Target sells a countertop cleaner for granite, and I really like it. I've been struggling to find something that works for my pre-finished hardwood floors. If your hardwood is prefinished, do NOT use oil soap nor wax. The oil soap will leave a film and the wax will build up. I've tried the Bona, and the jury is still out on it.

I recently purchased a Shark steam cleaner, and while some my love theirs, I did not. I was not pleased that it only had one steam port and the head did not swivel. I returned it, went to Amazon.com and bought a Haan. It has seventeen ports and swivels. Plus, the flat head fits under the kick plate of the cabinets. I love the Haan, and I think it is all I will be using on my floors.

Many people opposed to using a steam cleaner on hardwood,, and I would not use it on anything without a sealed finish, but the steam evaporates within 15 seconds max, and faster with the ceiling fans on high.

A steam cleaner should work for tile floors and walls as well. The one I bought coverts to hand held and has additional attachments.

Good Luck!
