Resurrecting this thread somewhat after 2 years of hibernation...…
My S8 had been SORNed but I had to tax it to use it a couple of times and then realised that it's MOT is now due fairly soon too - the 6-month extension that isn't after all!
Checking it over the passenger side washer jet is pathetic and I don't want to give them any excuses to fail it.
In the end I dunked it for a couple of hours in NEAT descaler as used above and after that its' perfect. 
Note for anyone who's thinking of doing the same, there's a fair bit of disassembly required to get the nozzle free enough to soak it:
1. Remove wiper blades and arms, remove cover panel over wiper motor.
2. Disconnect washer pipe and heated jet connectors under that cover near the motor.
3. Remove scuttle panel fixing bolts - one each end one in the centre - and lift off panel towards the front of the car. Note locating tongues on the body that fit into slots under the panel.
4. Rather than unclip all the wiring and piping to totally free the nozzle I just undid one cable tie to give some slack in the wiring and took the pipe off then pressed the catch and popped it out of the mounting slot. That freed it just enough to dangle it into a small vessel full of descaler, carefully balancing the panel so as not to knock it all over!
A quick test by connecting a spare length of pipe from near the washer motor directly to the descaled jet proved it was good. Reassembled and tested fine, didn't even need to realign the jets. 
When I've got it through the MOT I'll return to the original challenge and try the alternative jets I have.
