Making a paste with OxyClean and water. Apply let sit for 20 mins. Scrub with toothbrush. Rinse well.
Once it's clean, SEAL!
Hi Joy, You can make a thin paste of hydrogen peroxide and baking soda. Apply it to the grout and let it sit for about 10-15 minutes. Scrub with an old toothbrush and rinse clean. If the grout between the tiles has worn down too far, it may be a better idea to first re-grout and then seal. You can also buy grout pens to quickly “recolor” your grout and make them look new again.
