Moisten a rag with warm water. Hold the rag over the glue spot for five minutes to soften it.
Wipe off the glue from the wall using the wet rag. Rinse the rag with warm water, wring it out and hold it onto the spot for another five minutes if the glue is still there. Repeat this process until all the glue is gone.
Run an iron over a damp cloth if the glue is still not coming off. Use the iron to heat up the rag, then immediately hold it over the glue spot for a few minutes. Wipe the wall with the rag to remove the glue.
