To remove Elmer's white glue from clothing, soak the stained area in warm water or a solution of water, detergent and vinegar to soften the glue, then wash immediately in hot water. Do not use vinegar on cotton or linen.
For the best stain removal results, try to remove the glue before it dries. If the glue is already dried, use a knife with a flat blade to scrape the excess glue off the surface of the fabric before soaking. For washable fabrics, soak the fabric in a solution of 1 quart warm water, 1/2 teaspoon of detergent and 1 tablespoon of white vinegar for about 15 minutes. Rinse the garment well, then wash it in water that is as hot as possible, but not so hot that it will damage the fabric. If the glue is on cotton or linen, omit the vinegar from the solution and instead sponge the stained area with rubbing alcohol after rinsing it. If the glue is still present after the article has dried, soak it in cold water for another 30 minutes, then sponge the area again with a cleaning solvent or alcohol before re-washing.
For non-washable fabrics, keep the glued area damp with a sponge and blot on a few drops of white vinegar. Try to lift the stain with an absorbent pad. If the stain still appears it may be advisable to consult a professional dry cleaner.
