AC coil cleaner
Hi
My friend told me to buy some coil cleaner for my AC after he saw how dirty it is. Is there any type you prefer or is simply good, better than others? I'd rather ask stupid easy question than pay for product that simply doesnt work.
Also should I clean evap coil as well? If yes then how?
I attached photos, there is no normal opening. Should I cut it this aluminum duct to create opening?
I found online cleaners for evap which are "no rinse".
Let me know what do you think, if it is needed.

The home improvement stores carry coil cleaner. You can get liquid or spray.
The spray can be a little easier to use. You'll need 1-1/2 cans. One is not enough.
Rinse well to remove all cleaner as it's corrosive.
It's not always easy to get access to the evaporator coil. I see a patch near the coil.
Have you tried removing that to see what it allows you access to ?

Yeah I would think your coil would be accessed from that panel with the edges covered in foil tape. Have some more foil tape on hand to close it back up once you're done.

oh yeah, the patch. It was used to clean the ducts but maybe it is enough to put my hand and spray coil. How exactly does this "no rinse" product works? foam dissappears? because Im guessing there us no place for the dirty corrosive water to drain...
One of the stores sell 1gal bottle, I will buy it so I can clean it for the 3 following summers.

There is a drain pan but it can be hard to get water in to flush the coil.
The coil cleaner is acidic. It shouldn't be used every year outside.
Use it one year to degrease the coil and then just use plain water the next time to clean the coil,
