how to clean tumbled marble
My shower floor is made up of 4x4 tumbled marble tile, and it was supposedly sealed. It looked great for a while, but then it started grungy where we primarily stand. I used scrub brush and some mild soap to clean it. When it dried, it still looked grungy, and the grout looked splotchy (darker in some areas, lighter in others). Did I do something wrong? From my understanding tumbled marble isn't as fragile as polished. Is there a fix?
