How do you Remove water stain from a lamp shade?

If your lamp shade is a fabric, all you have to do is to wash it in bathtub. If you don't have a bathtub, you can use your large sink. Just put an enough cool water from it, add a mild soap on it and put the lamp shade on your tub and roll it. After a few minutes, drain the water on your tub and refill it with clean water and wash your shade again.

If you're that with it, just use your blow dryer to make your shade dry. I hope this is useful for everyone.
