Lemon, the king of white garments
Lemon is a great natural bleach. To restore the brightness of your light clothes, you can cut two lemons into slices and add them to 1 liter of boiling water. After soaking the pieces for 40 minutes, you can wash them by hand or in the washing machine as usual.
As an alternative option, you can apply the juice of two lemons directly on the stains you want to remove. Rub it on the clothes, let them dry in the sun for at least two hours, and then wash them as you usually do. The effects are amazing!
