I would like to know how to get a "cola pop" stain off a sprayed-on textured ceiling, without you using that dreaded word "painting".
Answer:
Cola stains tend to soak deep into plaster board of any kind so your best bet, if its a small stain, is to paint over it with typewriter white-out fluid. Its about the only thing I know of that will blend into whatever shade of white you put it on.
