Three Rules of Condensation

1)  Moving air changes dew point temperature. Never underestimate the power of moving air to reduce condensation.

2) Condensation is temperature sensitive. Increase the air temperature and you increase the   moisture-carrying ability of air to hold more moisture. 

3)   Reduce moisture. Do this by reducing moisture at the source (usually cheap to do) or mechanically reducing the amount of moisture in the air (usually rather  expensive to do).
