Found this strange instrument on the street today...it is made to suppress earth radiation ...

Just in case one has to deal with an #OldDevice with a rubber-like surface that gets sticky over the years - isopropyl alcohol and cotton pads did the trick for me. Works at least on a ten year old Logitech mouse and a #Nokia6233 from 2006 (which has survived falling down a six-story staircase in 2008).
PS. When cleaning mobile phones, it might be a good idea to protect the camera cover.
