Scratches!!
I can't recommend this for any tile or glass - as the other reviewer mentioned it scratches them both!! I have some brand new tile, some of which is a glossy marble look while the other is clear glass tile with a colored back...and I tested using my HAND with both the brown and red pads (the softest) and they BOTH scratched the tile AND the glass! SO glad I tested before putting it on the drill! I have a little haze from the install I wanted to scrub off...but not with this!!
