The only problem is you have to
inspect it closely so you can see any dirt or dust build up clogging
the fins. Of course, if you decide to spray it with a water hose, don't
use a high pressure stream because you can bend the thin aluminum fins
covered by the louvered cover, always use a gentle fan spray. ^_^

They sell a product for cleaning the fins. Spray it on, allow a few
minutes, then rinse with a hose.

Does that stuff really work? A guy said to me the spray foams up and
pushes dirt and cooties out when rinsed.

Yeah / Nay

I use just a hose.
