Spray a mixture of water and dish detergent onto the wall, and then scrub to remove tile adhesive from drywall. Care must be taken so as to avoid damaging the drywall. This process requires a drop cloth, a dusting cloth, a mop, warm water, soap and a hair dryer. Removal time depends on the size of the area./
Cover the area around the wall with a drop cloth to catch falling debris. Cover any electrical openings to prevent debris from getting into them.
Create a mixture of water and dish detergent. Spray the adhesive with the mixture. Scrub the wall to remove as much of the adhesive as possible. Wipe the wall with a damp cloth.
Strong glue bases such as duct tape require the use of a knife or blade. Insert the knife or blade under the corner of the adhesive, cutting the contact between it and the wall. Be careful when applying pressure with the knife or blade, as this could damage the wall. Wipe off the adhesive as you go. Heat the adhesive with a hair dryer to speed up the process. If the adhesive will not pry away from the wall, rent a wallpaper steamer. Use the steamer to melt the adhesive. Wipe the melted adhesive away with a damp cloth.
