2) Faucets and chrome parts

In appliances with pressurized boilers, there are safety covers and recommendations not to open them under pressure.
Water and maintenance (to last for years)

Descalcify as recommended (for example, Kärcher suggests periodic routines).
FAQ
Does a steam cleaner replace bleach/disinfectant?
