Without knowing what you are cleaning I found that Simple green has a suggestion link categorizing the intended purpose of the product .

I for one am amazed, how this product has changed over the years. I stumbled onto it about 1980, looking for a cleaner to use for my bike. They had one mix, it was safe on paint, did not kill the grass and did one hell of a job keeping the motor and all the aluminum cleaned up

Note: Purple Power not for aluminum
