I have tried all the chemicals but really hot water seems to work the best and elbow grease. I use the green scrubber pads by Scotch and I scrub a section in a circular motion to loosen the glue then I take it off with a big sponge. If using a bucket to rinse, change the water a lot or you are just putting the glue back on the wall. If you are at all worried that you were not able to remove 100 percent of the residual paste, then apply a coat of Gardz to be sure that paste won't screw up your topcoats of paint.

Use your steamer to really wet the glue, then get a joint compound scraper and scrape it off. The hardware store has them. I suggest a 12" wide scraper. Put down a tarp too, of course.

Thanks for your suggestions.. I'll have to give the steamer a try, it maybe less elbow grease that way (which totally workes for me..lol)
