Hi all,

I've noticed that the jets on my car seem to be somewhat weak, I seem to get more water on the bonnet than on the actual windscreen.

That said, I have no idea how powerful they should be in normal circumstances.

From googling around it seems like as a first pass, I should investigate cleaning filters on the pumps etc. which is fine, but, I'm just now embarking on this voyage of self-maintaining my car and so I was wondering how big of a job it is.

If anyone has any input or links to share, YT videos or any words of advice I would be most grateful.

Thanks in advance!

Alright, going to answer my own question. That didn't take long at all. Found a post on another forum and set to work. In under an hour I managed to:
  • Remove the bottle from the car.
  • Remove the severely gunked up filters
  • Clean out the bottle (as best I could)
  • Replace the now spotless filters
  • Replace the bottle in the car
The jets work like a dream now, I think, certainly a lot better than before. See pics below. All feedback welcomed.

Before:
Filters and the inside of the bottle

After:

Wasn't able to get to all of the grime but I'll probably use another method next time, maybe agitate it with ball bearings or something.

The end result (please do let me know if this is how it should be)

Done much the same job myself. Currently have three out of four jets working fine (passenger near side doesn't work)
Quite how the wash bottle gets so full of crud I don't understand.

Most likely because at some stage, someone has not been putting washer fluid in it. Here in the tropics thats a bad idea. plain water goes off moldy black sludge eventually clogs everything up.

Pop some Milton tablets or liquid in the bottle, that will soon clean it up. A few cycles in the dishwasher also works as long as your better half doesn’t catch you.
I used her grey eliminator shampoo, and I got caught... Sleeping on the the couch is more comfortable than I expected... :thumbsup:
