What Is Engine Carbon Cleaning

carbon cleaning benefits

Prices from £89.99

The old fashioned way of removing carbon deposits from an engine is the equivalent to open heart surgery. It entails physically opening up the engine, using chemicals to loosen the carbon then scraping it away and removing it – an extremely laborious task (6-8 hours for a V8 engine) that is both costly and no efficient. Worst still generally a mechanic will only remove the carbon in and around the manifold, intake valves, and cylinder heads. However, much of the carbon deposits build-up later in the engine system e.g. around the EGR (Exhaust Gas Recirculation system and turbo and exhaust systems which also requires cleaning to fully restore your engine.

We are the Official UK Partner of the original and ground-breaking CarbonCleaning™ Hydrogen technology developed by PowerSystem of Lille, France in 2011. This unique advanced technology pumps and pulses hydrogen through the air intake system burning away the carbon deposits that prevent your engine from running smoothly. This remarkable system is suitable for any petrol, diesel or hybrid engine and has a proven ability to quickly and safely removing carbon build-up deposits from the whole engine system in just 30-45 minutes, the effects are immediate

High Standard of work

Just to say Matts work was to a high standard. He arrived early, focused on the task and did a great job. He completed all tasks required and ran a thorough check afterwards. Very reassuring! A genuine technician and people person. I have no concerns recommending Matt and his company.

I had Technician Cristian Nicolaie come…

I had Technician Cristian Nicolaie come to my home on Friday morning to diagnose and clean my DPF filter and remove carbon build-up from the engine. From the moment Cristian arrived, he was polite, friendly and professional. He asked me a few questions about the car, explained what he was going to do and talked me through the possible cause of the problem. He also gave me some really useful advice on how to help prevent the problem from happening again. Cristian carried out the work professionally and got the car back to normal. The diagnostic test afterwards showed that everything was working as it should. What made this even more important to me was that I was due to go away that day and had to tow my caravan. After speaking with Cristian, he gave me complete confidence that the car was going to be okay — and he certainly didn’t disappoint. I towed my caravan with no problems at all, and the car performed perfectly. I live in the BS15 area, and I would have absolutely no hesitation in recommending Cristian Nicolaie to anyone experiencing problems with their car. If the other technicians within the company have the same level of professionalism, knowledge and customer service as Cristian, then I would happily recommend the company as well.

Full Carbon Clean and remap

I had the pleasure of meeting Matt today. He was on time, gave great advice, honest feedback, great sense of humour - everything you would want from your technician. Never makes you feel stupid. Explained how the remap works. I'm only disappointed he didn't take a picture of my car for his portfolio.

Stage-3 Carbon Cleaning

Read more

As per our Stage-2 service plus our own branded chemical carbon cleaner solution that is designed to work in conjunction with the Hydrogen Carbon Cleaning. This unique chemical was developed when we realised that despite Hydrogen having some amazing results there are some limitations. Some carbon build-up retains moisture (mainly oily residues) which restricts the Hydrogen from interacting with the carbon as well as it could. This chemical is designed to burn as much of this oily residue away and dry out what is left so that thereafter the Hydrogen cleaning can produce even better results.

Recommended for: Petrol turbo and all diesel engines.

Depending on the level of service chosen our engine carbon cleaning service takes a total of 45-60 minutes.

Carbon cleaning is not as such a fix, its original purpose is cleaning as a preventative measure as carbon build-up is the root cause of 85% of the failure of components. If the component is simply clogged with carbon using not just our basic Hydrogen cleaning system but also our proprietary chemicals (that our competitors do not have access to) it is often possible to restore the operation of some components such as an EGR valve. However, if the component has failed then of course cleaning cannot fix something that has already failed. If you have an engine management system fault or a component diagnosis we recommend speaking to your local technician to discuss success ratios and options.

You cannot clean too much but we recommend preventative cleaning once a year, or every 10-12,000 miles – just like a regular oil change but for the air and fuel side of your engine - little and often is the key and as the saying goes… ‘An ounce of prevention is worth a pound of cure!

Certainly not. We are a worldwide brand with CE marked machines, operating in over 50 countries with 100’s of machines being used daily – never has there been an engine damaged from our engine carbon cleaning process.

We would not take any risks with your vehicle, so for piece of mind UKCC Auto Techs guarantee to you that all our technicians are trained to the highest standards and are independently fully insured.

No, this process is totally safe and untraceable.

No, our service cleans the inside of the engine, not the outside. You are looking for a service such as an engine steam cleaning, rather than engine carbon cleaning, which is something we do not offer.

Yes, we offer multi-service and multi-vehicle discounts.
