My windscreen washers are partially blocked
Over a period of time, my windscreen washers have been getting weaker and weaker, and now my driver side washer is just dribbling, although the passenger side washer is working better.
What is the best way to clear the ducts?When in doubt, run in circles, scream and shout

You sure of a blockage? Have you looked at the pump in the washer bottle. Sometimes they have a gauze style filter on them.

I'm pretty sure its a blockage. However, I had put some detergent into the wather and maybe I put too much because there is a lot of bubbly suds coming out of the driver side. I have got it working a bit, and a some black stuff has come out of the nozzle.

Try blowing pressurized air through the hoses. Or use detergent until all black stuff has come out.
I could really use a fish right now

It's a long time ago but this is what I remember
(1) Try clearing the nozzles with a needle. Sometimes in hard water areas you get a build up of chalk
(2) If that doesn't work you have to progressively clear the pipes. This depends on what you can get to. Sometimes there's a non return valve so you have to do it by stages and always blow towards the nozzle and disconnect the downstream end.(3) Disconnect at the nozzle and at the pump and blow through the pipes (airline or lungs)
(3) Remove the reservoir and flush out all the sludge
(4) Clean the filter in the reservoir.
Other problems:
different detergents can react with each other and form a sludge
Detergent and hard water can form a sludge
Algae can grow in the reservoir forming black sludge - bleach will kill it.
Hope this helpsDuncan Rollo

I don't think that I can remove the reservoir without buggering everything up.
At the moment, I suspect that the short length of pipe to the driver side nozzle may still have some sludge blocking it.
BUT, thanks for your analysis because the fault may be in some combination of what you are stating.
The question here is whether bleach will affect the metallic paintwork of my car.When in doubt, run in circles, scream and shout

I will try to clean out as much of the existing water from the reservoir.
How about baking soda (Sodium bicarbonate?) will that clean out the pipes without affecting the metallic paint?When in doubt, run in circles, scream and shout

I have never heard of blocked washer fluid lines. Valve, do fill the reservoir with water?
