artist mix fader&buttons issues

[joesbrands]

hi!

my artist mix (euphonix, 5years old) don't function that well anymore.

- some buttons don't react (unless you keep trying or push really hard
is there a way to clean the contacts?

- some fader freeze unless you take the caps of (then no problems at all)
recognizable for anyone? is there a solution?

thanks!

If I were to guess at the faders, the saddles might need a good cleaning with 99% isopropyl - including the slot where they fit over the fader stem.
