S,
I have Zaino'd my black, (speckled with "glitter"?) trim
very lightly about once a yearish. Then, when I'm
honking on the interior or even doing a light lint/debris
pickup, I use a microfiber or old cotton t shirt dampend
with water. Sometimes I use a little Windex on the T shirt,
which will be flamed by the purists, but it works for me.
I sometimes use a lightly dampened T shirt with some
Zaino Z6 which supposedly has some anti-stat in it...
I find our black leather interior, black (speckled?) trim,
etc. to be a dust magnet, but what can you do.

Edit: hurtling into my 6th decade year, I failed to realize
that Sudesh may be referring to the
outside trim...
Those sections get Zaino'd a few times per year,too.
Then, just washed normally, and a spritz of Z6 when I
towel dry. No, or few streaks, after 5 1/2 years.
