Any tips for cleaning cottonwood from the side fins on my Pentair heat pump? Vacuum? Water hose? I'm concerned about damaging the fins.

I'd use a vacuum. They also make a fin comb for straightening out deformed fins in case you need it. They're also good for cleaning fins too. They make different sizes so measure the distance fin to fin to be sure you get the one you need.
