John,
A good rule of thumb on biannual tire air rotation is to perform the task while you're adjusting your clocks (or would if your locale went for that) between summer time and winter time. You should rotate the air in the opposite direction of your tire rotation scheme for optimal results.
Beginner,
If you live near an air base, you really should head over there and try to score a couple of containers of Jet Wash, and if they'll part with it, a few lengths of Flight Line. When you need them, there are no suitable substitutes. Depending on who you ask, the Navy will have better stuff than the Air Force; and opinions can be held with strong conviction so caution is advised, especially if both sources are represented when the topic is raised. Remember, your tax dollars helped pay for it, so don't let them try to charge you anything!
