DPF DIESEL PARTICULATE FILTER CLEANER: Use Redex DPF Cleaner Diesel, the specialist diesel additive and cleaner, to keep your Diesel Particulate Filter (DPF) clean - this will prevent costly repairs and a lot of stress. CLEARS SOOT FAST: Our DPF Cleaner is designed to remove the soot that builds up in your DPF by lowering the temperature at which it burns - this means that more soot will burn off without you having to get your engine very hot. KEEP ON TOP OF YOUR DPF CLEANING: If you want to maintain your car’s DPF, so that the warning light never comes on, try adding a shot of Redex DPF Cleaner to your car with every 2-3 tanks of fuel. HOW TO USE: Pour the Redex DPF Cleaner directly into your fuel tank. Thanks to our specially designed bottle, you can add the product directly to your car through the fuel filler cap, where it will mix with diesel and circulate through the system.
