Hi, need some suggestions. Here's my situation:

Wall has a border I put up a year ago. Under the border is primer I painted over an older border that is approx 2-4 years old. So, I want to remove both borders and then paint the wall a new color. I've heard about a vinegar and water solution that removes borders easily. Would this work for my situation? Or, anyone have other suggestions to easily remove the borders?

Thanks!
