I think the 30 to 40 volume peroxide will be your better selection.
I would mix up a poultice with the peroxide apply allow to work for at least 24
to 36 hours then inspect the problem. If it is gone great, if it is lighter
then apply another poultice. I would hone with at least a 120 grit diamond to
open the stones pores prior to applying the poultice.

Since I
last wrote in. I went at the stains with a very aggressive diamond and was able
to lessen it. Therefore I believe it is coming from the top and not
coming though the bottom. It has penated to deep to
remove mechanical so I prefer to remove it chemically.
I have also learned that the sewage system has backed up in the past. I
was going to test it with 35% hydrogen peroxide for organic matter. A
friend of mine suggested that I test an area with RSR 2000 from Alpha.
>From what I understand it removes more than just rust stains.

floor
Has anyone
ever seen this before? I tested a area with bleach to see if it was
mildew and it was not. I tried honing an area to see if it was topical it
was not. I asked the owner if she had ever used hair dye or any other
bath supplies that may have that color in it. Reply was no. Their
contractor suggested that it may be from the floor pan. But as you can see it
is on the shower bench in photo #85. Excuse the color different
on the bench photo I used a flash. And it has a different exposure but is
the same color stain as the floor.
