Mold on the Bathroom Ceiling

Fill your bathtub with steaming hot water and add to the hot water a handful or two of loose olives leaves. Buy loose olive leaves by the pound. (herbalcom.com is one source and very reasonably price.) Keep the bathroom door shut for about an hour to keep steam inside. Wait and watch the mold breakdown. Then wipe down with a saturated sponge of the olive leaf water solution, and your problem will disappear! Repeat if the problem recurs, which won't happen often, if at all.

After Foxrun41's remedy, always use a mold preventive prior to painting in an area subject to moisture, ie: Kilz..

Make a mixture of bleach and water and apply to the ceiling. In short order the mold will disappear. Rinse with water. Use eye protection. You didn't say what the wrong paint was, that was applied.
