Collect whites
Choose the right detergent
Since blue increases the impression of white, the best solution is to use a powder detergent enriched with optical brighteners, substances that dye the fabric thanks to a blue or purple dye. You can also simply add a whitener to your usual detergent
Good to know: don't forget to separate the whites from the colored ones! If you wash the sheets together with dark clothes, you will see that in the long run they will turn gray!

Grandma's tricks
To reinforce the illusion of white, add pieces of blue chalk to the rinse compartment of the washing machine. Before doing the washing machine, you can also soak the whites in a basin containing hot water and chemical yeast.
Another trick is to add a glass of hydrogen peroxide or 500 grams of baking soda to the rinse water. You can also put two tablespoons of sodium percarbonate or sodium crystals in the washing machine drum, but in this case you have to halve the amount of detergent and use a program that does not exceed 40 °. Start the washing cycle and stop it after half an hour. Soak your clothes for at least 8 hours and then restart the cycle.
The special cases
- Yellowed white items
