Is there anything, other than long runs, that can clean a DPF?

What year were DPFs introduced by Ford and Vauxhall. Also is there anything out there that can really clean them, apart from long drives?
Every diesel had to have a DPF from January 2011 to meet EU5. Many larger diesel engines (1.6 up) needed them to meet EU4 before that, but some small 1.1 - 1.5 diesels met EU4 without them. They actively regenerate using the car's fuel every 200 - 300 miles and that clears soot, but they all tend to fill up with ash from around 80,000 miles. They can be cleaned by the Ceramex process.
