Hi Lynn,
Welcome to IIS.
I grew up in Vancouver so I know all about dew.
If you're getting dew-free EPs, then I would stick with your current method. Some people blow them with a hair-dryer (on low heat) but I'm too lazy!
I use the same method as you but give the EP a good shake to get any excess moisture off. I also have been known to actually WIPE mine with a lens cloth from time to time. I know the produces apoplexy in purists, but the coatings and glass and pretty hard and unless you're EPs are covered in dust, you are highly unlikely to do any harm.
Keeping them warm in the scope is another option. Electric eyepiece dew-busters are available from Kendrick and Dew-Not, though I would think they'd be a bit fussy unless you were sticking to one EP.
A heated EP case is another, but that necessitates lugging a power source around with you.
In short the 'cap & dry' method is probably the easiest, and I know of no other that will produce better results.
Standing on guard...
