Simply heat up the base plate with a hair dryer to soften the adhesive. Then use dental floss to gently cut through the foam to remove the 3M Command™ strip from the surface. Stretch or peel off the remaining adhesive.
It is okay to use 3M Command™ strips if the glass is not exposed to direct sunlight or not flooded with water. For example: Do not use inside or outside on south or west windows.
You can, but the adhesive should be applied to a clean, smooth, dry surface when the temperature is above 50°F (10°C). If the temperature is below 50°F, you can heat the surface with a hair dryer before application.
