if you you want to get rid of the soft paint , wich went gooey
i found a simple and effective solution
just pull off the button of the device,
put a piece of cotton cloth like an old t-shirt on you knee
and rubb the button fast and with a certain kind of pressure on that cotton
only the frictional heat will make the soft pain become very soft and loose
and it will stick to the cotton
do that on the top first and then the 4 sides
maybe wipe again with a fresh cotton cloth
this removes the ugly sticky stuff fast and completely
without chemicals or painting them
without damaging the black base coat
never use Alcohol or other solvent… it will remove the black
and you will get a white semi opaque button with no number on iz
the button looks like new but more “plastic” cheaper and less matte
but hey…better then sticky and used
8,15 and Page received this treatment …16 i ruined with alcohol… it works but took the base coat also
