I left NAVAIR in 1997 and at that time the only thing I had ever seen was
that it wasn't to be used because it wasn't Mil Spec. I kind of discount
the "immersion test" for it's effects in our situation. Almost ANY cleaner
will tear up bare aluminum if you submerge it and leave it there. There are
strict requirements for what you can use on transparencies, and again LOTS
of chemicals will craze them. Ever seen what AvGas does to Polycarbonate?
I take the warning seriously and like I said, I won't use it where it can
get between layers of aluminum but it sure works good on fabric leading edge
bugs and bellies.

From the Naval Safety Center's website:

Dear Editor:

The cleaning liquid, Simple Green, should not be used to clean
aluminum equipment or parts because it is highly corrosive.

According to an article at avweb, a 3.5 gram aluminum alloy sample was
immersed into a container of Simple Green. After one week, the sample
was 295 milligrams lighter. The article further states that the Air
Force issued a statement not to use Simple Green on Air Force
equipment containing aluminum.

Thought you Navy folks would like to have this information.

We appreciate your information about Simple Green. Lt. David Mims,
head of the Occupational and Environmental Health Division here at the
Safety Center, researched the Simple Green situation. He found that
the Naval Air Warfare Center (NavAir) disapproved of the use of Simple
Green for naval aviation in 1993. They have a documented incident of
crazing of an F-18 canopy following the unauthorized use of Simple
Green. According to an official at NAVAIR, they have tested the
product at least three times since 1989. Simple Green fails sandwich
corrosion and total immersion-corrosion tests for aluminum. That
official also said that NAVAIR recommended that commands remove Simple
Green from their spaces. It's just too easy for someone who's told to
clean something to grab a bottle of Simple Green off the shelf and use
it on an airplane or equipment made of aluminum.-Ed.



Like I said, you've been warned.
