Reply to BCD 3000 doesn't work after alcohol spilled on it.

Hello,

Couple of days ago I had a party, where some alcohol drinks were spilled on my BCD 3000. Unfortunatelly, I left it on for a couple of days and now it has allmost died.
I know, that was stupid idea to leave it on, but, well, s*it happens.
Anyway, now when I connect it to my laptop, it finds the device, some faders work, some of them - doesn't. When I try to turn my jogwheel (left one), it seems, that simultaneously many other controls are being pressed.
I disassembled it and wiped everything out, but this didn't help.
What it might be - is there possibility that I cleaned not everything, or some of the contacts oxidized and now there is no chance to fix it?

Thank you very much for any advises provided!
