Both fans are running.
That foam cleaner for the inside probably is also a disinfectant and odor neutralizer. Any cleaner that doesn't require flushing, wiping, or vacuuming, probably isn't really cleaning anything...
For the inside--I'd remove the filter, wash it (always wash them in "reverse" meaning the side of the filter that faces the inside of the unit is the side that should get the water sprayed on it to start. I'd use my best vacuum, maybe a shop vac if you have or can borrow on... this would be especially needed if you've got pets/etc...
For the outside--I guess flushing it w/ a hose is OK, I've personally never done that, because I've never found that much dirt or debris really got in there, but I suppose if you have trees/etc around and you live the units in place year round it might get bad. Just be careful about where you are putting the water and how much--you don't want to risk having it rush into the house or other parts of the unit. It's designed to handle water, but still worth being careful.
If you have bent fins on either the interior and exterior parts, you can buy a tool to straighten them (or use a credit card or something stiff). I sort of doubt bent fins would cause your symptom, but if you've got a LOT of bent fins maybe it would?
