It acts as a natural disinfectant, eliminates bad odors and softens the fibers. You just have to add a cup to the wash cycle (without detergent). You can also do a pre-wash with hot water and vinegar to intensify the effect.
Baking soda
Excellent for neutralizing odors, removing stains and removing detergent residues. Use in conjunction with vinegar or on a separate cycle. Place half a cup in the washing drum and activate with hot water.
Lemon juice
Its natural acidity acts as a mild bleach. Ideal for yellowish spots or gray areas. Squeeze 2 or 3 lemons in hot water, let the towels soak for an hour and then wash them as usual.
Hydrogen peroxide (3% hydrogen peroxide)
Effective at disinfecting and rinsing without damaging the fibers. Add half a cup in the main wash or use it to treat spot spots before washing.
Coarse salt
Helps to fix colors and remove accumulated moisture residues. Mix a cup with hot water for an initial soak, or add it directly to the drum with your usual wash.
 Tips and advice
Avoid using commercial fabric softener: it reduces absorbency and fixes bad odors.
Dry towels in the sun whenever possible to disinfect them naturally.
Wash towels separately from other clothing, especially synthetic clothing.
Don’t overload the washing machine: towels need space to rinse thoroughly.
If they still smell, do a double wash: first with vinegar and then with baking soda
