Why Drivers Book Us

Cleaner Engines,

Smoother Drive

We’ve helped countless diesel and petrol engines run smoother, quieter, and cleaner with our
in-house hydrogen carbon cleaning service. The machine feeds pure hydrogen through
the intake and breaks down hard carbon on valves, injectors and EGRs—no tank additives, no parts
removed. The results? Sharper throttle response, fewer flat spots and lower emissions.

Call us on 07827533529 or book a clean online today.

Engine carbon cleaning strips built-up soot and deposits from the intake runners, injector tips, valve backs and EGR channels. Slow warm-ups, short supermarket runs, and urban stop-start driving let carbon bake hard, robbing power and lifting emissions. Our hydrogen machine feeds H₂ through the air stream, lifts that carbon at a controlled temperature, then lets the engine burn it away—no solvents in your tank, no dismantling required.

We focus on diesel vans, light trucks and turbo-petrol cars for drivers across Stoke-on-Trent, Staffordshire and Cheshire East. Dealer-grade diagnostics record AFR, misfire counts and exhaust back-pressure before we start; the same live data after the clean proves the difference. The process takes 45–60 minutes, restores crisp throttle response and often turns a past-fail opacity reading into an easy MOT pass.

Keeping the intake system clean also protects other parts. A clear EGR path prevents sticky valves, clean injector nozzles give a finer spray, and freer airflow helps the DPF regenerate at the right temperature. Book a slot at our Hanley garage, grab a coffee nearby, and drive away with a smoother idle, quicker spool and a cleaner burn for months to come.

Common Carbon Buildup

Cars We Clean Most

for Intake Carbon

City driving, short journeys, and turbo petrol engines are the biggest triggers for carbon build-up. We’re called out weekly to clean up rough idles, poor fuel economy, and limp-mode faults caused by soot coating the intake, EGR and valves. Below are some of the most common vehicles we service with our mobile engine carbon cleaning setup:

BMW 320i / 330i (Petrol)

Direct injection engines suffer heavy intake carbon on town drives. We restore throttle response and idle smoothness.

VW Golf 1.4 / 1.5 TSI

Short runs and turbo heat soak carbon up the valves — especially in start-stop traffic. Clean restores MPG and torque.

Ford EcoBoost Engines

1.0 and 1.5 EcoBoosts are known for valve carbon build-up. Hydrogen cleaning avoids expensive strip-down work.

Mercedes C220 / E220 CDI

Diesel swirl flaps and EGR passages clog with soot, causing sluggish drive and high idle revs. Mobile clean fixes both.

Vauxhall Astra / Insignia 1.6 CDTi

Low revs and town driving cause carbon layering across intake and EGR — resolved in 30 mins at your home.

Peugeot 1.6 BlueHDi

Known for intake restriction and turbo lag due to sticky carbon. Our hydrogen clean restores proper airflow.

Why Clean Your Engine?

Restore Performance, Improve Emissions, Drive Smoother

Over time, carbon builds up on your intake valves, injectors, EGR system and combustion chamber — especially in stop-start driving or short trips. A hydrogen-based engine carbon clean breaks that down, helping to restore lost power, smooth out idle, reduce turbo lag and cut harmful emissions. It’s a fast, way to breathe new life into your diesel or petrol engine without dismantling parts or adding fuel additives.

FAQ’s

Have Questions About Carbon Cleaning?

Real Answers for Real Engine Problems

What is engine carbon cleaning and how does it work?

Engine carbon cleaning removes built-up soot and carbon from your intake valves, EGR system, injectors, and combustion chambers. We use a hydrogen-based system that feeds clean gas into the air intake while the engine runs, breaking down baked-on deposits without dismantling any parts. It’s safe, fast, and done on your drive.

Does engine carbon cleaning really work?

Yes — when carbon buildup is the issue, you’ll often feel smoother idle, quicker throttle response, and reduced emissions. It won’t fix every fault, but it’s proven to help petrol and diesel engines suffering from sluggishness, vibration, or poor fuel economy due to carbon restriction.

What are the benefits of engine carbon cleaning?

Our customers often report a quieter engine, better low-end torque, less smoke from the exhaust, and lower MOT emissions. It’s also a great preventative measure for drivers doing mostly short trips or city mileage.

How often should you carbon clean your engine?

We recommend a clean every 15,000 to 25,000 miles — sooner if you drive mainly in town, idle a lot, or have a direct-injection petrol or turbo diesel engine. Frequent short trips can lead to faster carbon buildup.

Is engine carbon cleaning worth it for diesel cars?

Absolutely. Diesel engines, especially those with EGR valves and DPFs, are prone to carbon buildup. Cleaning helps restore airflow, reduce soot at the source, and prevent the kind of restriction that triggers limp mode or forces costly EGR replacements.

Can engine carbon cleaning damage my engine?

No — our hydrogen carbon cleaning method is non-invasive and safe for petrol and diesel engines. We don’t add chemicals to the fuel tank or remove any engine parts. It’s a low-risk service with high potential benefit.

How long does a carbon clean take?

Most mobile engine carbon cleans take 30–45 minutes once set up. We come to you, plug in, run the clean while the engine idles, and pack away — no need to visit a garage or wait in a queue.

How much does engine carbon cleaning cost in the UK?

Most hydrogen-based mobile carbon cleans range from £60 to £120 depending on engine size and vehicle type. We’ll quote you up front — no hidden charges. It’s often cheaper than replacing EGR valves or chasing poor emissions with parts swaps.
