I have a white velvet dress with little brown stains on it from just hanging in the closet. It was folded up for awhile with the hanger on it, and I wonder if the spots could be rust from the hanger. Is there a way to see if the stains will come out without hurting the velvet?
If the stain is rust on the white velvet, you would need a specific rust remover product. Summit Instant Rust Out and Whink Rust Remover are two such products. These can usually be found in Home Depot/Lowes or hardware stores. A word of caution: ALWAYS read the label directions and pretest the products as they should only be used on whites/colorfast colors (check on hidden color area before using — see label for details).
