Use a commercial wallpaper remover spray

Spray a product like DIF or Zinsser wallpaper remover directly onto scored wallpaper. These enzyme-based or surfactant formulas penetrate and dissolve adhesive faster than homemade solutions. Wait the recommended time (typically 15-20 minutes) and scrape.

Why It Works

Commercial removers contain surfactants and enzymes specifically formulated to break the bond between wallpaper adhesive and the wall surface. They penetrate faster and more evenly than water-based DIY mixes.

Tips

• DIF is the most widely available brand and costs about $8-12 per concentrate bottle (makes several gallons)
• Gel formulas cling to vertical surfaces better than liquid sprays
• Still requires scoring first for best results
• Follow with a warm water wash to remove any remaining adhesive residue
