When I was unpacking from our last move (we're military) I found that the packing company had thrown my wedding dress in a box with metal hangers that got wet and have left stains all over my wedding dress. How do I get rust stains out of white polyester fabric?
There is a product, Brand name Whink, Rust Stain Remover. It is located along side other cleaning supplies in Wal-Mart, and I am sure in other stores as well. I know it works great on nylon and as polyester is also a man-made fiber it should work on it as well, test on a seam or in the hemline to be sure.
