Does baking soda and vinegar clean tile grout?
Does baking soda and vinegar clean tile grout? In a small bowl, make a paste with baking soda and water. Dip your toothbrush or grout brush in the paste and work it into the grout. Spray the area with your vinegar + water solution. The vinegar will cause the baking soda to bubble up and will start to work away that nasty soap scum.
