I am one that if I find something I love, I love to share with as many people as I can. We are painting a couple rooms in our house, including one that has a wallpaper border around the top. I know to remove the border you need this handy tool:
But, while at the store I looked for the adhesive remover to hopefully make it easier. I picked up this product:
And I am here to tell you this product is a miracle (very similar to Mr Clean's Magic Eraser, in the sense that I am not sure how it works but it does). You spray it on after scoring and within 15 mins the border just peeled like a sticker. I was done removing the border within an hour. So if you still have wallpaper or borders you need to remove, the scorer and this product below is a must have.
