Read the label......they will usually tell you if it is okay for aluminum, or not. I used to use Simple Green before I found out about the aluminum issue. Even though I rinse and rinse and rinse, I do like to let whatever I am using sit for a few minutes to work before rinsing it and the gunk it has loosened off. Usually I can find some sort of citrus based cleaner of which most seem to be okay for aluminum applications (Napa, Autozone, O'Reilley's, etc.).

On coolant I do use the Detroit Diesel product, Power Cool which happens to be reddish i color.
