Fully mobile across Otley and the surrounding West Yorkshire — we come to your home or workplace.

What's Included
Everything a hydrogen clean covers.
Every time your engine runs it leaves behind carbon — on the valves, in the intake, around the EGR and across the combustion chambers. Over thousands of miles that build-up restricts airflow, upsets the fuel-air mixture and makes the engine work harder for less. Our hydrogen carbon-cleaning process introduces a controlled hydrogen-rich gas into the air intake while the engine runs, breaking down and burning off those deposits so they exit through the exhaust. It's a non-invasive clean — no engine strip-down, no harsh chemicals poured into your oil — and because we're fully mobile, the whole job happens on your driveway or at your workplace.

Questions
Hydrogen Carbon Cleaning — FAQs
Will a carbon clean really make a difference?
On most vehicles with a few years and miles on them, yes — you'll typically notice sharper throttle response and smoother running. If your symptoms point to a mechanical fault rather than carbon, we'll tell you straight rather than take your money.
Is it safe for my engine?
Yes. The process uses hydrogen and oxygen produced from distilled water — there's nothing abrasive going through the engine and no chemicals added to your oil. It's a recognised, non-invasive cleaning method used on petrol and diesel engines alike.
How long does it take?
Most cars are done in around 30–60 minutes depending on engine size and how heavily carboned-up they are. We come to you, so there's no garage drop-off.
How often should I have it done?
As a guide, every 20,000–30,000 miles keeps things in good shape, or sooner if you do a lot of short, low-speed journeys that encourage carbon to build up.
