Did not address the major question I had (got that info from a colleague). But it will be useful for other questions, I'm certain!

I've read the bad reviews on this....about wearing off, leaving a residue, and so on....but I LOVE this stuff. I love a shiny floor and I tried regular wax on my kitchen floor, but it left spots and wouldn't dry evenly. I had to remove it. I searched and searched and found this on amazon.com, bought it, and applied it to my floor. WOW!!! I love looking at my shiny floor. I have a puppy that is indoor puppy pad trained and her food dish, water dish and puppy pad are all in the kitchen....the pad is at the end in a corner where you can't see it but she will sometimes drip after going and always drips after getting a drink. I have a Swiffer Duster Mop but use an old washrag on it instead of buying the refills and I just dampen it and wipe up the floor. If it need a deeper cleaning, I just spray a PineSol mix, Windex or Kaboom on it and wipe the whole floor. NONE of the finish has worn off, there are no spots or uneven marks and it just looks wonderful. I also did my bathroom floor and it's so easy to clean now and shines just as well even if drips stay on the floor after a shower before I see them. The drips have never left any spots. It puts on a great protective finish. This bottle will last a long time but I will purchase it again when I run out. I have nothing but good to say about this....MUCH better than wax!!!
