Yep ... there seems to be no problem with full-strength Simple Green if you don't soak your parts in it. I don't have a bottle of it here, but it seems to me that the label on the bottle also recommends that people do not soak things in Simple Green. Someone else can check that.
Any problems I've heard with Simple Green have been stories where someone has apparently left a chain or something soaking in it over the winter, and came back to find the chain or whatever it was half gone.
