How to Descale a Shower Head
Restore blocked shower jets by soaking the head in white vinegar or a citric acid solution. For light scale, use the bag-on-shower method; for heavy scale, remove the head and soak the faceplate.
Quick answer
For light scale, tie a bag of undiluted white vinegar over the fixed shower head and soak for 30–60 minutes. For heavy scale, remove the head and submerge it in a bowl of vinegar or citric acid solution (1 tbsp per 500 ml water) for 1–2 hours. Rinse and run hot water for 30 seconds before use.
Limescale blocks shower jets and reduces water pressure. You can clear light scale without removing the head; heavy build-up needs a soak in a bowl so you can scrub the faceplate and individual nozzles.
What you’ll need
- White vinegar or citric acid powder
- Strong plastic bag and elastic band
- Bowl or basin
- Old toothbrush
- Soft cloth
Step by step
- 1
Choose your method
Use the bag method if the head is lightly scaled and fixed to the hose. Use the bowl method if the jets are heavily blocked or the head has a removable faceplate.

Bag method
Fill a strong plastic bag with enough white vinegar to cover the face of the shower head. Slide it over the head and secure with an elastic band. Leave for 30–60 minutes. For chrome or nickel-plated heads, limit soaking to two hours maximum.

Bowl method
Remove the shower head and place it face-down in a bowl. Cover with undiluted white vinegar, or a citric acid solution made from 1 tablespoon of powder per 500 ml of warm water. Soak for 1–2 hours. Citric acid is gentler on chrome than vinegar.

Scrub and rinse
Lift the head out and scrub the faceplate gently with an old toothbrush. For rubber nozzles, rub them with your finger rather than poking with a pin. Rinse thoroughly under the tap.

Flush the pipes
Reattach the head and run the shower on hot for at least 30 seconds before stepping in. This pushes dislodged scale out of the pipes rather than onto you.

Prevent future build-up
In hard-water areas, repeat the bag method for 20 minutes once a month to keep jets clear.
Do not soak chrome or nickel-plated shower heads in undiluted vinegar for more than two hours; acid pitting will dull and damage the finish. Never mix bleach with acids or ammonia, and check whether any cleaning product contains bleach before adding vinegar. Follow the product label.
Common mistakes
- Leaving a chrome head soaking in neat vinegar overnight, which causes visible pitting and dulling.
- Skipping the post-soak hot flush, so loosened scale debris clogs aerators or lands on skin during the next shower.
- Poking rubber nozzles with a metal pin when they are designed to be rubbed clean with a finger.
Frequently asked
How often should I descale my shower head?
In hard-water areas, descale monthly using a 20-minute vinegar bag soak. In softer-water areas, every two to three months is usually enough.
Can I use citric acid instead of vinegar to descale a shower head?
Yes. A solution of 1 tablespoon of citric acid per 500 ml of water works faster than vinegar and is gentler on chrome and nickel finishes.
My shower head is still blocked after soaking — what should I try next?
Remove the faceplate if possible and soak the parts separately. Check for debris inside the swivel joint or filter washer. If the head is old and the nozzles are eroded, replace it.
