White clothes tend to lose their brightness and get dull. However, there’s a smart way to make your white shirts crispy and fresh again using nothing more than natural ingredients, which are lemon, vinegar, 3% hydrogen peroxide, borax, washing soda. Just pick one and add ½ cup of it to your load. After that wash your clothes as usual. For example, if you got a lemon in your fridge now, just cut it in slices, boil a large pot of water and add them there. Transfer your lemon/hot water mixture to a tub and let your clothes soak for a while, until the water’s cool. Then just wash normally and it’s whiter than white!
