Dissolve a couple of heaped tablespoons of soda in 1 liter of warm water and soak your socks in this solution overnight.
Then wash your socks as usual, but add about ½ cup of the same baking soda to the drum or powder compartment of your washing machine when washing.
To clean your socks, heat one liter of water and add one teaspoon of white vinegar to it.
Leave the socks in this mixture for about 30 minutes.
Then wash them in the washing machine and your socks will be new white.
It is necessary to put socks turned inside out in the drum.
For more efficiency, put a couple of laundry balls. Pour powder into the tray, add bleach.
Set the desired mode and start the washing machine.
Prepare a solution of hot water, soda and a small amount of plain table vinegar.
Put your socks in this solution; leave them for several hours to soak.
Then wash them in warm soapy water.
If the socks are woolen or synthetic, then hot water will lead to significant shrinkage, so such products are washed in conditions up to 40 ° C in a delicate mode, with a low drum speed.
To wash white and light-coloured cotton socks, set the temperature to 60 °C.
