How it works

What is Engine Carbon Clean?

Engine Carbon Clean is an efficient hydrogen process that removes carbon build-up in any internal combustion engine. The result is enhanced fuel efficiency, helping to save money on petrol or diesel bills and providing increased overall performance.

Our mobile carbon cleaning process is quick, thorough and easy to understand, without compromising quality. Engine Carbon Clean requires no dismantling of engine parts or using harmful chemical products.

Prior to starting the clean our technicians will connect their portable diagnostic device to your vehicle allowing them to establish the status of your vehicle in preparation for the clean. This is included as part of the service and could highlight any vehicle faults or items that may require attention.

Why does carbon build-up occur?

Carbon can build up within engines over time, with many petrol and diesel fuels having a low purity level, leading to a variety of detrimental issues in the long term, including:

  • Lower performance
  • Lower power
  • Higher emissions
  • Higher and more frequent replacement costs
  • Fuel inefficiency

When grouped, these problems can have a significant impact on your bills, as well as your time. Removing the carbon build-up with our efficient and mobile service is an effective way to tackle these issues.
