How often should you clean a showerhead?
Updated July 2026
Descale a showerhead every 3 to 6 months, dropping to monthly if your water is very hard. All it takes is a soak in white vinegar for 30 minutes to overnight, which dissolves the mineral scale that plugs the nozzles. Left alone, that scale turns a full spray into a weak, splitting, sideways-shooting mess, and the standing water inside a neglected head can harbor bacteria. A replacement head runs $20 to 80, but cleaning usually restores the one you have.
What changes the interval
| Your situation | Interval | Why |
|---|---|---|
| Soft or softened water | Every 6 months | Little scale forms, so descaling is infrequent |
| Moderately hard water | Every 3–6 months | Minerals slowly plug the nozzles and split the spray |
| Very hard water (7+ grains) | Monthly | Scale cements the jets shut within weeks |
| Spray is weak, uneven, or spitting sideways | Descale now | Clogged nozzles are the classic hard-water symptom |
| Guest or rarely used shower | Descale and flush | Standing water in a stagnant head can grow bacteria |
The cost of skipping it
What skipping it costs: scale is mostly a nuisance rather than a disaster, but it compounds. Blocked nozzles cut flow and comfort, and people often toss a perfectly good head for $20 to 80 when a $3 jug of vinegar would have fixed it. Hard-water scale also builds behind the head in the arm and valve, where it is harder to reach. Descaling every few months keeps the spray strong and flushes the standing water where bacteria can settle. See the full step-by-step method.
How to do it (5 minutes active · DIY with white vinegar)
- Fill a sturdy plastic bag with white vinegar (enough to submerge the face of the head).
- Secure the bag over the showerhead with a rubber band or hair tie so the nozzles sit in the vinegar.
- Soak 30 minutes for light scale, up to overnight for heavy hard-water buildup (avoid overnight on some plated or brass finishes).
- Remove the bag, then scrub the nozzles with an old toothbrush and rub the rubber jets with a thumb to pop scale loose.
- Run hot water through the head for a minute to flush out loosened mineral bits.
- For a deep clean, unscrew the head, soak it fully in a bowl, and clear the inlet screen or flow restrictor of grit.
Knowing the interval is the easy half. OnOtto reminds you at the right interval, and it won't let you snooze it into next year. Tasks persist until they're done, and completing showerhead descaling schedules the next one automatically.

Can I clean a showerhead without removing it?
Yes, and it is the easiest way. Fill a plastic bag with white vinegar, slip it over the showerhead so the nozzles are submerged, and tie it in place with a rubber band. Soak 30 minutes to overnight depending on how heavy the scale is, then scrub the jets and flush with hot water. Only unscrew the head if you want to clear the inlet screen or flow restrictor too, or if the finish warns against long vinegar contact.
Will vinegar damage my showerhead finish?
Plain chrome, stainless, and most plastics handle a vinegar soak fine. The exceptions are certain coated, brushed-nickel, oil-rubbed-bronze, or brass finishes, where a long soak can dull or discolor the coating. For those, keep the soak short (30 minutes, not overnight), rinse well afterward, and check the manufacturer's guidance. If you are unsure, test on a small area first. Never mix vinegar with bleach, and skip harsh acids that can etch the metal.
Why is my showerhead spray weak even after cleaning?
If descaling the nozzles did not restore the flow, the blockage is upstream. Check the small inlet screen or the flow restrictor where the head meets the arm, since scale and grit collect there and choke the whole head. A partly closed valve, a clogged whole-house filter, or genuinely low household pressure can also be the cause. Rule out the head first, then work back toward the valve and the home's overall water pressure.
