Sticky radio/AC buttons - cleanup possible?

[amitmishra4]

Hi,

I have a Becker 220 unit in my 2001 Boxster I believe. It seems like something sticky, probably soda was spilt by the previous owner on the CD holder/AC controls and although everything works as expected, there is a lot of stickiness in the buttons, especially when the buttons are first pressed. Touching around it, I can feel something sticky present and seems to have a brownish color, probably Coca Cola or something similar dried up. Does anyone know if there is a tutorial to open up the radio unit and take the buttons off and clean it from the inside out? Any help would be much appreciated.

Thanks.
