There are mold stains on the ceiling of my bathroom, spots about 1 cm in diameter each). I would like to know which non-toxic product I can use to remove them. There is no fan in the bathroom and no window. There is a skylight that is not waterproof and it is very humid in summer. Will a dehumidifier help?
