Mix a mild dish soap that doesn't have any bleach in it with a cup of water. Blot at the rubber contact glue with a rag. The detergent is going to loosen the bond the glue has formed with the object it is stuck to.
Spray the glue with a spray bottle filled with water.
Repeat the process with the neutral detergent to remove any rubber contact glue that hasn't washed off.
Dry off the area with a clean rag. The rubber contact glue should now all be gone.
