How do I remove glue stains from my cardigan?

"Removing Adhesive, Glue, and Sticker Stains

Stickers
Use an ice cube to freeze the stain. Use a spoon to scrape away as much of the
adhesive residue as possible. Repeat with the ice cube and spoon until no more
can be removed.

Blot the stained area with baby or cooking oil until the residue loosens. Use a spoon to
scrape as much of the residue as you can away. Rinse the stained area thoroughly.

Treat the area with a stain remover stick, spray, or gel. Wash according to the clothing
instructions.

Water-based Glues and Adhesives
Use a spoon to remove as much of the excess stain as you can.

Rub petroleum jelly directly into the stain. Gently rub and remove the glue pieces from
the fabric. To remove the petroleum jelly, rub dishwashing liquid into the stained area and rinse
thoroughly in warm water.

Continue repeating and removing the glue until no more remains. Wash in the hottest water
that the clothing can safely tolerate."
