Your doormats and carpets receive the brunt of the dirt and grime as we track it in every time we leave the house. To lift even the most stubborn stains, sprinkle with baking soda or table salt all over the sots. Top off with a little bit of club soda and wait a few minutes before wiping off with a damp sponge. The carbon dioxide in the club soda breaks down the dirt molecules without damaging the fabrics while the baking soda or salt absorbs grime and odors. Welcome home!
