Getting rid of outdated or unwanted wallpaper can be a difficult task. It becomes even more challenging when the wallpaper is stuck to the wall behind the toilet tank or another hard-to-reach area. Removing old wallpaper from behind a toilet tank requires a bit of finesse and the right tools.

Preparation and Tools Needed

The problem may be on the wall, but the solution may affect your flooring. Prepare the area by placing old towels and plastic painter’s film behind the toilet, under the wall you will be working on. Use painter’s tape to secure the floor coverings to prevent slipping while working on the wall. Cover any nearby wall outlets with painter’s tape to protect them from overspray from the wallpaper remover.

The tools you will need include a plastic putty knife, a wallpaper scoring tool, safety goggles, a screwdriver, vinegar, fabric softener, and a spray bottle.

Removing the Tank

To remove the wallpaper behind the toilet tank, you need to access it. Shut off the water supply to the toilet using the valve below the tank. Remove the top of the tank and flush out the water. Dry the tank using a wet/dry shop vac or old towels.

Unscrew the coupling of the water supply line that leads to the tank and remove the bolts holding the tank to the bowl. Place the tank in an area outside the bathroom where you have enough space to work.

First Steps in Removing Wallpaper

Find a piece of wallpaper that has started to lift from the wall and insert the edge of the putty knife under it. Be careful not to press the putty knife too hard into the wall, as it may cause gouges that will need to be repaired.

Gently lift the piece of wallpaper at a 45-degree angle while pushing the putty knife underneath it. Remove as much of the wallpaper in strips as possible.

Removing Stubborn Wallpaper

Most wallpapers have an outer layer made of vinyl, bamboo, or textile. Underneath is an inner layer that is usually just paper. Removing the outer layer of wallpaper can be challenging. Lightly use the wallpaper scoring tool on the remaining wallpaper to create small perforations on the top layers.

Mix 1/4 cup of fabric softener with 3/4 cup of hot water in a spray bottle and apply it to the area. Alternatively, you can use a solution of 1/3 cup of white vinegar with 2/3 cup of hot water. Allow the mixture to sit on the wall for a few minutes to penetrate the top layer and soak into the paper underneath.

Use the plastic putty knife to scrape off the wet remnants. If you encounter any dry areas, simply spray the solution and move on to other areas while it soaks. Dispose of the removed wallpaper in a trash bag to keep the small space as clean as possible. When working in tight spaces, such as behind a toilet, it is important to keep the work area clean to minimize the risk of accidents.

How to Get Rid of Wall Adhesive

Once you have finished the task of taking down the wallpaper, there is one final step remaining. The adhesive may leave a dirty film on the wall. You can use the same solution to gently scrape off the adhesive. While scraping off the adhesive, make sure to wipe the wall clean to eliminate any leftover residue. Repeat this procedure until all the wallpaper and adhesive have been successfully removed.
