Well, I am in a corner now on this one. I happen to believe in Simple green as I have used in in degreasing aluminum parts for spacecraft applications. If there had been any hydrocarbon residue we would have detected its effects in post processing x-rays, so I know this one works well for degreasing.

But my problem is with using terms such as "like". If simple green is shown to be effective and safe, then they ought to say "use Simple Green", and not say "use something like Simple Green".

In the retail stores there are a lot of cleaners pretendign to be "just like" some other cleaner. But retail cleaners are not supplied with MSDS or other ways of validating their composition. I prefer industrial materials which are carefully specified and repeatable from batch ot batch and year to year. If I use a material which is approved for use in nuclear applications, I know that its composition wil be stable from batch to batch. That is why I prefer them.

I was really harping on the lack of specification in the original quote rater than picking on Simple Green or even 409 (although I would NEVER use 409 inside my tank).
