Have a fabric Biplane and use Simple Green. Spray it on WIPE it off.

DO NOT USE SIMPLE GREEN ON AIRPLANES!!!!
That stuff etches aluminum.

Nonsense. Diluted to proper levels it is harmless. On fabric or paint it
has no effect. Used properly it is fine for aircraft use.

The problem is it (and just about any other liquid) will leech into the
joints between panels and there it sits and does its chemical thing. Sure,
it's fine on the surface of the aluminum, but that's not where the damage
occurs.

Go ahead and use it properly, but you've been warned...

If you let it leech into the joints of bare aluminum you are not using it
properly. On a properly painted surface there should be no chance of it
leeching into bare aluminum.

It's not a matter of letting it - it will do it. Inspection panels may be
properly painted, but it will get between the surfaces.

No,

couldn't agree more. The idea of washing an aircraft and being able to
keep fluid from creeping into seams and slits is preposterous.

I have been hearing the comments about Simple Green for years and that it
will etch or corrode Aluminum. I'm not saying they are true or not but I
have NEVER had anyone give definitive proof that it actually happens.
Everybody "read a report" or "has a friend who knows somebody". Who out
there has actually USED it on aluminum and seen (with their own eyes) the
damage? I DON'T use it on my Taylorcraft cowl (aluminum) because I DON'T
KNOW if it will cause damage, but I have used it on a Concur Porsche, the
fabric parts of the Taylorcraft (over steel tube), numerous steel parts and
LOTS of bare and painted aluminum that is NOT in my plane. I have NEVER
seen any corrosion or etching any worse than caused by Windex, soap and
water, plain water or general etching of the surfaces from exposure to the
elements (like lawn chairs). Has ANYONE ever seen these effects THEMSELVES
or does anyone have an OFFICIAL report of this etching and corrosion ever
happening?
Like I said, I'm not saying it doesn't happen, and I can't prove it does, I
just know the stuff is GREAT for cleaning all kinds of surfaces, smells good
and is CONSTANTLY maligned by the aviation community WITH NO PROOF. If it's
bad, I'll use it in the house and ban it from my hangar, if it's not bad, I
want proof of that too. Who has it?

Hjarrett,

Well, the guys at Aviation Consumer got this from the manufacturer (I
hope it's ok to quote this):

"Simple Green is a household cleaner that’s mildly alkaline. Its
manufacturer, Sunshine Makers, Inc., says “the aqueous-base and
alkalinity of Simple Green...can accelerate the corrosion process.
Therefore, contact times of...Simple Green...with unprotected or
unpainted aluminum surfaces should be kept as brief as the job will
allow...never for more than 10 minutes. Large cleaning jobs should be
conducted in smaller-area stages to achieve lower contact time.”

Sunshine Makers notes that Simple Green doesn’t have Mil-Spec approval
and Navy tests done in 1993 revealed that Simple Green failed sandwich
corrosion and long-term immersion-corrosion tests on aluminum. "

They conclude it wouldn't be their first choice and they would at least
only use it on painted surfaces and rinse very thoroughly.

The U.S. military has published such a statement. Somebody put a link to it here a
year or two back.

In Tennessee, it's evangelism.

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.

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.
