    Getting ready to fire up the home ac unit. Years ago the local hardware store sold some stuff just called "Coil Cleaner" that you would squirt on the coils of the ac coils to clean it. The big box stores put that place out of business and I just got back from HD and they never heard of it.

    Just looking for a cleaner recommend to use on the coils? I've heard some household cleaners will damage the aluminum and copper in the unit.

    There's two kinds of coil cleaner, well actually three, one is acid based, the other two are alkaline based, but one is for the condensor (outdoor) coil and one is for the evaporator (indoor) coil

    The acid based condensor coil cleaner is pink, should be diluted per instructions,, and the alkaline based condensor coil is yellow, and the indoor cleaner is green

    Now that I have got it all confused, you can use Simple Green or car parts stores sell some purple cleaner

    But generally if there isn't a bunch of real thick dirt or grease on it water will wash it off clean enough to work fine, just don't use too much pressure and bend the fins

    Been doing this stuff for 36 years
