A distorted shower spray can come from mineral buildup at the nozzles. Reduced flow can also be caused by the mixer, supply or internal components. Start with the least invasive cleaning permitted for your model.

Tools and preparation
- Soft cloth.
- A soft brush if permitted.
- The showerhead care instructions.
Cleaning agents must be compatible with the finish and nearby stone.
Time is a planning estimate, not a timed field test. Material prices vary; check the correct parts and local prices before buying.
Steps and safe checks
1. Read the cleaning instructions
Find the model and identify the nozzle type. Delta, for example, distinguishes flexible Touch-Clean nozzles from other heads. Advice for one surface should not be treated as permission to soak every model.
2. Clean the spray face
With water off and the surface cool, wipe the nozzles as directed. Flexible nozzles may allow deposits to be rubbed away; rigid openings should not be enlarged with pins or drill bits.
3. Use a permitted soak only if needed
Where the manufacturer allows soaking, use its mixture and timing. Protect finishes and surrounding surfaces. A hanging bag of cleaner is not suitable for every assembly, especially if it wets electrical shower features.
4. Rinse and inspect the spray
Remove all cleaning solution and run water to rinse. If removal was necessary, follow the installation instructions for the specific washer or threaded connection before testing for leaks.
Check the result
Check that the spray is more uniform and the connection stays dry. A head that keeps dripping after normal drainage may have a valve issue rather than a cleaning problem.
Common mistakes
Scraping plated surfaces, leaving acidic cleaner indefinitely and adding thread tape where a washer makes the seal can create new problems.
When to call a professional
Use a plumber for a loose shower arm in the wall, a leak behind the wall, damaged threads or continuing low flow after model-appropriate cleaning.
What can happen if you postpone it?
Blocked showerhead outlets can distort spray. Scraping or soaking with the wrong cleaner can damage the finish, turning a cleaning job into a replacement.
Prevent a repeat
Wipe the spray face periodically with the approved method. Address a developing restriction before deposits become difficult to remove.
