Showerhead Cleaning for Legionella Control: Practical Routine

Showers can create aerosols, so cleaning and descaling are common control tasks in many water hygiene programmes.

The routine should be based on risk assessment findings, scale build-up, water quality, outlet use, and whether vulnerable people use the showers.

Record which showerheads and hoses were cleaned, when, by whom, what method was used, and whether parts were damaged or replaced.

If scale returns quickly or spray patterns remain poor, investigate water quality, temperature control, hose condition, and whether replacement is more effective than repeated cleaning.

Missed shower cleaning tasks should be treated as compliance exceptions because repeated gaps can undermine the written scheme.
