What is the stain on the tile and what kind of tiles are they?
I use Magic Eraser and some elbow grease. It works every time. Let me know if that helps.
You can also use baking soda and vinegar. Here is the post I have for home made cleaner.
Good luck! Bushra
Hi Roger - This is the shower cleaner that we use to help keep grout and tiles clean and minimize the mildew - it works on kitchen grout too. Hope this helps! Hugs, Holly
