Ok ladies - I have never done this but I was curious about this post and googled the topic. I found this "e how to" tutorial - one of the comments was if it did not spray add a few more drops of dish soap.

Another note - if the Elmers is not brand new - it gets thick and gooey. Off topic - I have, at times, used straight Elmers instead of Eileen's when I was out and to quicken the drying I have use a pressing cloth and an warm Iron.
