How do I clean mold off my bathroom ceiling?
White distilled vinegar works great. Just put it in a spray bottle and spray on to the moldy surface. Wait an hour and then wipe down surface with water. I used to use bleach but it only really works on non porous surfaces. 

Does your bathroom vent well? Try to determine the cause of the mold and fix it. Also, don't let it build up until the next inspections. good luck.
