It would seem that bringing the once snow-white tulle back to a proper appearance would not be difficult.
However, in practice it turns out that even after washing, there are still stains on the curtains here and there, and their color has nothing in common with dazzling white, but rather resembles a yellowish or dirty gray shade.
If you are faced with a similar problem, take note of a useful life hack that will return your curtains to their lost whiteness.
For this you will need products such as salt and milk.
4-5 tablespoons of salt should be dissolved in a liter of milk.
Once the mixture is ready, spread the tulle on a flat surface and soak it with the resulting solution. This can be done conveniently using a soft brush.
The curtains should be left in this state for 2-3 hours.
After the specified time, wash the tulle in the usual way - by hand or in a washing machine and you can enjoy the result.
