Vinegar has many uses similar to baking soda when it comes to carpet care and one of the most interesting uses is to fluff up high-traffic areas where the carpet looks worn out and the fibers have been flattened. You can dilute vinegar in equal amounts of water and spray on the affected area. Once the material has absorbed the mixture, take a regular spoon and run it sideways along the carpet to loosen the fibers and restore their original texture.
