Washer Nozzle Jets Completely Blocked After 4 Years

[Tox Laximus]

Got the car in 2020 and over the last 6 months the spray has got gradually lower and lower.

Checked the pipes and they are ok. took off the plastic jets and blew into them with a bike pump, one was blocked and the other let some air though, dunked them in warm water did not work, tried descaler did not work, tried switch cleaner and managed to clear them quite well or so it seemed.

Put them back on the car and even worse. 

Ordered a new set from Cox Motor Parts, cost is just over 40 quid for both which is slightly cheaper than honda parts uk or ebay, they are not identical, one is drivers side and one is passengers side, they are colour coded, blue dot is for drivers side, they are horrendously over-designed and intricate inside, its no wonder they blocked.

They may also be a problem with the pump but it sounds fine and it runs freely when disconnected to the jets.

Drilled the end that connects to the hose with 2mm drill and 25-30mm deep, good as new.

Bits of plastic and rubber came out, I think these tiny bits and pieces are there to create smooth laminar flow but because they are so intricate they became blocked, you don't need laminar flow on window washers that's crackers.

Have you, perchance, been using washing up liquid in the washer bottle??
If so that is your problem! It contains salt and will completely block washer jets.
You need to flush the tank with hot water and keep doing so until the water shows absolutely no trace of 'gunge' .
If you can get the either end (preferably the tank end) of the pipe. disconnect and run hot water through it. Do it in short bursts, otherwise you run the risk of burning out the pump!

Always use same tesco washer fluid mixed to the correct ratio, there was no residue on the jets or in the pipes at all, they were very clean, when drilling them out a tiny rubber washer came out along with white plastic stuff, they were quite hard to drill so god knows whats inside them but it seems unnecessary and maybe the reason they clogged in the first place.

Yeah I used cheap fluid but everything is nice and clean and it was never a problem on my focus (2005), fiesta (2013) and jazz mk3 (2018).
