I hate removing tag glue. In fact, sad to say, you can see many an item in my house where a tag was only half heartedly removed. Well those days are gone because peanut butter did in fact remove that sticky gunk that a price tag often leaves behind. I stared by removing as much of the tag as possible.
Then, I used a pea size amount of peanut butter and pretty much massaged it into the left over glue with my finger.
Once it was really worked in, I used a paper towel to remove the glue and and the peanut butter.
It looked as good as new. Give the spot a quick wash with soap and water and there you have it!
