How do I get rid of black mold buildup on the bathroom ceiling? I have washed the ceiling several ways and the mold keeps returning.

Steve says : Scrub the walls thoroughly with a strong solution of trisodium phosphate and water. Then swab the affected areas with chlorine bleach and let it sit for an hour or two. Rinse with water then prime with stain killing primer and paint with a mildew resistant latex top coat. The presence of mildew suggests that you have a ventilation problem and you need to install a ventilation fan ducted to the outside to remove the humid air in the bathroom caused by showering.
