My cousin spilled this on her clothes when we were working on some crafts and this is what we did..and it worked..
Take a piece of clean cotton and place the pocket face down on it. Press a hot iron on the pocket, pressing for a bit longer than you did to adhere the applique. Peel it away from the cotton. Move the cotton over to a clean spot. Repeat until the glue has been absorbed into the cotton. (You can do this with wax too). Hope this helps you.
