Removing Rust from Tile Floors

Try baking soda, it isnt as abrasive as chemical cleansers and works just as well

Did you try Lime and Rust Remover? It comes in a lime green bottle and you can usually get one at the Dollar store.

Try Sno Bol if it is ceramic tile. If it is vinyl tile you will probally never be able to remove the stain. Be careful with the odor of Sno Bol toilet bowl cleaner. Use good ventilation.

Have you tried the Mr Clean Magic Eraser? It has worked wonders for me on things I have not been able to get clean with anything else.
