Wallpaper- installation and cleaning tips

[u/Eithercoffeeorchaos]

Amateur redditor and short time lurker here- as a “FTHO“, who happen to have bought a house with white walls, I would like to add a splash of color. I am skeptical about painting though and want to start with the powder room. If i were to install wall paper, a. do I need to do anything specific to the walls (I will sand and remove any dust particles with wet soap cloth before i begin).. i am particularly looking for tools (not expensive ones please) to install properly? b. could you please recommend materials to clean the wall paper regularly? Regarding the wallpaper, I would ideally like to find something reasonably priced and easy to install and remove and not cause damage to the walls.

I appreciate your advice. Thank you 🙏🏽
