Pros: does clean, smell isn't bad, cheap cost
Cons: cleaning power is quite low, smell isn't pleasant, lower value to match lower price
I first ran into SimpleGreen products in the Army as they were ordered due to their low cost. Later I tried them in my own homes... never have I been impressed with Simple Green.
It will clean, but vinegar spray works better in my experience. It's only a notch or two up from just using water, honestly.
It's smell is not horrible but still a bit unpleasant... and leaves a cloying tone in the air around where it was used for a while.
The cost is low, but I found it very much a case of "getting what you paid for". -And as said, there are other cheaper and better-cleaning options available just in your cooking supplies.
If you're in a crunch and need a large amount of cheap cleanser, as we did in the Army, then this stuff would be a fair pick. But if you want it for normal daily tidying at home, I'd suggest saving money by mixing your own cleaner up or splurge a little on something that gives you more than your money's worth.
