What is the best product to buy to clean your socks?

Separate socks by style and color, as washing dark or colored socks and a load of whites may spoil them by bleeding the stains. Add mild detergent to the washer and ensure to wash your socks in cold water on a gentle cycle setting. Soaking white socks in a mixture of water and baking soda can remove stubborn stains and odors. Using a whitening detergent specifically designed for white clothing can help maintain the brightness of white socks. Hanging white socks in direct sunlight can naturally bleach and brighten them. Your best bet is to give your socks a soak in a warm sink filled with a liberal sprinkling of baking soda for several hours. Then, after wringing them dry, wash them in your machine by adding 150-200 ml of baking soda to the detergent drawer, along with your normal powder or liquid.
