I got the marble surround installed 2 years back and I have noticed in the last few months that the marble has stained. I don’t know how to treat it. I always clean the surround with mild soap and wipe it but it isn’t helping. How can I reduce or even remove these stains. It’s really bothering me a lot.
Here are before and after pictures. In the after pictures I circled the spot where the stain has spread.
