the master technician who came out to service (clean) my walk-in cooler was 255 an hour and his helper was 150 an hour. after all that, my evaporator was corroded and 5k for replacement. after paying almost 6k for it, I did learn something I didn't know as a restaurant owner.... he schooled me on the acidity from all the marinated food cause corrosive particulates in air, so I need to wash down the evaporator coil more often.
Washing the coils regularly to get rid of grease, dust, dirt, tree sap, bugs, bird poop, all the normal stuff that accumulates on an outside unit is good preventative maintenance. Inside units in a restaurant usually benefit from an actual coil cleaning spray and agitation with a brush to clean it out, plus we treat the condensation pans with tablets to keep bacterial growth from taking place.
Have tried those and a wide variety of professionally available chemical solvents, when I was an HVAC technician. The deposits we have here in SoCal are resistant. I'm sure there's something out there that works, but none of the usual suspects that won't damage the delicate aluminum coils.
I think it’s great that you’re trying to clean up your AC condenser, but I feel like things would go a lot faster if you simply sprayed some type of chemical compound on all the coils all around, this would allow the chemical to burn all the water deposits out of the coils, that would ultimately allow airflow to be fully consistent again. Plus you would save hours of work and a head ache you don’t need. I hope this helps God bless and stay cool.✝️🙏🏻❄️🧊
I have yet to find a chemical spray that works effectively on the sort of hard water calcium deposits we have in Southern California... it's nasty stuff that only comes off with physical interaction.
Or why not just try to use an air blower and blow all the mineral deposits out the coils, and make sure you put on a Kn 95 mask that’s another idea as well that will probably go a lot faster than grinding it for hours.

Good to know! Thank you.
Happy to help!
Also can't you just use vinegar or C.L.R.?

So using distilled water should work, although it's more hassle than it is worth at that point. Or only use rainwater.

I think the mineral content varies considerably depending on location.
