Yes, you should wash it before using it. There's a lot of dust involved in its manufacturing process. Otherwise, people with sensitive skin may experience allergic reactions.
How to wash a flannel blanket:
1. Take it to a professional cleaning shop: Dry cleaners are readily available. For large items like flannel blankets, cleaning at home isn't convenient, so many people choose to take them to a professional cleaning shop. This is simple, convenient, and saves time. Professionals can clean flannel blankets with peace of mind, although it's more expensive, it definitely saves a lot of time. If you wash your flannel blanket at home, improper rinsing or incorrect washing methods can damage it.
2. Hand wash at home: If the flannel blanket has been used for a short time and is not stained, simply soak and gently rub it repeatedly until the desired effect is achieved. Never use a brush. Many people don't realize that a brush can be just as damaging as a washing machine, ruining the fabric and shortening the lifespan of the flannel blanket. Adding a few drops of vinegar to the washing water can effectively prevent the blanket from looking old. Because flannel blankets are soft, elastic, full-feeling, and warm, dry cleaning or hand washing is best. Never use a washing machine, as this can easily cause them to lose their shape and reduce their softness and warmth.
