I have these grayish patches on the bathroom ceiling that have been around for a while, i painted over them before but they seem to have come through again. They're about 2 feet apart if that helps. It's directly above the bath tub.
What is it? Is it mould? If so, how do i get rid of it? Painting over them didn't seem to help much.
