hi what solution are you using for tiled kitchen floors
You can try using vinegar and ammonia. Add 7 cups of warm water, 1/2 cup of baking soda, 1/3 cup of ammonia and a quarter cup of white vinegar to a large bucket or large bowl. Allow all materials to mix thoroughly and soda powder to dissolve completely. Then, use a spray to clean your tiles. Of course, you can use a grout cleaner to get a better result.
