Help with Methanol Injection

[01RAM5.9]

Hey guys, my new-to-me 5.9 Cummins has the Snow methanol injection kit... Been doing some reading up on the unit and they say the nozzles need to be cleaned every so often, more so if a guy runs methanol WW fluid. Can someone give me some direction on how I should clean the nozzles when the time comes? Also, what is the approximate service intervals for these systems?

Best bet would b to contact Snow them selves.
