Fill the tub with hot water.
Pour in the borax, baking soda, and laundry detergent in the proportions indicated.
Stir until the detergent is dissolved, then add your clothes, sheets, and anything else you want to clean.
Soak your clothes for at least 4 hours.
Stir every hour.
After this time, you will see cloudy brown water in the tub.
It is probably dirtier than you expected.
Put your clothes in the washing machine and run the rinse cycle.
Done.
Now your laundry is completely clean.
Other laundry tips: Aspirin is sometimes better than bleach
Over time, white clothes lose their whiteness and begin to yellow, as do the remains of old stains that you have not been able to remove from white clothes for a long time.
Aspirin will help you with this task – during the wash you need to crush a few tablets and add them to the powder – that’s all.
For best results, soak the laundry for 8-10 hours in water in which you have also dissolved a few aspirin tablets (1 tablet per liter).
