Remove old wallpaper from the wall
When the change of scenery is about to happen, it is rather tedious work to remove the old wallpaper from the wall. Does not have to be.
Take a used but still functional spray bottle, z. B. from the window cleaner, and fill it with lukewarm water. Spray old wallpaper, let it work and then peel off without much effort.
Of course you can in stubborn cases add some wallpaper remover, as probat is it, with a tip of the spatula anyway in the hand, scratch the old wallpaper before cruciform.
