Thought this might be helpful, our young granddaughter spilled red koolaid on the shade at the dining table. We were sure it was ruined, but there is hope and thank goodness there is Oxi Clean. We removed the shade and laid it out on a large table with white or light colored towels under it,sprayed it with the spray type oxiclean and blotted and scrubbed lightly kept repeating this until stain was gone. Then sprayed lightly with clear clean water and blotted with more clean towels just to rinse the oxiclean out a bit. It got the stain out completely but it looked like the starch was gone in the pleats we let it dry completely and sprayed with some spray starch pleated them up completely then wrapped it tight with strong rubber bands and let dry. They look like new can't tell the stain was ever there. They are very expensive to replace not to mention the fabric ours is made with had been discontinued so all would have had to be replaced, so this was a real money saver.
