Best method/solvents for cleaning evaporator coils

HVAC outside condenser unit

I understand now that I had a terminology problem and what you were calling an evap coil is what I've always called the "A-coil." Mine is in my garage but drains condensate into a pan and then drains into where ever:rolleyes: but i didn't have any problem using low pressure water after using coil cleaner.
Link above (actually inside and outside coils) is something I posted back in the day. You may find it useful and ETLS made some posts on it, he's the expert.
