If you have ever had any trouble with grout cleaning, there is a good way to clean it so that it looks new again. The first step is to make sure that the floor is clean so that you have access to the grout. Then, pour some white vinegar onto the grout and allow it to soak into it.
Next, mix up a mixture of baking soda and water and add a touch of dish detergent to the mixture. Then, pour the mixture onto the grout. Next, take a brush with stiff bristles and use it to scrub the mixture into the grout. The grit from the baking soda will allow you to scrub the grout with friction, and the dish detergent in it will clean away dirt and oils.
Continue to scrub the grout until it begins to look new. Once you are finished with one area of the grout, use a sponge to get rid of the cleaning agents that were used on it as well as the dirt that was lifted. Rinse out the sponge often so that you are not simply moving the dirt and grime around. This will give your grout that like-new look.
