Ok here it goes. I am sorta neurotic when it comes to simple green. Some guy many months ago posted that simple green had some agents that could alter plastic.
I used simple green for quite awhile. I ran out and never bought it again and have been using Kal Guard degreaser. Now the neurotic part. I have broken far less plastics now that I have not used it in quite some time.
I know it sounds crazy and there is probably nothing wrong with simple green but I am not going to find out. I know many people who use it and love it. In fact it does a really good clean job.
