The diesel particulate filter, together with the catalytic converter of used cars, becomes heavily soiled. As a result, fuel consumption increases, while the power and dynamics of the car decreases. Solves the problem of cleaning the filter. In car services, this is done in haste, removing only part of the soot. With a few hours of free time, it’s best to do the filter cleaning yourself.

What you need:

  • Particulate filter cleaner;
  • plastic container;
  • high pressure washer.

Filter cleaning process

The filter can only be cleaned properly by removing it from the car. We simply disconnect the sensors and unscrew it from the exhaust system. Then open the filter by loosening the clamping band or bolts if you have a different design.

This is a caustic substance, so it is better not to inhale the fumes from it. The poured catalyst is left to deoxidize in the cleaner for the time specified in the instructions for the composition used.

After the specified time, you need to drain the cleaner. Many of these compositions can be defended, and after the precipitation of the sediment, then reused a couple more times. After the purifier, the catalyst is washed with water.
