"Works so much better than bleach!" : "guaranteed" method of cleaning grout to avoid "damage".

Sally Bremner commented, "Baking soda is mixed with warm water to form a paste. Cover the grout and let it dry, you will be surprised when you clean it. I've used it many times and found it works much better than bleach.

Christine Pyne added, "One guaranteed method I've found is to use baking soda and water. Use both ingredients to make a paste, making sure it's not too runny, and apply it to the grout.

"Then let it sit for about 15-20 minutes and it will turn whiter than ever."

This method is also a favorite of clean influencer Lynsey Queen of Clean , but she likes to substitute white vinegar for the water.

She said: "If you have discolored tile grout, mix a thick paste of baking soda and white vinegar.
