Typically, when it comes to bleaching worn-out socks or collars, chlorine-containing substances or other industrial preparations are used.
In advanced cases, the laundry is boiled, and only housewives who are wise with life experience take on tricks that have been worn out by time.
Here's how to bring back the dazzling shine to your whites.
An excellent option when you need to tidy up small worn-out items, such as socks, scarves or T-shirts. This option also removes stubborn stains and serves as a means of preventing fungal diseases.
So, dissolve boric acid in warm water (20 g per 10 liters of water), soak dirty things in the solution for a couple of hours, and then put them in the washing machine or clean them by hand.
Removes not only stains, but also saves white things that have turned yellow over time. You will need 200 grams of a suitable washing powder, 10 liters of water and several crystals of permanganate. Mix the powder in hot water until completely dissolved, and dilute the potassium permanganate separately to obtain a light pink solution.
Then pour it into water with powder, put the laundry in there and cover with a lid, and when the water cools down, wash it in the machine.
However, these methods should not be used every time. It is advisable to maintain an interval of 1 time in 3-4 washes, otherwise the fabric will quickly become unusable.
