I tried one of these ideas on the badly stained grout around my toilet. Baking soda, vinegar, baking powder and lemon juice, mixed together into a thick paste. I used an old paintbrush and applied it all around the toilet. I used the brush to squish the stuff in. I let it all sit overnight, and then spent a lot of time wiping it all up. Oh dear, what a mess, and it only helped a tiny bit. I cannot afford to hire a professional grout cleaner, not on what I make cleaning!
Any other ideas I could try out??? It looks disgusting. My only other idea is to buy grout paint and put that on, but that stuff is not cheap. Could I, maybe, use a matte white acrylic paint?????
