Laundry day can be daunting, but experts from Which? have clarified how often you should wash your clothes. According to their guidelines, items such as underwear, workout gear, and swimwear need washing after every use, while jeans can last for 6-10 wears before needing a wash. Other clothing items have varying recommendations: T-shirts should be washed after 1-2 wears, dresses after 1-3, and bras after 2-3. It's essential to consider factors like activity level, climate, and fabric type when determining wash frequency. For instance, if you're sweating heavily or in a humid environment, you'll need to wash your clothes more often. To maintain the quality of your garments, use cold water, gentle detergents, and avoid overloading the washing machine. Sorting laundry by color and fabric weight is also advisable to prevent damage. These tips can help keep your clothes fresh while extending their lifespan.
