If the sun has faded your once bright, vibrant carpet you can revitalize it easily. Fill a spray bottle with 1 quart of warm water and 4 tablespoons of table salt. Mix to dissolve the salt. Spritz this over your carpeting lightly. Let this sit for half an hour, then vacuum. The carpet’s color should be reactivated because salt is used in the rug-dying process, so when more is added, the color becomes more vibrant. An extra perk is that the chlorine in the salt seals the color into the fibers so it will be less likely to fade in the future.
