Spray 9 is great!!! I caught on to it at a friend's motel in Hollover Beach,Fl.It kills all germs and gets out every bit of filth and dirt that might be clinging on to different serfaces from porcelain to Formica.When I bought my first bottle,I sprayed my cabinets which had been painted white and looked real dull. I couldn't believe the lines of white that were appearing as the spray ran down the surface!I mean you would have thought I had been smoking cigarettes 4 packs daily in my kitchen the way that stuf turned the dull, off white look to a blinding white!.ever since then, I have sworn by that and it's real hard to find. I usualy see it in the older ,traditional,local hardware stores.Never see it at Lowes or Homo Depot.It's real strong but not half as potent as bleach or amonia as far as the smells go.It sort of reminds me of the old Janitor in a Drum scent.One of the first appliances I used it on was a nevr used FRIGIDAIRE Dishmobile from 1962!It had faded and the turquoise color had dulled.after I appliad it and rubbed it in,the paper towels I whiped it with looked black!!I had to rinse it off to be able to use windex to finish off the cleaning. I was shocked,amazed and thrilled at the way that cleaner worked!.It is also good for spraying on stains on clothes! just spray the area where the stain is and add that piece to your wash.
