I had a white fabric lamp shade that had a yellowish stain all the way around it. It had gotten too close to my son’s vaporizer and water had condensed on it… I didn’t want to throw it out, so I decided to try and clean it, even though lamp shades are notoriously difficult to clean.
First I tried white vinegar, but that didn’t really affect the stain at all. Then I tried a light solution of dish soap and water, but that didn’t help much either. Finally I tried oxygen bleach (I use Oxyboost by Natural Choices — see oxyboost.com). Bingo! The stain came right out. I simply put a tablespoon or so in a cup of water, rubbed it in gently with a cloth, and then let it dry.
Remember that lamp shades are often delicate and don’t do well when exposed to moisture. Use this method at your own risk and always test in an inconspicuous spot first!
