Our bathroom does not have a window. It only has an exhaust fan. I have noticed since last few days around 6-8 brown spot on the ceiling of the bathroom. I am suspecting them to be mildew. Please let me know if my suspicion is true and how should I got about getting rid of it. Sorry if the question sounds stupid, but I am a first home owner.
