Cleaning Outdoor Heat Pump

[notmine]

I’m planning on using my garden hose to spray the the coils of my heat pump from the inside spraying outwards.
I do understand that u need to be careful not to damage the fins when doing this.
What I’m more concerned about is can I be getting things wet that shouldn’t be getting wet and causing issues?
Plan on spraying with water only and no chemicals. Has anyone done this and did you have any problems afterwards??

you need cleaner. they make cleaner just for that. no it wont hurt anything. they make foam devices just for it also.

They live outdoors, so water is fine. I wouldnt open up the electrical enclosure and wash that down, though.

You don't need cleaner if it isn't terribly dirty. Water can be plenty in many cases

They make no rinse cleaners, spray on and the condensation does the rest. I like the type you spray off.

Those are for the indoor coil, afaik. The outdoor unit won't have condensation on it in the summer.

Don't spray the fan motor little mist is fine. Don't like coil cleaner unless the oil on the coil. Fins are aluminum after use cleaner the fins turn shiny taking the oxidation off and little more. After cleaning them a few times fins get thinner with each cleaning and lose strength.

Thanks for the valued feedback

For AC/minisplit coil cleaning, use a neutral PH cleaner or you damage the coil surface over time, many wood floor cleaners are neutral PH. The product SDS should give the PH of the product, 7 is neutral. Unless SDS states a PH of 7 (or a bit more like 7.2) do not trust it, some companies state neutral then the specs show between a PH of 6.5-8.5 .
