To whiten your laundry in an ecological and effective way, here are some natural products to use:
Potassium permanganate:
Potassium permanganate is a powerful oxidant available in pharmacies. Here’s how to do it:
In a large container, mix 10 liters of water with a few crystals of potassium permanganate until you get a pink color.
Immerse your laundry, clothes or curtains in this mixture.
Wrap the container with a nylon bag or transparent cling film.
Let it sit for at least 4 to 5 hours, or even overnight.
Don’t worry if the water turns a strange color.
The next day, spin your laundry, put it in your washing machine and run the usual washing program.
If your laundry was already washed, rinse it in cold water and hang it out to dry.
You can repeat this method until you achieve the desired whiteness.
