Reduce carbon buildup, improve fuel efficiency and restore engine performance in your hybrid – without dismantling the engine. Open 9am – 6pm, closed on Sunday.
Hybrid cars switch their petrol engine on and off constantly. In Singapore’s stop-start traffic the engine often runs in short bursts and rarely reaches full operating temperature, so fuel does not burn completely. Over time this leaves carbon deposits on the intake valves, pistons and combustion chambers.
At CarbonClean.sg, our hydrogen engine carbon cleaning treatment helps hybrid owners reduce carbon buildup, improve fuel efficiency and restore engine performance – without dismantling the engine.






A hydrogen-oxygen gas is fed into the engine through the air intake while it runs. Because hydrogen burns faster and hotter than petrol, combustion becomes more complete, and the carbon (soot) stuck to the engine’s internal surfaces gradually breaks down and leaves through the exhaust.
Results vary with each car’s condition.








Yes. A hybrid’s petrol engine starts and stops frequently and often runs for short periods, so it may not reach full operating temperature. This leads to incomplete combustion and carbon deposits on the valves, pistons and combustion chambers.
Yes, when it is done correctly. Hydrogen is non-corrosive and reacts with carbon deposits without harming the metal, rubber or plastic parts of the engine.
It depends on the vehicle and how much carbon has built up. Some treatments take around 30 minutes to an hour, while others take longer.
It may, if carbon deposits are affecting combustion and engine performance. Results vary with each car’s condition, and carbon cleaning will not help if carbon buildup is not the cause of high fuel consumption.
No. The treatment works on the petrol engine’s intake and combustion chambers. It does not touch the hybrid battery or high-voltage system.
We treat a wide range of Japanese, Korean and European hybrids, including Toyota, Honda, Lexus, Kia, Hyundai, Mercedes-Benz, BMW, Audi and Volkswagen.
Hybrid carbon cleaning is available at our Serangoon Garden, Bukit Batok and Upper Thomson workshops, by appointment. WhatsApp +65 6264 3832 to book.
By appointment, Mon–Sat 9am–6pm. WhatsApp us your car model and we’ll get you booked in.
