How can I clean a cultured marble shower floor?
White cultured marble shower floor is stained with what ? I don’t know. The walls are perfectly beautiful. The shower floor has a build up of something? Or any ideas?It looks dirty. I have naturally soft water not hard. I keep the shower clean with recommended cleaners. I’m the original owner of house so I know nothing harmful was put on it. What about those white cleaner sponges? Or?please Help thx
