Oh, no! Your guest accidentally spilled a splash of red wine during an animated conversation. Fortunately, if you did the cooking, you definitely have the remedy on hand. Salt will help absorb a red wine stain while it’s wet, so lightly blot the spot with a soft towel, then cover the stain immediately with a layer of salt. Return 15 minutes later to vacuum up the salt. Spot wash any remaining wine with warm water mixed with mild dish detergent.
