tile help! what is wrong with my shower floor?!
What are all these dark spots on my shower tile floor? It's a marble tile purchased from Lowes. I've used every cleaning product (even heavy duty stone and marble cleaners) and nothing has worked. No, it was not sealed initially. I tried cleaning it and then sealing it and it did nothing. What should we do? It's a new home and tile has been there for about 5 months now. It looks so bad in person! Eek!
