A surprisingly effective natural stain remover
Sweat stains, minor everyday accidents, or food stains: vinegar can also be used as a natural stain remover. Its action helps to lift stains without excessive rubbing, thus preserving the fibers.
Apply 1 to 2 tablespoons of white vinegar (15 to 30 ml) directly to the affected area, leave for 5 to 10 minutes , then rinse with lukewarm water (30 to 40°C) before machine washing.
For light-colored fabrics, a quick soak in 3 liters of lukewarm water with 250 ml of white vinegar for 30 minutes will also revive brightness without dulling the colors.
Softer clothes without fabric softener
If your laundry feels rough despite using fabric softener, vinegar can make all the difference. Where conventional products sometimes leave residue, it cleans deeply and naturally softens the fibers.
Dilute 150 ml of white vinegar with 300 ml of water and pour the mixture into the fabric softener compartment of your washing machine. Your laundry will come out soft, pleasant to the touch, and free of static electricity—especially beneficial for sweaters and sheets.
Preserve the colors and whiteness

Over time, white clothes can turn gray and colors can lose their vibrancy. Vinegar helps remove the deposits responsible for this dull appearance and helps preserve the visual freshness of laundry.
