Revolutionary hydrogen-powered engine decarbonisation. Non-invasive, safe, and effective — recommended every 30,000 miles.
HHO (Hydrogen-Hydrogen-Oxygen) carbon cleaning is a revolutionary, non-invasive process that uses hydrogen gas to safely remove carbon deposits from your engine's internal components. Unlike traditional chemical cleaners, HHO cleaning is completely safe for your engine and produces zero harmful byproducts.
We connect our HHO machine to your engine's air intake system.
The machine produces hydrogen and oxygen gas through electrolysis of distilled water.
The HHO gas is drawn into the engine, where high temperature converts it to steam that blasts away carbon deposits.
Your engine is carbon-free, running smoother, more efficiently, with restored performance.
Starting from £150 per session. Price varies by engine size. Contact us for a quote.
Removes carbon deposits from intake valves, pistons, and combustion chambers, restoring lost engine power.

Booked online in 2 minutes. Car was ready early. Couldn't be easier! The team were brilliant and explained everything clearly.
They showed me the worn parts before replacing anything. Total transparency — exactly what you want from a garage. Will definitely be back.
Fair price, honest team. I've been back three times now. Big Al's is the only garage I trust with my car. Highly recommend to everyone.
Finally a garage that texts updates without me having to chase. Great service, great price. My DPF issue was sorted same day!
Had my HHO carbon clean done here. The difference in how the engine runs is remarkable. Smoother, more responsive, better fuel economy. Worth every penny.
MOT passed first time. Friendly staff, clean workshop, and they didn't try to sell me anything I didn't need. Refreshing honesty from a local garage.
