How to Descale a Shower Head
Part of our Showers guides.
Hard water deposits reduce flow and make spray uneven. Vinegar dissolves most of it.
| Time | 1-2 hours (mostly soaking) |
|---|---|
| Difficulty | Easy |
| Tools | White vinegar, plastic bag, rubber band, soft brush |
Step by step
- Rub the nozzles. Silicone nozzles release scale when rubbed.
- Bag soak. Fill a bag with vinegar, tie it over the head, soak 1-2 hours (shorter for matte finishes).
- Handheld. Unscrew and soak the head in a bowl.
- Brush. Scrub with a soft brush.
- Rinse. Run hot water for a minute.
Tips & common mistakes
- Test vinegar on a hidden spot on matte black or bronze finishes first.
Matte black and bronze finishes
Acidic solutions like vinegar can dull some coatings if left too long. Limit soaking to 15-30 minutes, test on a hidden area first, and rinse thoroughly. For daily care, a quick wipe with a soft cloth is enough.
Shower panels with many nozzles
Body jets and rain heads with silicone nozzles can be cleaned by rubbing each nozzle with a thumb while the water runs. For built-up scale, hold a cup of vinegar against the rain head with a bag or wipe nozzles with a vinegar-soaked cloth.
Flow restrictors and inlet screens
If the spray stays weak after descaling, unscrew the head and check the inlet screen and flow restrictor for sediment. Rinse them under the tap; don't remove the restrictor if local rules require it.
Preventing buildup
- Wipe nozzles weekly.
- Consider a shower filter or a whole-house softener in very hard water areas.
- Run hot water briefly after cleaning to flush loosened scale.

Frequently asked questions
How often?
Every 1-3 months in hard-water areas.
Can I use CLR or lime removers?
They work but are stronger than vinegar; check that they're safe for your finish and follow label directions.
How long should I soak in vinegar?
1-2 hours for chrome; 15-30 minutes for matte black, bronze or coated finishes.
Does descaling improve pressure?
Yes, clearing blocked nozzles restores spray and often makes pressure feel stronger.
What if nozzles are still blocked?
Rub them by hand or use a soft toothbrush; a pin can clear stubborn holes gently.
