I've seen vinegar used plenty of times without issues, but you're right to be cautious—especially if your showerhead has a special finish like brushed nickel or oil-rubbed bronze. Vinegar is acidic, so prolonged soaking could potentially dull or discolor certain finishes. Maybe test it first on a small hidden spot? Or dilute the vinegar with water to reduce acidity. I've personally never had trouble with chrome fixtures, but better safe than sorry...
"Maybe test it first on a small hidden spot?"
Yeah, good call on testing first. I've seen vinegar work wonders too, but heard some horror stories about finishes getting messed up. Anyone tried lemon juice diluted with water instead? Curious if that's gentler...
I tried lemon juice diluted once when my shower head went full sprinkler mode... it was gentler for sure, but took foreverrrr. Ended up back with vinegar—just rinsed it off quicker this time and no finish disasters yet. Fingers crossed!
Vinegar's definitely the way to go, honestly. I've managed a few properties over the years and whenever tenants complain about wonky shower heads, vinegar always does the trick quicker than anything else. Lemon juice smells nicer, sure, but waiting around forever isn't practical when you need the shower back ASAP. Just don't leave vinegar soaking too long—quick soak, scrub with an old toothbrush, rinse well—and you're golden. Haven't seen it damage a finish yet if you're careful.

Vinegar's great, but I've found that if your shower head has rubber nozzles, gently massaging them with your fingers can clear out mineral buildup pretty quickly without any soaking. Worked wonders for mine...might save you some hassle!
