Hi.
Janets 1999 CR-V has blocked washer jets but the old pin remedy is doing nothing. I have just put them is a small container of neat Viakal descaler but it's quite viscous so I don't know if it will flow into the depths of the jets. Do you think that this will make a difference? What else would you recommend? New jets, obviously...
Thanks.
I use my little ultrasonic cleaner.
Ooooh, sounds like a toy I might like to buy...
Angle grinder.
Wrong group.
It happens that Mike Barnard formulated :
Are you certain it is only the jets which are blocked? Sometimes the pipes, filter and bottle can choke up with that horrible jelly like growth. Clean all that out first, before blaming the jets.

A very long soak in the Harpic toilet limescale remover did wonders for our shower head, and might do the trick for you?
Any decent garage has a set of little wire things that are inserted into the jets. Pop in and ask if he can clean the jets for you. Otherwise, it is the angle grinder.

In case anyone is interested, after 15 hours soaking in Vaikal nothng changed. Oh well.
However you fix the problem the way to avoid a recurrence is to use a proper screenwash additive. Washing up liquid etc causes various bacterial gunge to accumulate, hence the blocked jets.
Presumably that would only have helped if the blockage was limescale?
Have you tried blowing it through with an airline?

I only ever use proper additive - and have often got problems with blocked jets on one car. And looking at them, it appears to be the hard water causing the problem.
No, I haven't. I'll give it a go.
We always have a 50% (ish) mix of water and Halfords blue additive. The water round here is very hard though.
Does water come through the pipes with the jets removed ?

Yes, in floods. It's the jets not the pump, fuse, filter or piping. Thanks anyway.
You might be able to get one from a scrapyard for a pound or so. Worked for me when descaler and an ultrasonic bath did nothing useful. It may incorporate a one-way valve which has turned into a no-way valve. Don't forget to secure the tube to the washer jet with something like a cable tie, or it /will/ come off.
Yes indeed; in my experience the problem is usually biological activity, nothing to do with limescale.
Why not buy a couple of new ones. They should only be a couple of quid each unless they are heated.
