Step 1

Sweep the area with a broom or vacuum cleaner to remove loose dirt and debris.

Step 2

Pour 3 1/2 cups warm water into a clean, empty spray bottle. Add 1/4 cup baking soda and 2 tablespoons each of white vinegar and ammonia. Put the lid on and shake up the bottle well.


Step 3

Spray the stained grout generously with the cleaning solution. Let it sit for a few minutes before scrubbing the grout with a rag.

Step 4

Make a baking soda and peroxide paste into a bowl if the brown stains are still there. Use three parts baking soda to one part peroxide. Scrub the paste onto the grout with an old toothbrush. Let it sit for 10 minutes, then scrub again until the stains are gone. Rinse well with a rag and clean water.


Work in a well-ventilated area when cleaning with ammonia, and wear rubber gloves. Never mix cleaning agents, especially bleach and ammonia or bleach and vinegar. The toxic fumes can be harmful.
