If present wipe it all off gently. That stuff blocks the keys from making a circuit and the firs sign it's there is having to press keys hard to make them work. Don't know if it's from the rubber or accumulated skin oil that leaks through. Don't rub the conductive coating off the back of the rubber mat.
