Polyvinyl acetate (or PVA glue) is a common adhesive used for simple projects and in schools because it is non-toxic and washable. If you accidentally drip some PVA glue onto your clothes while you're working—and you don't notice it until it dries—there's still a good chance you can remove it from your clothing. A PVA glue stain should come out by using natural (and inexpensive) methods, without the need for chemicals.
Remove as much dried glue as possible from your clothing by picking off the excess with your fingers—or with the edge of a spoon or similar object.
Submerge the area of clothing with the remaining glue into cold water. The colder the water, the better. Rub some ice on the glue—the cold temperature will break down the polymer bonds of the glue.
Leave the glue in the ice water for 10 minutes. Then scrape some more of the glue off with a plastic bristle scrub brush. Scrub gently in one direction, making sure not to ruin the fabric of your clothing or grind the glue further into the fibres.
Hang the clothing to dry. If all of the glue didn't come out completely, repeat steps one through three. When all of the glue is gone, wash your clothing like you normally would.
If you catch the spill before it dries, just wet a clean wash cloth with cool water and wipe it off of your clothing.
Do not wash your clothing in warm water with any glue still on your clothing, as this will cause the glue to bond further with the fabric.
