Themaxx: Standard Deoxit gold
Flo84: Mine were all on the left side of the screen, eq knobs, etc. Personally, I’ve never had a product that lasted in a live/production environment that DIDNT need the faders or pots cleaned at least once in its life cycle. I think more manufacturers need to remember this when designing, honestly 🙂 Cooling will force more air over components, yes, but it doesnt necessarily add dust.. If anything, if the airflow is directly across them, then the airflow actually inhibits dust growth.
Maxdrums: I am confident at least that my board was not a firmware update. I should have taken pictures, but there was lots of oxidation on the contacts for the soft buttons, and I could “feel” the dirt and buildup inside the encoders.
