If your shower feels more like a light drizzle, your shower head may be clogged with hard water buildup. When mineral-rich water evaporates, it sometimes leaves behind calcium and magnesium deposits that block the nozzles and reduce water flow. CLR Calcium, Lime & Rust Remover can help remove that buildup and restore a more even spray.
Why You Should Clean Your Shower Head Regularly
Mineral deposits and limescale can build up inside shower head nozzles over time, reducing water pressure and causing uneven spray. In hard water areas, this buildup can also leave white or green crust on the surface. Cleaning your shower head regularly helps keep water flowing properly and can help prevent buildup from getting worse over time.
Pro Tip: If your water pressure starts to weaken or you notice uneven spray patterns, it may be time for a deep clean.
What You’ll Need
Before cleaning your shower head, gather a large clean bowl, cold water, an old toothbrush, and CLR Calcium, Lime & Rust Remover. If you plan to remove the shower head, make sure you have enough space to soak it safely and reattach it afterward.
Shower Head Cleaning Guide Step-by-Step Using Calcium, Lime & Rust Remover
There are two ways to clean a shower head with CLR Calcium, Lime & Rust Remover. You can remove the shower head for a more thorough soak, or clean it while it is still attached. Both methods help break down hard water buildup and clear blocked spray holes.
Option 1 — Removing the shower head
- Remove shower head
- Mix Calcium, Lime & Rust Remover with water in a large, clean bowl
(50/50 mixture) - Soak the shower head for 2–3 minutes (The foaming bubbles mean it's working!)
- Use an old toothbrush to scrub away the heavy crust
- Rinse the shower head and brush with cold water
- Reattach your clean shower head
Why this works: Soaking the fixture directly in a CLR® solution dissolves mineral buildup inside and out. It’s one of the most effective ways to clean a shower head clogged with calcium or rust. A short soak is usually all it takes to restore full spray performance.
Option 2 – Leaving the shower head attached
- Mix Calcium, Lime & Rust Remover with water in a large, clean bowl
(50/50 mixture) - Hold the bowl so that the shower head is completely submerged
- Let the shower head soak for 2–3 minutes
- Use an old toothbrush to scrub away the heavy crust
- Rinse the bowl and refill with cold water
- Let the shower head soak in the clean water for 2 minutes
- Turn on the shower and let cold water run for 1 minute
Repeat either option once a month for a full-pressure shower and a clean shower head.
Always read label instructions before use.
How Often to Clean a Shower Head
Regular cleaning shower heads should be part of your monthly bathroom cleaning routine. However, frequency can depend on your local water quality and usage habits:
-Hard water areas: Every 3–4 weeks
-Soft water areas: Every 2–3 months
-Households with multiple showers: Every 6–8 weeks
Consistent upkeep helps maintain strong water pressure and prevents limescale buildup before it becomes visible.
Signs Your Shower Head Needs Cleaning
Wondering when to clean it next? Look for these indicators:
-Water sprays unevenly or at strange angles
-Pressure feels noticeably weaker
-The shower head face looks white, green, or crusty
-A musty or metallic odor when you turn on the water
If you notice one or more of these issues, it’s time to follow the steps above on how to clean a shower head thoroughly.
Before You Start
Always read label instructions before use. Use a clean bowl, follow the recommended 50/50 mixture, and rinse thoroughly with cold water after cleaning.
What to Avoid
Do not let mineral buildup sit too long before cleaning, since heavier deposits can be harder to remove. Do not skip the rinse step after soaking, since rinsing helps flush away loosened residue. For best results, use the product only as directed on the label.
Keep Your Shower Head Working Properly
A clean shower head can help improve water flow and reduce the buildup that blocks spray nozzles. Whether you remove the fixture or clean it in place, regular maintenance can help keep your shower working properly.
