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.
