    Hi, My old Panasonic clock radio was playing up (scratchy volume pot) So I have cleaned the pot and some of the other switches with Servisol Aero Klene 50 and now the radio is much better, but there is still some scratchyiness and poor connectivity when I press the Alarm button. Is it OK to spray these type of switches without harming them? ( button switches SW1 SW2 and SW5 in photo). Please excuse the poor photos (taken with Amazon Fire tablet).
    Cheers.

    Yes it is OK, But not always a Cure All.

    Thanks, so can I simply spray around the button and hopefully some cleaner will work its way inside?
    Cheers.

    Some are Sealed really good, But you can Try.

    If NOT, Replace them.

    I have sprayed the button switches and the clock radio now works perfect.
    Many thanks for your advice. IMG_20181104_171842_burst_01.jpg
