The new DPF/GPF Cleaner from LIQUI MOLY allows particulate filters to be cleaned thoroughly without removal. This can provide a simple and cost effective solution for workshops and vehicle owners.


Fast, convenient and cost-effective, Diesel Particulate Filter /Gasoline Particulate Filter Cleaner, from the German lubricant specialist can save time and keep vehicles on the road. 

Particle filters are mandatory by law and essential for reducing emissions. However, in some conditions and particularly on vehicles doing shot journeys, they can malfunctions as they become clogged with soot. This will result in higher fuel consumption, fault messages in the engine management system and, in the worst case, damage resulting in expensive repairs. The new DPF/GPF Cleaner from LIQUI MOLY dissolves the hardened soot layer on the surface of the filter and enables active regeneration while driving or using a vehicle diagnostic device, without having to remove the filter.

The additive specialist already offers a proven probe solution that efficiently lifts even stubborn residues with 1.5 litres of cleaning fluid and eight bar pressure. This method remains the most effective choice for heavily clogged filters. The new cleaner in a can offers a quicker and easier alternative. It is an economical solution for many applications that can be used without additional equipment.

“Similar to our A/C System Cleaner, with which we serve different market segments, we are creating an ideal addition to our existing portfolio with the new DPF/GPF Cleaner. This allows workshops to flexibly choose the right solution for their needs.” explains David Kaiser, Head of the Research & Development department at LIQUI MOLY.

The new product is specially aimed at workshops and perfectly complements the existing professional portfolio of probes, pressure guns and cleaners. 

The new DPF/GPF Cleaner is available now from LIQUI MOLY stockists.
