Blu tack a component of the windscreen washer system?

This week my left hand windscreen washer jet blocked so I pulled off the jet to blow it out.
I was surprised to find that there was putty stuff around the washer jet. I am pretty sure it is Bostik Blu Tack. You can see it in the bottom of the hole in the picture.
The clips on the jet seemed intact. I blew the jet out with compressed air and put it back and it seems to work ok.
Also had a look on the right hand side jet and there was none on that side. I have read of people wedging something under the top of the jet (to angle it up slightly more so the washer fluid goes higher on the windscreen). Most of the blu tack seemed to be at the bottom of the hole rather than the top.

Has anyone found the same on their car? Any ideas why it is there?

That's not factory. A previous owner likely put it there as a quick, sloppy fix. They probably used it to try and adjust the jet's aim because the proper clip was broken or it was sitting loose. Since it works now, you're fine. Just keep an eye on it. If the aim is off or it gets loose again, you'll need to replace the jet nozzle or its mounting clip properly.
