DPF (Diesel Particulate Filter) cleaning
I added a page to the website of a client (Allied Automotive and Muffler) today announcing that they do DPF (Diesel Particulate Filter) cleaning. I had no idea what Diesel Particulate Filter cleaning was, so I had to look it up.
Apparently there is another filter that needs cleaning regularly to help protect the environment.
It is always interesting what one learns by doing websites for different sorts of businesses.
