According to restauranteurs, these ingredients will get nasty red wine stains out of your carpet or upholstery. Remember that it is very important to dab not rub, as rubbing will only spread the stain and possibly damage the material. Be sure to use a generous amount of whichever substance you choose. Plain club soda or a mix of club soda and hydrogen peroxide. Salt or better yet, first dilute the stain with club soda then apply the salt. And the most interesting of all: white wine, then salt. Finally, it's always a good idea to wash or dry clean the fabric after any of these tactics, if possible.
