White clothing can be stylish, yet difficult to keep clean and stains are a common annoyance that can shorten the useful life of your clothing. It is especially important to treat stains as soon as you notice them because older stains can be more difficult to get rid of. If you can treat stains quickly, your clothes can be clean and bright.
Fill a basin or sink with 2 cups cold water and 4 tbsp white vinegar. Add the stained clothing and soak for two hours. Rub the stained areas with a plastic scrub brush for 1 to 2 minutes, or until the stains begin to fade. Scrubbing vinegar into the stains helps reduce the yellow appearance while brightening the clothing.
Launder the clothes in cold water and 1 cup washing powder. Before drying the items, see if the yellow stains are removed. If the stains are gone, let the items air-dry.
If the stains remain, soak the stain in a mixture of 2 cups water and 2 cups hydrogen peroxide for two hours. Wash in cold water using 1 cup detergent. If the stains remain, soak the clothing in 1 cup water and 3 cups hydrogen peroxide for one hour. Wash in cold water and air-dry. The hydrogen peroxide can brighten clothing while safely removing the yellow colour of the stains.
