To remove bathroom mold from the ceiling, first ensure proper ventilation by using fans and opening windows. Wear protective gear and clean the area with a mold-killing solution. Scrub the mold off the ceiling with a brush or sponge, and rinse with clean water. Apply a mold-resistant primer and paint once the area is completely dry. Address any underlying moisture issues to prevent recurrence.
