Be careful with Simple Green, I have heard it will damage aluminum.

Yes, I would be careful with the Simple Green. I had some in my garage years ago and my grandson decided to wash his dad's car. Used Simple Green on the wheels. Then I heard my son "blast off" when he went outside to check. You could see everywhere the detergent had and hadn't been - sort of discolored? the areas (some sort of reaction). I removed it from the garage and no longer keep it anywhere.
