How to Clean a Shower Head (NZ Homes): Step-by-Step

Weak spray, spotty limescale, a faint mouldy smell — an overdue shower head is one of the most overlooked jobs in an NZ bathroom. Here’s how to clean a shower head properly, the low-tox way.

How Do You Clean a Shower Head?

The easiest way to clean a shower head is to soak it in a concentrated enzyme cleaner for 15-30 minutes, scrub the nozzles with an old toothbrush, then rinse under hot water. For a fixed shower head, seal the solution over the head in a sandwich bag instead of removing it.

It’s one of the most skipped jobs in an NZ bathroom, mostly because it’s easy to forget a shower head needs cleaning at all. But mineral deposits and soap residue build up inside the nozzles fast, and a proper soak fixes it in minutes.

  1. Mix your solution. Dilute a concentrated enzyme cleaner in warm water in a small bowl, or in a sandwich bag if the head is fixed.
  2. Submerge the shower head. Fully dunk a removable head, or seal the bag around a fixed one with a rubber band so it’s completely covered.
  3. Leave it to soak. 15-30 minutes for light buildup, up to an hour if it’s heavily clogged with limescale.
  4. Scrub the nozzles. Use an old toothbrush to work loose any mineral deposits still stuck in the holes.
  5. Rinse thoroughly. Run it under hot water and wipe dry with a microfibre cloth.
  6. Run the shower briefly before you use it properly, to clear any last residue from the lines.

How Often Should You Clean a Shower Head?

Most NZ homes should clean their shower head about once a month to keep water flowing freely and stop mould building up in the warm, damp nozzles. In hard-water areas, or busy households with several people showering daily, clean it every two to three weeks instead.

A monthly soak is enough for most homes to stay ahead of mineral buildup. If you notice the spray splitting sideways or pressure dropping off between cleans, that’s a sign your household needs a slightly tighter schedule than the general rule.

Signs Your Shower Head Needs Cleaning

An uneven or sideways spray, noticeably weaker water pressure, white or greenish crust around the nozzles, and a faint musty smell when the water first runs are the clearest signs a shower head is overdue for a clean.

  • Water sprays unevenly or shoots off at odd angles
  • Water pressure feels noticeably weaker than it used to
  • White or greenish crust visible around the nozzles
  • A faint musty smell when the water first turns on
  • It’s been more than a month since you last checked it

Removable vs Fixed Shower Heads: Does the Method Change?

Not really — only how you contain the cleaner. A removable head can be unscrewed and fully submerged in a bowl of diluted enzyme cleaner. A fixed head stays in place and gets the same soak inside a sealed sandwich bag, tied around the neck with a rubber band.

Either way, the soak time, scrub, and rinse steps are identical. The bag method works just as well as a bowl as long as the whole head, especially the nozzle plate, stays fully submerged for the full soak.

💡 Stephanie’s Tip

Keep an old toothbrush under the bathroom sink just for this job. It gets into the nozzle holes far better than a cloth, and you won’t be tempted to use your good scrubbing brush on it.

💡 Did You Know?

Auckland’s water is naturally on the softer side compared to many parts of NZ, but every home still builds up mineral deposits over time — which is why shower heads need regular attention no matter what your water’s like.

Frequently Asked Questions

How long should I soak a shower head to descale it?

For light buildup, 15-20 minutes in a concentrated enzyme cleaner is usually enough. If the nozzles are heavily clogged with limescale, leave it soaking for up to an hour, then scrub gently with an old toothbrush before rinsing.

Can I clean a shower head without removing it?

Yes. Fill a sandwich bag with diluted enzyme cleaner, seal it around the shower head with a rubber band so the head is fully submerged, and leave it to soak for 15-30 minutes before rinsing thoroughly.

Why does my shower head keep losing pressure?

Mineral deposits and soap residue build up inside the nozzles over time and physically block the small holes water passes through. Regular cleaning, monthly for most homes, clears this buildup and restores full pressure.

Is a mouldy or clogged shower head bad for your health?

It can be. Warm, damp nozzles are an easy breeding ground for mould and bacteria, and a clogged shower head sprays water unevenly across your skin instead of rinsing it away properly. Regular cleaning keeps this in check.

Can I use bleach on my shower head?

It’s best avoided — bleach can degrade rubber nozzles and metal finishes over time. A concentrated enzyme-based cleaner descales just as effectively without the harsh fumes or long-term damage.

The Bottom Line

A shower head is one of the easiest bathroom fixtures to forget, and one of the quickest to fix. A monthly soak in an enzyme cleaner, a quick scrub with an old toothbrush, and a good rinse is usually all it takes to bring the pressure back and keep it hygienic between deeper bathroom cleans.
