We have had wallpaper on part of a kitchen wall for close to 25 years and would like to remove it but unsure of what to use. Any help out there?

Wallpaper is difficult to remove, you will probably end up having to repair some of the drywall after removal. There are steamers you can use that help loosen the glue of the paper making it easier to peal off. Short of hiring a professional to do the removal, that is what worked best for my parents when they were removing wallpaper from various rooms in their home. I believe you can rent these steamers at a local hardware store or a home depot.
