We have a tip for your white carpet cleaning. For the best result clean a white carpet water-soluble stains with white vinegar. You need to prepare a mix of 1/4 teaspoon of white vinegar with 32 ounces of water. You can use any other kind of non-bleach detergent in place of white vinegar as well. Then start the cleaning process through pouring the mixture into a spray bottle and spray them right onto the dried stain. Then scrub the area with a sponge for a while and blot it dry with the help of a paper towel.
