Caveat to using simple green on your coils

From the simple green website:
However, caution and common sense must be used: aluminum is a soft metal that easily corrodes with unprotected exposure to water. The aqueous-base and alkalinity of Simple Green All-Purpose Cleaner can accelerate the corrosion process. Therefore, contact times for unprotected or unpainted aluminum surfaces should be kept as brief as the job will allow - never for more than 10 minutes.
In short don't use too much don't let it sit too long and rinse really well. Or go buy yourself some purpose made air conditioner coil cleaner

I heard Dawn is preferred. Used it on my mini split a few weeks ago.

Garden hose water without spray nozzle from inside unit should be just fine

The AC guy that came to my house today said not to use any of these cleaning products, just straight water.

I would never have that do any work at my house.
Using any dish washing product [ie. Dawn soap] will only get part of the dirt off. To get the coils clean, you need a product made to clean A/C coils. When you spray it on the coils, it will start foaming to remove the dirt/oil from the surface.
Be carful to only spray the rinse water straight at the fins. Spraying at an angle can bend the fins and this will block air flow to the cooling coils.

There are many purpose made products for this type of cleaning that are safe for aluminum.
I like Tri-powr HD from Nu-Calgon. Can be used for both condenser and evaporator. Mix 10:1 as a "no-rinse" evaporator coil cleaner.
Water alone ain't going to get it. You need an emulsifier and surfactant to help get the crud off.
Now yes, it the thing is plugged solid and hasn't been cleaned in 3 years getting all the bulk solids off with water alone will do wonders, but it's not a full cleaning.
Also, only a hack tries to clean the condenser without removing the top cover and side panels. Do it right if you're going to do it.
