Is your shower head spraying water unevenly, or worse—barely at all? If so, chances are you’re dealing with a hard water buildup. It’s a super common issue, especially in areas with mineral-rich water. But the good news? You can easily fix it at home with a few household items. In this article, we’ll walk you through how to descale a shower head blocked by hard water, step-by-step.

Why Is Your Shower Head Clogged?
Let’s start with the root of the problem: hard water. Hard water contains high levels of minerals like calcium and magnesium. Over time, these minerals can build up in your plumbing fixtures—especially the small holes in your shower head—leading to low water pressure, uneven spray, and even mold.
This is called limescale or mineral buildup, and it’s the reason your once-glorious shower now feels like a weak drizzle.
Signs Your Shower Head Needs Descaling
Not sure if hard water is the problem? Look for these telltale signs:
-
Weak or uneven water flow
-
White, chalky residue around the nozzles
-
Water spraying in strange directions
-
A blocked or dry nozzle
-
Your shower head hasn’t been cleaned in 6+ months
If you notice one or more of these, it’s definitely time to give your shower head a little TLC.
What You’ll Need to Descale a Shower Head
Before you start, gather these simple tools—most of which you probably already have:
-
White vinegar (the hero of the story)
-
A plastic bag (quart-size works great)
-
A rubber band or zip tie
-
An old toothbrush
-
A paperclip or needle (optional)
-
A wrench (if you want to remove the shower head)
-
A towel or rag
Pro Tip: For stubborn buildup, consider using a commercial shower head descaler available on Amazon.
Step-by-Step: How to Descale a Shower Head
There are two main ways to descale a shower head: with it on or off the pipe. Both work well, so choose what fits your comfort level.
Method 1: Descale Without Removing the Shower Head
This is the easiest and most popular method.
Step 1: Fill a Bag with Vinegar
Pour white vinegar into a plastic bag—about halfway full.
Step 2: Secure the Bag Around the Shower Head
Place the bag over the shower head so the nozzles are submerged in the vinegar. Secure it tightly with a rubber band or zip tie.
Step 3: Let It Soak
Let the shower head soak for 6–12 hours (overnight works best). The vinegar will break down the limescale.
Step 4: Remove the Bag and Scrub
Take off the bag and scrub the nozzles gently with an old toothbrush to remove loosened mineral deposits.
Step 5: Rinse and Run Water
Turn on the hot water to flush out any remaining debris. Done!
Method 2: Descale After Removing the Shower Head
If the buildup is severe, this method gives a deeper clean.
Step 1: Remove the Shower Head
Use a wrench to unscrew the shower head from the pipe. Wrap it in a towel first to avoid scratching the finish.
Step 2: Soak in Vinegar
Place the shower head in a bowl filled with vinegar. Let it sit for 12–24 hours.
Step 3: Clean the Nozzles
Use a toothbrush or small needle to gently unclog each nozzle.
Step 4: Rinse and Reattach
Thoroughly rinse with water, screw the shower head back on, and run hot water for a few minutes.
When to Use a Commercial Descaler
White vinegar is great, but if you’re dealing with extremely hard water or frequent clogs, a commercial descaler might be a better long-term solution.
Look for products labeled:
-
Lime and calcium remover
-
Hard water stain remover
-
Shower head cleaner/descaler
These are specially formulated to dissolve mineral buildup faster and can be found easily on Amazon.

How Often Should You Descale Your Shower Head?
If you live in a hard water area, aim to descale your shower head once every 1–2 months. This will keep water flowing freely and your shower feeling fresh.
For extra protection, consider installing a shower head filter, which blocks minerals before they reach the nozzles.
