S9B Button got stuck

[mikeorbreak]

Hello, i have the following problem:
The middle button got stuck after beeing pushed. So the watch recognises every button press as a long press.
It can temporarly be solved when i mobilize the button (pushing and turning).
I guess over the past 4 years there ist quite a bit dust or dirt in or nearby the button.
Can i maybe use a lubricant for greasing the button? But i think it could be a problem, that the lubricant may harm the waterproof sealing.
Or do you have any other solution?

If you use the search function you should find other discussions about this and how to clean the watch, using just luke warm water.
