This seemed the most likely newsgroup for such a question, for which I've
been unable to find an answer on the net.
I have been in my new house for about a year. In the master bathroom, I
splurged and installed beautiful Jurassic limestone everywhere. In the
walk-in shower, the floor tiles are starting to look much darker than the
walls and other areas -- and I noticed a similar thing happening on the
countertop next to the vanity sink. In addition to the discoloration,
those areas appear to have lost their matte luster, but I'm afraid to apply
anymore sealer until I figure out this discoloration problem.
The fact that it's happening both next to the sink and on the shower floor
leads me to believe that the discoloration may be caused by something in a
soap or shampoo I'm using, but that's just a guess. The discoloration
extends about half an inch up the wall in the tile, so if it wasn't a soap
I was using on myself, perhaps the softscrub I was using on the shower
floor did it.
In any event, I'm seeking some idea with regard to what I've done wrong (so
I won't do it anymore) -- and if there is any way to restore those tiles
back to their original color and luster.
I don't understand this! I wasn't warned about using limestone in those
areas -- and in fact, I've seen it used in bathrooms for years (and in
Europe, for centuries!). Any limestone experts out there?
Thanks in advance,
