If you have never used peroxide like this it must be plain white paper towels since colors can run. Also when removing
the poltice you must soak the paper towels in water before disposing of them because if they come incontact with other
chemicals the can catch fire. It's hard to see the fungus in the picture it also may be the towels we wet enough and the moisture reacted with natural iron in the stone that would cause a yellow or brown discoloration.
