    We use Nu-Brite as well, everyone has their own prefferrence as to wich one according to job at hand. I use the purple on outdoor coils, and the green slf rinsing on indoor coils. Both work well and in my area we get a lot of oily residue as well as cotton wood. I do need to seperate the two coils to get the build up from in between them. Rinsing with a hose and spray nossil. Seen too many finns closed due to high pressure!

    Black Max. Do not get it on you. It is non acidic but will still make you do the ant dance. I get it at Appliance parts here on the Gulf Coast in Ms.

    Water is my first choice. The manuals for most, if not all, of the units we install read something like this:

    I hardly ever use condenser coil cleaner, usually only if there is something on the coil that water alone won't remove.
    When I do use a cleaner, it is usually Nu-Calgon nu bright, or alka-bright.
    I was given a sample of Black Max at a trade show a few weeks ago, but haven't had opportunity to try it yet.
    If more government is the answer, then it's a really stupid question.
