Can you fix a garden spray nozzle?

I have the trigger type, usually with the simplest end (not the 22 different spray patterns!).  But eventually they either get clogged, so that the fan spray ends up only a partial circle...
or the trigger gets sticky, so that it will stay in the partially open position, and I have to push the screw in to make it stop.

Sometimes it even won't stop dripping when I do that.

yes, I know you can adjust it somewhat by turning the nut, but I'm wondering, can you take the whole thing apart and lubricate it, or something, and declog the holes, so it sprays full-on again?  Or change the o-ring, or something...?!

I hate that I throw them away because of that, especially when they are otherwise made of metal and haven't broken or turned to a million microparticles, like plastic does.

Anybody ever tried doing this?  (I'm not mechanically inclined; I'm afraid to attempt it and kill what little life remains.)

Like most issues discussed on permaculture forums....it depends.

I have had several different sprayer attachments that were made in different ways.

Leaking at the handle I've used Teflon tape or pipe dope to fix

Leaking from the spray end is likely a rubber gasket or an o-ring. O rings are great to have on hand on a homestead and if you do not have the right size you can slice with a razor cut to size and super glue it back. Often this fix works for years.

Clogging can happen from mineral buildup and hard water deposits. If that's the issue I would try soaking the entire thing in vinegar. If this proves ineffective you could take it apart and clean the screen with something stronger or just a good brushing.

The handle actuator sticking could be a lubrication issue. Try using a food grade lubricant pen with a needle applicator if you aren't comfortable dismantling your spray head.

Good luck!

Yeah, this happens to me too. There isn't really a way to disassemble them and replace internal parts.

My lazy method is to let the nozzle dry out somewhat. Then drip some 3-in-1 oil or equivalent down into the "exit" end, and work the lever. Next I do the same for the metal plunger attached to the lever. Let it sit a while, then work it again before getting it wet. This seems to lube up the seals, and maybe swell them a little. It's crude but it works -- I've extended the life of many nozzles by years and years.
