Hello, I've been living in my room for a year, and recently I've been having problems with mold on my walls. It's in two corners of my room, where sunlight doesn't reach. How do I kill it? How would a high-powered bulb work on it? I've been thinking that it might dry it out. Also, are there any other ways that don't require hiring a specialist that will cost me my month's expenses? How about chemical methods? Thanks.
