To remove wallpaper, here are common effective steps:

1. Clear the room and protect floors with drop cloths.
2. Find a loose edge or corner and try to peel the wallpaper off the wall by hand.
3. If it doesn’t peel easily, use a wallpaper steamer or spray hot water or a mixture such as water with fabric softener, vinegar, or dish soap onto the wallpaper. Let it sit for 10-20 minutes to loosen the adhesive.
4. Use a putty knife or scraper to gently lift and remove the wallpaper.
5. After removing the wallpaper, clean off the leftover adhesive with warm water and dish soap.

Methods include manual peeling, steaming, chemical or DIY stripper solutions, and scoring to allow liquid to penetrate the wallpaper backing. Steaming is often the most effective and faster method. Patience and care are important to avoid damaging the wall beneath.
