white carpet cleaning is really a tough job. If you want a best outcome clean the 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.
