Cleaning air conditioner coils
I remember reading about spraying something on coils before hosing down for cleaning and can not remember what. Any ideas thanks. Frank.

Coil cleaner is not cheap. 409 and elbow grease. I used a $1 throw away paint brush cut off half and a hose with a sprayer on it. Plastic on the floor and towels around the sides. Spray, brush, rinse. Repeat as necessary.
