Simple Green

[OrangePeel]

Is simple green safe to use at full concentrate, or should it be diluted for use on artwork.

I have never diluted it. But.....

I buy the gallon jug and dilute it per the directions for heavy cleaning typically. I have used it as concentrated too and it's been fine. When I was buying the spray bottle and using a lot less of it, I would fill it with water when it was half gone...it's still stronger than the heavy cleaning ratio.

Either way is fine.

Resurrecting this thread with a related question.  John - do you typically use regular Simple Green or concentrated Simple Green? 

I've had a time finding Simple Green. The closest Walmart only carries concentrated (and it's not in the grocery cleaning supplies, the automotive cleaning supplies, but on the bottom shelf near the plumming/electrical). I've heard Krogar carries it, but haven't found it.
