I agree with Denny, with one additional point.

Before trying this on your aircraft, you should practice
a few times, or at least once, on some else's airplane.

I just happend to have a very dirty 1964 Piper Aztec
that I'd be happy to let you practice on, as many times
as you'd like, free of charge. :-)

Auto or boat shampoos will do the job just fine... There is no
difference between the finish on your Diamond and that on a Corvette or
a Bayliner - or a multimillion dollar Berger yacht, for that matter...
So go to your local auto store or to West Marine, etc., and look at the
paint care products... As long as no silicone is in the contents
listing you are good to go...
Now, if you want my long time (50+ years) tested system, LUX dish soap
for the wash job and for the shine the auto Meguirs 1-2-3step system
will work like gangbusters...
(it used to be Turtle wax or Blue Coral 50 years ago but the Meguirs
system is an improvment - and you probably won't need to use Meguirs
step #1 for a year old Diamond)

Actually, shopping on line is easy, informative, and you just wait for
it to show up at your door...
