How to do it?
Add  about 100 ml of white vinegar  and  a tablespoon of lemon juice  directly to your washing machine’s detergent drawer (or to a basin if you prefer to soak). Not only will your clothes come out lighter, but they’ll also smell  pleasantly fresh .

Little bonus:  this mixture also helps remove laundry residue and  extend the life of your clothes .
