Clear safe mineral buildup from faucets and showerheads
Scale can distort spray, reduce flow, hide a drip, and make fixtures harder to use.
When it usually needs attention
Ongoing home-care habit
WaterSense recommends periodic scale inspection and cleaning when buildup restricts flow.
When this guide applies
Applies when the household confirms hard water or recurring mineral scale.
What to do
Inspect for drips and scale; use only the fixture manual or EPA-permitted product category, then rinse and confirm the connection does not leak.
Applies when: Applies when the household confirms hard water or recurring mineral scale.
Who should handle it: Residents may perform surface care; fixture removal, corroded piping, concealed leaks, and unauthorized rental changes route to the responsible owner or plumber.
Tools
- Soft cloth
- Soft brush permitted by the fixture finish
Parts and supplies
- White vinegar or another fixture-manufacturer-approved descaler only when the finish permits it
- Clean water for rinsing
Safety gear
- Gloves and eye protection when the approved product label requires them
Before you start
- Identify the fixture finish and read its care instructions
- Protect nearby stone or sensitive material
Power, water, or fuel shutoffs
- Turn the fixture off; do not force a stuck supply valve
Cleaner or chemical limits
Vinegar is an acid and is not safe for every stone, metal, coating, seal, or appliance; never mix it with bleach or another cleaner.
Stop and get help when
- Stop for corrosion, a loose pipe, leak inside a wall, damaged finish, persistent low pressure, or a connection that moves
Who to call: Use the manufacturer, responsible owner, or qualified plumber for an unsafe or unresolved fixture condition.
