, 4x4s, hybrids
Petrol, diesel and hybrid. If it has a combustion engine and we can get to the intake, we can clean it.
Vans and light commercials
Working vans build carbon faster than anything. We can work around your jobs, including early or late.
Taxi and private hire
Huge annual mileage, endless idling and short fares. The fastest build-up we see on any vehicle.
Hybrids
The engine starts, runs cold and stops again. That cycle is harder on deposits than most people expect.
High-mileage cars
150,000 miles is not too far gone — but expectations should be set properly. Here is what to expect.
Small fleets
Scheduled cleans keep vehicles out of the garage. Talk to us about doing several in one visit.
Motorhomes and campers
Long layups and short shakedown runs are a bad combination. Best done before the season starts.
Book it in and forget about it
Basic clean £99. Deep clean £149. No call-out fee anywhere in the North East, and an invoice for your service file every time.
