Just in time for the 4th! BLOT, don’t rub! Mustard contains tumeric, which is a dye, and if you don’t act quickly, you’ll have a permanent blotch on your shirt. (Hmmmm, why not just wear a yellow shirt on hot dog days?). After blotting, pre-treat with your usual laundry aid, and wash as soon as possible. C’est tres deficile, non?
