Bill, I assume you're referring to the Mira Clean #1 link above. I did a bit of checking online and it looks like there is a building place in a city not too far from where I live that sells Miracle products so I'll have to give them a call. Your link says that the product only has a shelf life of one year so it'll have to buy accordingly. I used the ST Revitalizer this weekend and it's pretty easy to use in our smallest bathroom and seemed to clean the floor well without any steaking, unpleasant or chemically smell, etc. Thanks again!

Now I'm more confused than ever. Do you mean that if it was sealed before it shouldn't be done again until the old sealer is removed? What happens if you reseal something that has been sealed with a different product? Do you spray acetone on, wipe it on? I'm not a technical person at all and I have tried to read the websites on caring for stone and I am really totally learning disable on these types of subjects because I can't follow at at what they are trying to say. Anything you can do to help me understand this will be greatly appreciated.

You should try this in the bathroom forum, lots of tile guys over there.

You might want to invest in a canister model steam cleaner. It would clean without any chemicals. I have never had marble tiles, but I like the StoneTech line of products and they make a stone and marble cleaner: Stone and marble cleaner
