Line-dry whites in direct sunlight

After washing, hang white clothes on a clothesline or drying rack in direct sunlight rather than using a machine dryer. The sun provides natural whitening that builds on your washing efforts.

Why It Works

UV radiation from sunlight photochemically breaks down residual organic compounds and chromophores on fabric surfaces. This natural bleaching effect has been used for centuries and is still one of the most effective ways to maintain bright whites without chemicals.

Tips

• Works best during strong midday sun in spring and summer
• Turn colored-trim items inside out to protect non-white areas from fading
• Line-dried whites also smell fresher than machine-dried ones
• This method is free and extends the life of your dryer
