Until I hear back from a Plus Six owner ref the question of play at the wiper arm fulcrum pin I will start with a multiple cleans of the screen with a good glass cleaner, just in case a coating had been applied... I have had a look on the net and I am now trying to find a screen cleaner that everyone says is A1.. As you say the judder is infuriating.. swear

I think the idea of removing one armat a time sounds good. It may be possible to tighten the fulcrum pin if it turns out to be a problem with yours - it certainly sounds feasible that it would cause a judder if loose.

With regard to screen cleaning, I used to use Wilkos window cleaner - found it cleaned really well and did not leave any marks or smears. I use it on the blades as well to clean off any road residue. SInce the demise of Wilkos I've got an ASDA WIndow and Glass (with vinegar) equivalent which seems to do the job as well. I just spray on, and then wipe off with blue roll.
