The dryer is a good idea but try all you can to stop, or at least delay, the problem in the first place. Tube extensions are the go in this department and never leave your scope pointing up if you are not using it, set it horizontal during rest periods.
Another really good preventative for newtonians is to fit a fan that blows the air out the front of the scope. Since fitting one on my scope I have had a LOT less dew problems.
