Re: Small ceiling stain...fix?
Try using a product called Clorox Clean-up and spray it generously on the stain. If you don't want to go buy a specialty cleaning product, you can mix up your own bleach solution. Protect the area under and around the spray area so that you don't get drift that will cause bleaching of furniture or flooring. The bleach should take out most of the stain and you shouldn't have to so anything else. If it doesn't work, then spot treat the area with a pigmented shellac (Zinnser's red label primer - in aerosol form ), then paint the entire ceiling.
