Once the old wallpaper’s off, there might be some lingering patches of paste and sticky residue on your walls. But that’s easy to remove with a quick cleaning concoction of kitchen cupboard supplies.
Step 1. Create a cleaning solution using hot water, washing up liquid and one tablespoon of baking soda.
Step 2. Soak a sponge in this cleaning solution, squeeze it out and wash your walls.
Step 3. This cleaning solution should have softened the residue enough that you can now wipe it away with a dry cloth.
Once your wall is paste-free, leave it to dry for at least 24 hours before applying your new wallpaper.
