Hi all! As you can see, the buttons on my complete have turned yellow. I never put it in the sun and kept it clean, never smoked around it and took good care of it. But the buttons turned yellow after a few years of use.
Can you please tell me what can be done to make them white again?
Maybe somewhere I can buy new ones? I couldn't find anything. Or maybe they can be cleaned?
Interestingly, when turned off, they do not look yellow. When the buttons are off, they look quite white.
For comparison, I apply the color of the buttons of my Machine. Here they are white even when turned on.
