If you still throw dirty socks into the washing machine drum right away, don't complain that they haven't washed out.
The problem is not in the powder - before washing, this wardrobe item should definitely be pre-treated by soaking.
First, shake out your hosiery thoroughly to remove any dust.
After this, dip the items in a warm soapy solution, and then rub the feet with laundry soap, but that's not all.
In this form, the socks should be packed in a plastic bag and left for 12 hours.
After the specified time, rub the items thoroughly, and now you can use the washing machine.
It is impossible not to mention another effective method. Immerse dirty laundry in warm water, the temperature of which does not exceed 40 degrees – this is important, since in hot water the dirt will only “stick to the fabric” more firmly.
Now add orthoboric acid to the basin – you will need 2-3 g of the preparation per liter of water. This option is only suitable for white items.
