How do you remove the brown stains in between tiles in a shower

If you've tried all the home remedies and the commercial ones, the mold has stained the grout. Paint the grout. These poly blends, available on line or at the big box stores works well. Follow the directions and ventilate the room. Good luck.

You need to clean the grout. Try a paste of vinegar and baking soda. Once you get it sparkling clean, I would have it sealed for easier maintenance in the future.

Hello Robert, With a large spray bottle, mix 1/4 cup distilled vinegar, 1/4 cup of dawn dish soap and some say green or blue, but I've used both. With warm water. Shake well and spray the shower and walls, set for 2mins and rise. Spray after each shower it helps keeps it clean.
