THAT is the kind of information we need! If this is quoted from the
manufacturer then I read it as saying it "can accelerate the corrosion "
(which is true of almost ALL household cleaners since most cleaners are
"mildly alkaline"). I wouldn't worry a lot about the Navy tests and the
lack of a Mil-Spec approval (I was an engineer for the Navy for 25+ years
on
the A-6 program and DID these kinds of tests). The sandwich corrosion and
long-term immersion-corrosion tests would be failed by almost ANY common
cleaning solution. The sandwich test involves trapping the cleaner
between
two sheets of bare aluminum and exposure to different saline environments.
Almost EVERYTHING fails at some level including clean, filtered de-ionized
water. I would say NO cleaner should be left on a surface for ten minutes
(or even be allowed to dry there at all). If nothing else it is a BEAR to
get the film off.
For myself, I plan to continue using Lemon Pledge (ducking for cover) on
my
windshield and will use the Simple Green on my fabric surfaces against
really tough soil (like bug splats on leading edges and belly grime) with
a
GOOD rinse afterwards. I'll continue avoiding the aluminum skins,
especially where two or more layers are riveted together, with ALL
cleaners.
By the way, the Lemon Pledge does a GREAT job taking bugs off leading
edges
and works REALLY well on my wood prop.

Exactly! If used correctly simple green is no worse than any other cleaner
if "used correctly." 409 is much worse than Simple Green but has not been
involved in an aviation myth so it must be OK. Pollutants and soaps carried
into seams can be extremely corrosive. A plane stored inside properly
cleaned with Simple Green is much less likely to suffer from corrosion than
a plane stored outside in a seaside, industrial or high pollutant area.
Anybody that washes their plane by flooding it with water is asking for
trouble.

I think you will find most everybody agrees with your Lemon Pledge comments.
