Removing wallpaper can be a daunting task, especially if you are dealing with a large room that is papered from top to bottom. The task can be made easier, however, by following these 6 steps

Get started.

1. Assess the situation. If the wallpaper has been on the walls for 30 years, it will indeed be more difficult to remove than wallpaper that is only a few years old. For ancient wallpaper, plan to spend some extra time and effort on getting it removed.

2. Head to the nearest home improvement store. There are two basic ways to remove wallpaper efficiently: by using wallpaper remover chemicals or by using a wallpaper steamer (you can also use a combination of both). In either case, you will need to purchase the proper supplies. For either job, it is highly recommended that you also purchase a wallpaper scoring tool, which is a tool that will score small holes in the wallpaper, thereby allowing the chemicals or steam to penetrate under the wallpaper and loosen the glue. You will also want to purchase a scraping tool to help lift off the wallpaper pieces as they become loose -- a putty knife can also work.

3. Once you have purchased your supplies, you can begin the process by scoring the wallpaper. Use the scoring tool by rubbing it in a circular motion all over the wallpaper. You will see the tiny holes begin to appear.

4. If you have opted to use wallpaper removal chemicals such as a wallpaper stripper, then you can apply the stripper to the wall once you have thoroughly scored the wallpaper. Allow the stripper to set on the wall for the recommended amount of time as per the bottle's directions. Keep in mind that wallpaper stripping chemicals are very potent, so be sure to use them in a well-ventilated room with all of the windows open.

5. If you have opted to use a wallpaper steamer, fill the steamer with water and allow it to heat up. You will see steam coming out of the top of the steamer once it is hot enough. Press the steamer nozzle on the wall and let the steam moisten the wallpaper. The hot steam will loosen the glue and the wallpaper should begin to peel off quite easily.

6. With either of these methods, use your scraping tool to help peel the wallpaper off. You will find that some sections will peel away quite nicely, while other sections will need to be scraped a little bit harder. Be careful when using the scraping tool, and if you find that you have nicked the drywall while scraping it, you should apply some spackle to the area after you are finished.  Try dabbing the spackle with a kitchen sponge.

And there you have it, you just removed that old wallpaper.
