As summer approaches, many overlook the importance of clean towels, which can harbor bacteria and grime. A study by the University of Arizona reveals that fabric softeners, while making towels feel soft, create a waxy buildup that traps dirt and bacteria, diminishing their absorbency. Instead, using washing soda (sodium carbonate) offers a natural solution. This compound effectively dissolves oils and neutralizes acidity, breaking down the stubborn residues that regular detergents cannot remove. To clean towels effectively, wash them separately from clothing, add about 120 ml of washing soda directly into the drum, and use a hot wash cycle at 60 to 90 degrees Celsius. A second rinse can help eliminate any remaining residues. Additionally, sun drying can enhance freshness. This simple switch not only revitalizes towels but also improves overall laundry efficiency, making them cleaner and more absorbent, which is particularly important during the summer months.
