This stain appears to look more like an etch mark from the
picture, if this is true you can try polishing it out with 5X or MB powders, but
will probably need a light honing to remove the etch and then repolish.

See picture. Do you think this
stain will come out with MB-11?
Customer says maid placed a wet
sponge on the area and it feels a little rough.
Thanks for the help.
