halford own make and bosch etc have graphite on. its just a lubricant for the first few times they get used.
my wipers are hopeless. car is about 6 weeks old now and the skip and jump all over. the passenger side one moves around loads when I'm driving too. seems whatever mechanism or linkage they run off has loads of play in it?
I've tried muc-off glass cleaner and rain0x cleaner and replant and it doesn't make any difference really.
also the auto wiper function is a joke. even in the slowest setting they're far to sensitive. if if misty and not really raining they just go mental. can't tell the difference between rain and fog/mist.
and why in manual mode does the intermittent wipe do what it wants and not have a set timer? crap design IMO
Ken, I agree they're a bit on the sensitive side, but my GTd wipers are rock solid with no squeal or judder and a major improvement over my old Bora whose rain sense wipers hardly worked at all, it would pi$$ down and perhaps I'd get one sweep of the screen! But just before I sold it on I had to have another new screen installed and the wipers worked much better!?? Weird.
Personally, if the car is only six weeks old, I'd speak to my dealer if they skip and jump and seem to be loose in any way, it *may* be a safety issue?
<EDIT> BTW, I use Autoglym's glass cleaner, no problems with it.
