One solution that forum users keep mentioning is to open up the box and spray DeOxit into the switch, then work it in a bit. I don't know how long lasting or effective this is and would like to hear from anyone who's tried this.

Its long lasting and effective. My buttons started getting stiff over a year and a half ago, and my sliders started to act funny (jumpy, inconsistent, they developed a mind of their own lol) after the MP had been sitting for about 4 months. Deoxit fixed both of those issues and I haven't had a problem since.The trick with the tact switches is that you have to use deoxit as soon as you notice the buttons are getting stiff. If you keep going, eventually the tact switches will wear out and at that point deoxit is no good.

Seems like this Deoxit stuff is quite magical, so worth a try for non soldering forum users, or even soldering forum users for that matter.
I've tried Servisol but its just not the same.

Anyone giving their tact switches a fix with either method in the near future, let us know how you get on.
Cheers All.
