There is something I love about a household cleaner that's packaging has been unchanged for the last 60+ years. To me that means the product actually works and they don't need a pretty label to make it sell. My Father-in-law recently introduced me to a new carpet cleaner that has "vintage" packaging. He loved it because it instantly removed a spot on his tie and left no soil marks....AMAZING. It's called FOLEX and it works!
Now what it IS made of I am not sure, but there are no odors or toxins (according to the label.) And it really leaves no sign of anything once you're done with it. I have tried it on a couple old stains on the carpet and couch and have yet to find something it won't remove. It's like a Magic Eraser in a bottle.
