You will proberly say No not that again but mine has clogged up again. I use Skoda screen wash and even opened up the hole on wiper where water comes out and still the b** thing blocks up. What else can I do?.

If you pop the cover off (fingers underneath an gentley pull apart) you'll find the nozzle underneath. It quite literally pops off. I gave mine a quick blast inside with the hose, I also back-flushed it too. Sticking a pin in really only shifts the muck around, a quick jet wash gets rid completely ;)

Mine used to pop off and fill the boot up with water!

mines doing the same, it has not popped off, yet.

only problem is i struggle to reach it! im 5"5 and struggle to reach over the spoiler! :(

Not surprised. When I took mine off I thought I'd see just how much pressure it generates.

Enough to shoot the water about 10 feet above the car!!!

The Skoda rear is worst I have ever had, the design of coming up through the wiper arm instead of direct onto screen I feel is the problem, My front jets do not block up so why do the rears?.

Given that the fronts are smaller holes to create the 'fan' effect, I wonder this too. But not too deeply ;-)
