Conventional cotton production often relies on bleach for the final look. You may even notice your traditional cotton bedding is a crisp, clean white. Organic cotton is bleach-free, as are all organic textiles.
An excellent way to tell if your cotton products are organic is if your item has an off-white coloring. Organic cotton uses safer alternatives to chemical dyes and whiteners. Some products include natural or water-based dyes for whitening.
