Original Commentary
It's the same stuff that goes into "tropical" flavored iced tea to give it that fresh scent... and slight foam.

Modern Commentary
I think it was Panera that had that tea.

But yeah, that spray won't get your stuff any cleaner, but it'll get your stuff smelling cleaner which is almost as good.

Lemon Technology sells this stuff for industrial use. I've generally pictured it in 50-gallon drums but have not done enough research to verify how they are sold in real life. I'm sure some fragrance chemicals are sold by the pint, but those would probably be the kind where you just need a few drops in a whole batch of the product.
What I'm trying to say is that I have no idea why the company would have a spray bottle like this nor how Brisbane got it.- Terrence
