To remove glue dots from a wall, you can try the following steps:  Use a plastic scraper or credit card to gently scrape off as much of the glue dot as possible. Be careful not to damage the wall surface. Apply a small amount of rubbing alcohol or nail polish remover onto a clean cloth. Rub the cloth onto the glue dot in a circular motion, applying gentle pressure. The rubbing alcohol or nail polish remover should start to dissolve the glue. Use a clean cloth to wipe away the glue residue. If the glue is particularly stubborn, you can try using a mixture of warm water and dish soap. Dampen a cloth with the solution and rub onto the glue dot in a circular motion. Rinse with water and dry the area. If all else fails, you can try using a commercial adhesive remover. Follow the instructions on the product carefully, and be sure to test it on a small, inconspicuous area of the wall first to ensure it doesn't damage the surface.
