Well, you aren't going to believe this. At least I couldn't believe it. I left work at 4:00 pm and came home. Noticed that Suz' had suggested Kaboom. I used the magic eraser and that didn't work. I sprayed the Kaboom and scrubbed it with a scrubby pad and that didn't work. I used the magic eraser WITH the Kaboom and that didn't work.
I got mad because I figured I'd have to make a trip to Lowes to get something else. I walked away, and 30 minutes later when I went to the door and looked at the tile....it was CLEAN in the spots I had worked on!!!
I'm guessing that the Kaboom had to sit a while. I don't care....it worked and that's all that matters.
Thank you!!
