A/C coil cleaner for radiator?

[Hoginedgewood]

Just thinking out loud, indoor cleaner I think is less aggressive than the cleaner for the outdoor unit and a gentle spray with a garden hose in the direction the opposite direction the dirt came from should be easy to access.

Foaming cleaners still need good rinsing after. Power wash not necessary, just thorough some foams alkaline base:lecturef_smilie: Is good if can only access one side of what your cleaning.
