Retro Clean is a powder created especially to remove age spots and and enhance the colors in your fragile and faded vintage linens. I can see this product coming in really handy for thrift-happy crafter types! Simply soak your items in Retro Clean for up to two days–it works best when exposed to sunlight, yet won’t bleach the fabric. Check out their website to order Retro Clean by the pound and to check out before and after testimonials. Link.
