Sky remote for sky+ box. Open battery compartment, take out batteries. Find small screw and take out. Now with blunt object, carefully prize open remote. Take out rubber buttons and circuit board. Now for the next bit, i used "MONITOR CLEANER" as it evaporates. Spray cleaner over circuit board, and wipe gently with soft cloth, put to one side to completley dry. Do the same with buttons. Carefully reassemble, job done.
