I had a look in the archive and I don't think anyone has asked this before.

Are the windscreen washer jets adjustable in any way ?

Mine always seem too far apart and so leave a section at the middle of the windscreen at the bottom that never seems to get any fluid on it. As a result it looks very smeery there and is difficult to keep clean. I would like to point the jets a little more towards the centre of the screen if possible.

Im sure if you stick a needle in the nozzle you will be able to manipulate it without causing damage.

Thats the thing, they are not that style where you can just put a pin in them. Its a wide slot in quite a large rigid block of plastic and it isn't obvious if it can be adjusted at all.
