The answer is "maybe, maybe not, and maybe over time."

From what I have read, Rejuvenate is an acrylic polymer that can be removed with some ammoniated products, commercial grade citrus cleaners, or a commercial floor stripper. So there is nothing in the water of your steamer that is going to hurt the finish, but the heat is what is in question.

Some people have found that steam cleaning dulls the shine on their vinyl flooring. It appears to be a function of how much heat the finishing surface can handle.

I'd be careful. There was a post on gardenweb a while ago that said Rejuvenate put a beautiful shine on the floor but since it wasn't a hard enough finish, it ended up creating a smeary mess. I had a similar problem with QuickShine, and it was god-awful to remove. Also, it's possible the dullness of your tiles is due to reside left behind from other products over the years. I'd try a product from a flooring store (like Stone Tech products) designed to remove this build up, and then use the steam mop without any products whatsoever for a month. Then see how it looks...

Thanks for the replys. Actually, my floor isn't that old but it is a flat ( not shiney tile ) and I wanted to put a shine on it. The neighbors have the same tile & they used a poly product and it really made their tile smooth & glossy. However...they don't use a steam mop. I'm really undecided what to do. I wish someone would chime in that has used the rejuvenate or a similar product and used a steam mop on it. oh well...I'll have to think about this..

Thanks again :-)
