While staying in Florida last winter, a guild member showed an old quilt (1930’s) wherein the white of the quilt was pure white. She explained that the quilt had had many large brown spots. She had soaked the quilt in the bathtub using a product called “Restoration”, changing the water often. Said the water was stinky and ugly. She continued changing water until the quilt was clean. She had sloshed it about by hand. The results looked as though the quilt was brand new. She had purchased Restoration from the internet.
We didn’t see before photos, but the end results were amazing.
