Windscreen washer jets.???

[Nine468]

Im sure this has been covered before , but couldnt find the thread.
Anyway. Im having a challenge with my washer jets, or should that be washer tank....
The filters in the tank seem to be blocking up...
The pump works but nothing squirts out of the jets.. FRONT screen ONLY.
The rear screen and headlight jets still work perfectly...
Has anybody successfully cleaned out there washer bottle/tank. If so how did you do it.
Ive tried back flowing the washer jet pipe to no availe....
Also adding bleach to the washer bottle, then back flushing the bottle to get the bleach out,, still no joy,
I realy dont want to delve into the inner wing area as it means removing lots of underbodywork, and im not sure if ill still be able to access the tank..
Thanks...

check the pipework to your spray heads to see how far you have water to,one spray head on mine was blocked (which also stopped water getting to the other one) I cleared with a quick blast of compressed air

Well fingers crossed it seems ive managed to sort the problem out.
Ive put some descaling fluid into the screen wash bottle, left it for a while to do its job, then back flushed the bottle both with a thin water hose and blasting compressed air down the jet pipe...
So far so good....
But i expect it to return at some point, as ive not removed the bottle fully and it will still have some sediment in... ::) ::) ::)
