Why You Need Redex DPF Cleaner

If you have a modern diesel-powered car, chances are it has DPF installed. However, all DPF’s have a limited capacity to capture soot expelled from the engine. Leave the DPF unattended and you will likely suffer from poor performance, warning lights and the possibility of breakdowns and expensive engine damage.

You want to avoid the breakdowns and the embarrassment but without the costly garage bills. For a modest outlay, Redex DPF cleaner, added to your fuel tank at your next fill-up, could not only solve existing issues but also prevent future complications.

Redex DPF Cleaner in Detail

Redex’s DPF fluid works by lowering the temperature at which expelled soot can be passed through your car’s exhaust system. Regular build-ups require continuous, high speed driving to reach high enough temperatures to remove, if they can be removed at all via driving alone. Redex’s product lowers that temperature, enabling the soot to be removed, cleaning the DPF during regular driving.


As well as relieving you of the stress and worry of a possible breakdown, the DPF cleaner can also bring some everyday benefits. Having an optimised flow through your exhaust allows your engine to run efficiently. This could give benefits of increased fuel economy, improved performance and effortless starting.

Redex as a brand is also highly regarded by thousands of consumers. As a result, their products can be found easily via the internet, at your local auto store and is even carried by some supermarkets.
