4. Sunshine!
I personally haven’t put this one to the test, but so many of you recommended this as the best natural way to brighten your whites. Which made me start contemplating a clothes line in our backyard.
5. Borax + Baking Soda
I just discovered Borax recently and it’s actually a pretty great, all natural option. If you have hard water, this is also a great option as softens hard water, removes residue and boosts your detergent. Add a bit of baking soda to really make those whites bright.
