Tuner condensation

I noticed just lately on my Kenwood 8300 tuner the clear plastic at the edges has a slight moisture buildup. I was wondering how dangerous was this, and should I open up the tuner and possibly treat and clean this up? On some dry days I noticed it to be clear and fine and yes of course on higher humidity days the buildup at the edges only seems to appear. I am living at the moment in a tropical climate in Florida, so yes I would have to say that this is most common to this area. I was just wondering from some of my fellow Audiogoners what their opinions and what they had to do to remedy this problem.Thank you all who do respond.
