If you want the washing process to be more effective and the color of your clothes to always remain bright, then you should add regular salt to the powder when washing.
In this case, things will also be fresh and soft.
This method works especially well when washing towels, which become stiffer over time.
It is also worth adding that adding salt to the washing machine helps remove limescale and scale from the drum.
It is advisable to use coarse salt.
It is enough to take 1-2 teaspoons of this product.
In this case, washing should be done at high temperatures.
The point is that this will allow the salt to dissolve faster and penetrate into the fabric fibers.
If you don't want to add salt to the washing machine, you can soak the items in a solution of water and salt before washing. For a liter of water, take 3 spoons of the bulk product.
