How do I clean painted bathroom walls?

My bathroom walls have a build up of hairspray, soapscum and mold. I have used Pine Sol. That helped for a while. Do you know a cheap, safe method that won't strip the paint, but will leave my walls looking as good as new? And no, I don't want to repaint!|||TSP is the best thing I have found to clean painted walls. If it is cheap paint, you may have to touch up some spots. But, anything that will clean a wall will take off cheap paint. You can buy TSP at Lowe's or Home Depot or any store like that. TSP is very inexpensive.
