How long is parked regeneration?

Can you clean a DPF with water?

Water in a DPF can set the soot/ash into concrete like substance, which will, in turn, ruin the DPF completely. Moreover, high-pressure water damages the cells inside the DPF. Ash removal through compressed air is not enough too. Per say, such a procedure for diesel cleaning service does more harm than good!
