How Do You Soften Stiff Fabric?
To soften stiff fabric, you can wash it in a mixture of fabric softener and warm water, then tumble dry it on a low heat setting. Alternatively, you can soak the fabric in warm water with a cup of white vinegar for about an hour before washing it in a regular cycle. Adding a quarter cup of baking soda to the wash cycle can also help to further soften the fabric. Additionally, ironing the fabric while it’s still slightly damp can also help to loosen it up.
