How Can I Clean White Tile Grout On Floors?
I have white tiles with white grout on the floors of my kitchen, utility room, front foyer and 2 bathrooms. The grout was not sealed when the floors were put in about 12 years ago. The grout is rough and porous which collects dust and dirt, especially in the utility room and by the doors. I want the grout to be as clean as the tile. I have tried magic erasers, toothbrushes and elbow grease, white vinegar, commercial abrasive cleaner, bathtub spray, a steamer. So far nothing seems to help the Disney color of the grout. All ideas welcome.
