Question: is baking soda safe for grout?
Answer: The mildly abrasive properties of the baking soda helps lift dirt from the porous grout, while the hydrogen peroxide acts as a gentle, non-toxic bleach. For even more cleaning power, you can also add a dash of dish soap to the mix. A good ratio is ½ cup baking soda, ¼ cup hydrogen peroxide and one teaspoon dish soap.
