slimy windscreen fluid

Hose the lot out, fill it up again, add a tiny bit of bleach, kills whatever's growing in there, run a bit of that through, flush out again and put in screenwash. That's what I did to my bother in law's Orion. The pump was fairly easy to get to - perhaps you need to remove an undertray or something.

The only time I've met that was on a Fiat Uno - and I had to take the bottle out and wash it with scalding water to get the gel out. And then blow the pipes through with an air line. It wasn't a nice job 'cos every now and then, no matter where you stood you got slimed with something like the ectoplasm out of Ghostbusters.

I ran it through with Milton solution when I'd finished to sterilise the works and told the owner to stop cutting corners and using washing up liquid.

Same problem on the Citroen. Smelled like sewage when you used the washers. Cured by splashing out (Ha!) on a big container of ready to use solution, after filling it up with hot water and washing up liquid a couple of times. DaveK.

boiling hot water and wash it out the system by pressing button continually until empty.
