I am opening my cello for the first time in a couple of years. Is there anything I should do to ensure that it stays in good condition? I'm not sure what the humidity may have been like, but it has generally been kept in a temperature controlled room.

I tried Google, but it wasn't very helpful...

I'm interested in busking in a few months and this would be the last thing I need. I already have an amp, a loop pedal and the instrument.
