Replacement steering wheel control buttons.

[Swotty]

Hi,

2003 CL600TT

I've been trying for several months to clean the buttons at the side of the steering wheel - the ones for the audio controls, 'phone etc. Have tried the recommendations on here .... baby wipes, WD40, nail cleaner, but they're still "sticky", if you see what I mean.

Is it possible to get replacements and are they easy to change, does anyone know, please?

Or ......... anyone know of a miracle cleaner?

Thanks,

Stuart
