The ONLY Simple Green product that can be safely used on aluminum surfaces is "Extreme Simple Green", which is specifically made NOT to cause corrosion on aluminum. I agree that your radiator needs to be cleaned, but use the right product and not something that can etch away at your aluminum fins if not thoroughly rinsed off completely. The standard Simple Green concentrate must not be left on any aluminum surface for more than 10 minutes and if not completely rinsed off, which is difficult to determine with a radiator, can accelerate corrosion.
good comment, but where do you buy it?
