We clean them annually and inspect the HUG controls and injection systems. We started off cleaning them based on hours but found some engines with less hours had more ash then engines with higher hours.

We do the cleaning ourselves and use a combination of high volume air nozzles from Exair and a vacuum cleaner. You should see some major improvement if you clean them.
