White socks stay white until you put them on.
After you take just a few steps in white socks, you can forget about their whiteness.
Unfortunately, the situation does not improve after washing. Under the influence of washing powder, the stains, of course, disappear, but the products acquire a gray tint.
However, there is a solution that will help restore their original whiteness and avoid unnecessary expenses.
To do this, you will need to mix two tablespoons of baking soda and two tablespoons of citric acid in a small bowl (the amount can be varied depending on the number of socks, the main thing is to maintain a 1:1 ratio).
Add a little water, just enough to make a paste, and apply the mixture to your socks.
Then wash them by hand and rinse thoroughly in a basin filled with warm, clean water.
Thanks to citric acid, yellow stains will disappear, and soda will remove grayness and stubborn stains from the fabric.
