I have discovered a simple but extremely effective way to restore the original whiteness even to clothes that have long since lost their fresh look. Even an old yellowed towel after this procedure looks as if it was just bought from the store.
What is needed?
To prepare the solution, you only need two inexpensive products . I grated half a bar of tar soap on a coarse grater, poured the shavings into a bowl and poured one cup of hot water over them . After about 10–15 minutes , when the soap had softened well, I added three tablespoons of ammonia (sodium hydroxide) and another two liters of hot water .
