Filter for windscreen washers

I'm sick of my washers blocking up. :bad-words:

I obviously have something inside the bottle, but it's tucked away inside the guard, and looks like a head-fark to remove. I can clear the jets, blow all the lines, flush the lines using the pump, and one or more jets will be blocked again by the second time I want to use them.

So I'm contemplating putting a filter in the line to the jets, to catch the crap before it reaches the jets. The only thing I can think of is a fuel filter, which will require adapting to fit the washer lines.

Anybody have any ideas on another source of in-line filter that will suit typical windscreen washer hoses?

get a fuel filter from your mower shop there alot smaller than car one

or go to your local hobby shop get one for a remote control car, plane and boat motors, there about about less than a 1" long anout 1.5cm wide and most of them are made out of steel and looks good.. and there end fitting are the same size as the washer jet pipes. plus you can clean the rc car ones.

shove your garden hose in the bottle and let all the shit bubble out the top, might be worth a try?

At the counter of every Auto One store i have been to there is a box of small filters perfect for this application.

This may be the VW in me talking but yahhhhh
German cars (VW Audi Merc....) all have small washer jet outlets and they are known for clogging up if they are not used on a regular time frame. Rear washer jets on Golfs are always clogging up. This is caused by cheap washer fluid or even dish soap being used. The factory washer fluid has a very very low alcohol content that will not dry out and clog up the jets like the cheap stuff does.
The point to my story is are you sure it is stuff in your washer bottle blocking your jets or is it cheap washer fluid drying out and clogging the jets?

The pumps that normally run the washer jets are a high volume pump and don't do well under pressure. Putting anything more then a basic strainer inline will put to much back pressure on the little pump.

So whipping some morning fresh in the washer bottle is no good ay? I used to buy the bug off concentrate, then i started usiing windex from work, just a bottle of windex in with a full washer bottle, but nowadays i just mix up some morning fresh and throw it in the wash bottle..

I'm reasonably confident that it's not the jets drying out - I can "clear" them with some wire, and watch them go from strong stream to dribble in seconds.

I hadn't thought too much about back pressure - I thought that a partially blocked filter could introduce problems, but I didn't consider if an unblocked filter would stuff things up.

Perhaps I need to have a go at sticking a hose into the bottle. Although I might try to syphon out from the bottom, rather than flush out through the top.

I think VN/P/Rs had small filters in the washer lines from factory... at least I think it was Commodores... I'll try to have a look tomorrow

Put some hydrocloric acid in your washer bottle, it will get rid of anything in there :D :finger: also gets rid of your paint, windscreen wipers etc
