The way you wear your sweater also influences how often it should be cleaned. If you’re wearing a layer underneath that prevents direct contact with your skin, you may be able to go longer between washes. In contrast, if you wear your sweater directly against your skin, it will likely require more frequent washing. Sweaters worn for active use or in smoky environments will also need more frequent laundering.

When you do wash your sweaters, consider whether they should be hand washed or if they can go in the machine.
1. Hand Washing: Hand washing is gentler on delicate fibers and is recommended for most wool and fine-knit sweaters. Use cold water and a gentle detergent, and avoid twisting or wringing the garment.
2. Machine Washing: If your sweater is machine washable, use a gentle cycle with cold water and a mild detergent. It’s also a good idea to turn the sweater inside out and put it in a mesh laundry bag to prevent damage.
