I have an '06D with 24,500 mi. I recently had some coolant leakage around the water pump area. But now I have some pink and white stains on the black powder coat on the engine. Any idea on how to remove them? I thought they might be calcium deposits, so i tried some vinegar. That didn't work. I may try some CLR next, but I don't want to harm the paint or aluminum.
How about back to black (usually used on black plastic)?
