Quick answer
Car carbon cleaning prices can range from around £50/$70 for a basic service to over £200/$300 for more intensive methods. DIY kits may cost significantly less but require hands-on effort.
Detailed answer
If you choose a professional car carbon cleaning service, expect varied quotes depending on your location, car model, and deposit severity. Some mechanics use straightforward chemical treatments, while others have specialised hardware—like walnut blasting or hydrogen machines—which can drive up the cost. In a thorough job, they may remove the intake manifold, clean valves directly, and reassemble. This labour-intensive approach often yields dramatic improvements for cars suffering serious buildup, but it also raises the price tag. For minor issues or routine maintenance, you could opt for an affordable DIY additive or spray, though its efficacy might be limited if the carbon has become hardened. Assess your car’s symptoms, your willingness to do some elbow-grease work, and your budget to decide the best route. If done properly, even a mid-range service can pay off in better performance and potentially fewer future repairs.
