Liquid Cleaning

  • Method: Soak the filter in a cleaning solution, then rinse.
  • Pros: Effective for both soot and ash; gentle on the filter.
  • Cons: Time-consuming; requires proper disposal of used solution.

Liquid cleaning involves submerging the DPF in a chemical solution that loosens both soot and ash.

After soaking for a prescribed period, the filter is rinsed with water to wash away the dislodged particles.

This method is thorough and gentle, making it suitable for filters with both soot and ash buildup. However, it requires significant time for soaking and drying, and proper disposal of the used solution is crucial for environmental safety.

Liquid cleaning is ideal for deep cleaning, especially when the filter has not been maintained regularly.
