SAEDNEWS: Clothes that retain a sweat smell after washing often need more than a regular wash cycle. Proper pretreatment, the right water temperature, enough airflow, and complete drying can help remove odor-causing residues and keep fabrics fresh for longer.
According to SAEDNEWS, heavily sweat-smelling clothes should be treated before putting them in the washing machine. Soaking them in cool or lukewarm water with a small amount of baking soda can help loosen trapped odors. Let the clothes soak for about thirty minutes before washing.
Giving clothes enough space inside the washing machine allows water and detergent to circulate properly. An overloaded drum may prevent sweat residues from being removed completely, leaving an unpleasant smell behind even after the cycle finishes.

The recommended temperature depends on the fabric and the care label. Cotton and other durable fabrics can often be washed with warm water, while delicate materials may require cooler settings. Following the garment's washing instructions helps clean the fabric without causing unnecessary damage.
Using too much detergent does not necessarily make clothes cleaner. Excess detergent can remain in the fabric and sometimes contribute to buildup that traps unpleasant odors. Use the amount recommended for the load size and detergent type, and avoid combining too many cleaning products.
Leaving damp clothes inside the washing machine for a long time can encourage musty smells. Remove them soon after the cycle ends and dry them completely in a well-ventilated place. Making sure the fabric is fully dry before folding and storing is one of the simplest ways to keep clothes smelling fresh.
