How can I clean bath tile that is horribly stained?
I've inherited a home with a bath enclosure that is horribly stained. I'm not sure if it's porcelain or ceramic but it's supposed to be white tile. I have tried Greased Lightening, straight up bleach, Ajax with bleach, 5 in 1 Scrubbing Bubbles with bleach and the yellowing will not budge. I've been able to scrape off the grout to remove the brownish stain and bring it back to white. I believe cigarettes and soap scum built up over years of no proper cleaning have caused the problem. HELP!!!
