What is engine carbon cleaning?

Engine carbon cleaning is a form of preventative periodic maintenance, in which potentially harmful carbon deposits are removed from primary engine components. The most effective form of engine carbon cleaning utilises crushed walnut shells as an abrasive, which are hard enough to eliminate carbon deposits but will not cause any damage to the vehicle’s engine.

The walnut shells are blasted at the engine components at a high speed as part of a controlled procedure, which subsequently results in components free from carbon deposits and able to perform with optimum efficiency. Though engine carbon cleaning is traditionally more closely associated with high performance vehicles, it is nonetheless suitable for most types of cars and can prolong engine life. 

What is the best way to clean carbon & deposits from intake valves?

While there are various solvent-based products and DIY kits available, taking the manual approach cleaning is the most effective and complete way.  Unless you know exactly what you are doing, the best way to clean carbon from an engine is to organise professional blast cleaning with a team and experienced technicians.

This is because some of the solvent and other products routinely used to remove carbon deposits can cause serious and even irreparable damage, if used incorrectly. Professional carbon cleaning can enhance the performance, efficiency and lifespan of your engine – all of which stand to suffer if your engine is damaged through the improper use of carbon cleaning products.

Does carbon cleaning clean EGR?

One of the main benefits of professional carbon cleaning is the way in which it prevents wear and therefore extends the lifespan of some of your engine’s most expensive components. One of which being its exhaust gas recirculation (EGR) system, which can be maintained and kept in optimum working order with periodic carbon cleaning.

Periodic maintenance holds the key to long-term engine performance, reliability and cost-effective car ownership. The professional removal of harmful carbon deposits from your engine could save you the hassle and expense of much costlier repairs and component replacements in the future.

Does carbon clean DPF?

Over time, carbon deposits accumulate in various components of your engine and can cause a variety of performance issues. One of which being a blocked DPF, which can cause severe problems with reliability, engine performance, fuel-efficiency and even safety.

Carbon cleaning is a safe and effective way of keeping harmful carbon deposits in your engine to an absolute minimum. By cleaning your car’s engine of carbon deposits on a periodic basis, you’re less likely to face the problem of a blocked DPF due to the excessive accumulation of carbon.

Does carbon cleaning actually work?

The short answer is yes – carbon cleaning works.  However, it’s not the kind of engine maintenance procedure that’s going to make an immediate and noticeable difference to your car’s power or performance.

Carbon cleaning is instead a form of routine engine maintenance, ensuring the most critical components of your car’s engine are kept clean and in top working order. This ultimately contributes to the performance, fuel-efficiency and lifespan of your engine, negating the need for costly repairs and component replacements at a later date.
