Here is the response back from SC Johnson, manufacturer of pledge furniture
polish, about my questioning if I could use this product on aircraft
Plexiglas:
"
Please know we have not tested this product on the surfaces you've described
so we cannot recommend it. We design, formulate and test every product for
specific household tasks. That's why we always recommend using products
according to their label directions.
"
So..the product was not designed with Plexiglas in mind, they have not
tested it, and therefore cannot recommend it. Their response doesn't really
surprise me, I am sure they don't want to take any responsibility for
anything the product is not specifically designed for, especially with
expensive aircraft canopies (which I had baited them with, in my question).
Thus I took the liberty to analyze some of the ingredients in more detail
(to the best of my limited chemical abilities), and I include it here as an
attachment.
The final analysis is not black and white (there is no FINAL analysis), and
one of the ingredients may not have quite been figured out but I think it is
close, and quite revealing about the usage of Pledge on a canopy.
There will always be some who will scoff at the idea of using Pledge, only
because it is not made specifically for airplane windshields. That is fine,
and it is a nice conservative approach, especially where there is liability
(to customers) involved. Opinions are many and all varieties are expected. I
think a look at the ingredient comparisons to other products could make a
few jaws drop, though. This topic has been an ongoing learning experience
for me, and the difference in opinion is what has driven me to do the
research. It is worth it. There could be some more research in the future,
or additional inputs by real chemists (or anyone else for that matter), with
comments, or additional data.

I sent an email out about 9 hours ago to a SC Johnson Consumer Service
Representative. They should be getting back soon..

Subject: Re: Europa-List: Re: Windshield care and Pledge
Has anyone asked Pledge whether that firm recommends it for our use on
plexiglass in aircraft?
