[R129 SL] rear plastic window with bad scum

[rett]

Hi All,
I was wondering if anyone could recommend a method or product to remove the
brown "scum" that has accumulated on the back window.  It is especially bad
on my car as I live on the beach in Southern California but do not have
indoor parking.  If it cannot be removed, is it possible to just have the
windows on the convertible replaced?
Thanks,
Rett
