Forgive  me for saying this, but "certain polishes like Pledge" doesn't
negatively  support pledge, in my book. I will personally not hesitate  
to....
 
Hello Greg
 
Quite frankly, I could not care less what you use on your  plexiglass. It 
is really none of my concern. I urged caution when using  wood furniture 
polish on plexiglass. I suggested testing any product intended  for use only on 
wooden furniture on a scrap piece of plexi before  using it on an installed 
plexiglass windshield. This  is only common sense. Nowhere in my post will 
you find  any wording saying to use it or not to use it, nor will you find  
anything "negatively supporting Pledge", whatever that means. If Pledge  
works for you, great! Please, by all means, continue it's use to your  heart's 
content.
 
However, everyone should be aware that wood furniture polish products,  
like Pledge, contain other ingredients besides the wax in the product that  you 
are after to protect your plexiglass. These other ingredients may or may 
not  react with your plexiglass. The fouling ingredient could be a  binder, a 
propellant, a solvent, anything besides the wax in the  furniture polish you 
are after. Why risk exposing your glass to these other  ingredients when 
it's the wax you are after?
 
It should also be noted that companies who make such  commercial products 
for wooden furniture are subject to change  formulations with the ebb and 
flow of suppliers. Different batches of  the same product may or may not 
include exactly the same  ingredients. I doubt the manufacturers of these products 
are  taking into consideration that folks like you are using their product 
on  anything but wooden furniture for anything but polishing wooden  
furniture. I also think you would be hard pressed to find anyone  manufacturing 
plexiglass who recommends the use of wood furniture polish of  any kind on any 
plexiglass product. If you like using Pledge  on your glass, though, please 
be my guest.  It is, after  all, your windshield and it is you who will 
spend the hours replacing it  should it become frosted. 
 
The purpose of my posting was to offer the group insight into how a  
professional sailplane repair shop performs routine maintenance on  sailplane 
canopies. As such, I hope that someone in our group found this  information 
useful, even if you did not.
