When glue gets on synthetic materials such as polyester fiber, the results can be disastrous if you do not treat the area quickly and efficiently. Polyester is generally more durable and easier to clean than cotton, but it reacts badly to heat, causing wrinkles and loss of shape. This makes it more difficult to remove glue from polyester fabrics. Learning how to remove glue off polyester fiber can mean the difference between saving or throwing away a favorite garment.
Boil some water in a kettle, or in a pan on your stove. Pour a little of the boiling water onto the area of the polyester fiber that is covered in glue. Rub the glue off with a cloth or sponge once it liquefies, if possible.
Place the polyester fiber in the freezer. Wait ten minutes for the glue on the fiber to freeze. Remove the polyester from the freezer and scrape the frozen glue away with a blunt object such as a butter knife or credit card.
Apply nail polish remover to a wad of cotton wool. Dab the wad on the glue to dampen it and let the acetone in the nail polish remover break down the bonds in the glue. Wipe the wad across the glue to remove it. When the glue begins to stick to the cotton wool, discard it and use a clean wad of cotton.
