I don't have any Wash & Wax handy, but I do have Lemon Pledge.
Do you think it would be OK to use it to clean the plane?

I know several folks who have used Lemon Plege exclusively for years and
not had a problem. Maybe they put in some extra elbow grease. Wash &
Wax can be ordered if you can't find it locally, but I would bet one of
the pilot shops in that area carries it. Could also try auto speed shops.

I've been reading Musketeer Mail religiously, but haven't made it to
BAC
yet.
Is there anything there that I won't get at Musketeer Mail?

BAC has a full archive of all of MusketeerMail, as well as a TON of
other information, including all ADs, service bulletins, and the like.
The discussions tend to be more or less along the same lines as on the
yahoo-based list, but the answers are more technical and are always
archived afterward in such a way that they are easy to find. Plus, as a
type club they have some leverage in finding parts, getting insurance
discounts, and a number of other benefits.
