Clean Grout With Peroxide & Baking Soda

Cleaning grout is a necessary chore. While there are many cleaners available on the market that boast about being able to clean grout and anything else, the price tag can be a bit much. All you really need is a couple of inexpensive items you probably already have around the house.

Step 1

Dampen the area with a soft, clean, damp towel.

Step 2

Sprinkle baking soda all over the dampened grout. The moisture will help it to stick.

Step 3

Allow the baking soda to sit on the grout for 10 to 15 minutes.

Step 4

Dip an old toothbrush in hydrogen peroxide and scrub the grout with it. The baking soda will act as a mild abrasive and help to help to clean stubborn areas.

Step 5

Rinse the area with clean water to remove any dirt, debris and baking soda.
