Wiper
Blade
Cleaning
Problems

Common
cleaning
problems
with
thewipers
includestreak-

ing
or
sheeting,
waterdrops
after
wiping,
and
blade
chatter
.

Streaking
is
usually
caused
when
wiper
blades
are
coated

with
road
film
or
car
wash
wax
.
Clean
the
blades
using
soapy

water
.
If
cleaning
does
not
cure
the
problem,
the
blades
should
be
replaced
.
BMW
recommends
replacing
the
wiper

blades
twice
a
year,
before
and
after
the
cold
season
.

Wiper
blade
chatter
may
be
caused
by
dirty
or
worn
blades,

or
by
wiper
arms
that
areout
of
alignment
.
Clean
the
blades
and
windshield
as
described
above
.
Adjust
the
wiper
arm
so

that
there
is
even
pressure
along
the
blade,
and
so
that
the

blade
at
rest
is
perpendicular
to
the
windshield
.
If
problems

persist,
theblades
and
wiper
arms
should
be
replaced
.

The
wiper
blades
can
be
renewed
in
one
of
two
ways
:
either

by
replacing
the
complete
blade
or
by
replacing
just
therubber

insert
.

Insert
replacement
is
the
mosteconomicalmethod,
al-

though
overtime
the
wiperblade
itselfwill
become
worn
.
One

ruleof
thumb
wouldbe
to
replace
just
the
inserts
every
second

time
.
