Windsheild cleaning

Flame #1: Use Lemon Pledge for your windshield. It's cheaper than old
clumps of Mirror Glaze, works better and the FBO's in the desert that
use it have never had to replace a windscreen due to scratches (even
with students.) It leaves a slight flim on the surface of your
polycarbonate (plexiglass)which suspends abrasive particles. But use
the cheapest plain towels at CostCo. I DO work for them on commission,
so you must send me a dollar every time you clean you windshield this
way. ;-)

I make transparencies for a living, so here go's....

Lemon Pledge.... It appears safe on newer acrylic plastics, but I'm still
not convinced. I do know for a fact
that the older acrylic formulations (and they do change) can be damaged by
use of it. The problem is most
likely the propellant gasses used in the Pledge and not the product itself.
Now since most product is
packaged with isobutane it might be ok. I would hate to recommend a product
without knowing what plastic you
are shooting it on. Each plastic company specs different UV packages and
the monomer mix changes from batch to batch.
SO the cautious approach would be to stay away from it if you haven't
started.

Food for thought.
