Hi nafeez,
Welcome to Mrs. Clean’s Forum!
There are several ways to remove bleach stains from tile. Try these simple tips and see which one works for your stain.
Hydrogen peroxide is a time tested favorite for removing stains. I use it for oxidized bleach stains on clothing, and it may work well for this application. Try making a poultice by mixing hydrogen peroxide with cream of tartar or baking soda. Spread the paste on the stains, cover with plastic wrap, and weight it down with a damp towel. This will help to hold the moisture in, while drawing the bleach stains out. Leave on for up to 24 hours, rinse thoroughly, and wipe off with a soft, dry cloth. If the stain remains, you can try another application of the poultice.
You can also try the Magic Eraser from Mr. Clean. They really do work like magic on many stains.
Good Luck and let me know how it turns out!
