Try a window washing solution. either windex, or just vinegar and water... I've used it many times to remove stickers from mirrors, furniture... you name it!

Try Goo Gone.

I betcha that the hair dryer trick for removing lables, shown previously on AT, would work swell.

Goo be Gone works. Pour or dab some on there, let it sit a few minutes, then scrape or rub it off. Add more as needed.

Did you try a magic eraser?

i think i recognize the adheisive.. its kind of a puffy pad that tears apart instead of peeling when you pull on it. I had to deal with some of that stuff of the walls at work.

you might have luck with a razorblade.. if you can get it under one corner.. then hold that corner back and pull as you "cut" the thing off the wall.. dont try to push the whole blade under it, but use the corner edge of the blade to un-adheire (?) the exposed back.. if that makes any sense.

*kinda like if the wall and sticky thing were a loaf of bread, and you wanted a slice of only sticy crap.. or maybe like trimming the fat off a fillet? maybe not.

goo-gone may also work, but it will leave a discolored spot on the wall.

oh- looking at the photo.. if you have junk left on the wall afterwards.. use a damp cloth and kinda scrub in just one direction. that should make the gummy stuff clump up into balls and you can pick them off the wall.. like rubber cement residue.

finally, i can put my 4 years of office building maintenance experience to use!

Goo Gone. I just used it to take some of those sticky tabs off tiled walls. Works so well.

I'll seventeenth the Goo Gone WITH the aid of a putty knife. I bought the super big spray bottle because I couldn't figure out how to drip the stinky stuff down behind the velcro.

But like someone else said, what do you use to get rid of the Goo Gone residue!? Maybe rubbing alcohol?

Had my share of dealing with "weird things stuck to walls" doing faux finishing for a living.

Sometimes just a bit of mineral spirits (turpentine) on a rag will do the trick.

KRUD KUTTER available at most hardware stores. Ingredients read: "A proprietary blend of biodegradable surfactants, detergents and emulsifiersm in a water based solution. No petroleum solvents, blean or ammonia."

Goo Gone sometimes takes off more than you anticipate.

Rubbing alcohol works well, and will be gentle on the paint.

Last time I pulled off a chunk of my dry wall because I wasn't careful. The blow dryer trick could've done wonders I think.. should've read AT first!

99% medical grade alcohol with take it off with ease. Find at a medical supply store. Great around the house for a zillion uses.

Aw, crap. I just bought some cork squares that come with precisely that kind of awful adhesive and obviously I'd like to avoid ending up with this situation. Any suggestions on how I might hang them instead?

goo gone!

Eucalptus oil. Gets sticky tape, glue, stickers and any other kind of sticky goo off almost any surface and smells good too.

WD40

theres this great citrus based product called de-solv-it, it's made by a company called orange-sol, and you can get it at Wal-mart (or at least thats what it says on the web page). I swear by it at work, I spend about two days a month predominantly removing labels.

Just dab it on with a tissue generously and leave it to soak for 5 minutes (make sure you remove as much of the gunk with a craft knife first, but don't be too fussy) the soaking is a very important part of the removal process. After that it should just wipe or peel off. If theres a residue just wash the patch of wall with some warm soapy water.
