    See How to clean a remote control and How to Fix & Clean Your Remote Control Buttons for hints on how to do it.

    Again, just cleaning is suggested and the "black grease" is gunge which should be removed.

    The frequently used keys became flaky again so I attached aluminium foil to them - it's back to like new again.

    There are various conductive paints available I've seen used on the rubber key pads - Amazon, RS components etc sell them.

    Hiya mate,
    which of the two mentioned 'paint' is the best, in your opinion ?

    One important point.

    When you replace the OK key make sure the OK is the right way up. The OK key has two small black tabs, a wide one on the bottom and a thin one on the top. These fit into recesses on the "four arrows" keys.

    I have glued a small dimple onto my OK key so I can easily find it. It means I can't see the OK and I managed to put the key back upside down.

    Everything worked all right until I clipped the plastic front in place when suddenly the Back_arrow key did not send the correct signal. It took a few disassemble / reassemble to work out what was happening.

    Similarly the "four arrows - up/down/left/right" key has a wide tab at the bottom (down arrow) and a narrow tab at the top (up arrow).
