What is the best evaporator coil cleaner?

- Mar 13, 2019-

When cleaning the evaporator, a small amount of neutral detergent can be added to the water, sprayed slowly with a small watering can, and then rinsed with water after heat. After cleaning the evaporator, a bottle of clean water can be poured onto the evaporator. If the outdoor drain pipe has smooth water flowing out, it indicates that the water receiving tray in the air conditioner is not blocked by dirt.
