Pour a small amount of soda water onto a fresh carpet spill, and blot with a towel. Don’t rub, as you may mat the fibers. If the stain is set, try hydrogen peroxide: Pour some onto a clean, white cloth, then press cloth to carpet. Wait about 15 minutes, blot with a clean cloth. There should be no need to rinse. For tougher stains, try our natural carpet cleaners.
