When to clean an electric water boiler with citric acid

• As you use an electric water boiler, there may be rust-like red dots (transferred rust) on the inner surface, the interior may turn partly milk white, black, or rainbow colors, or white suspended matter (minerals) may be found in the water inside.
  These are not caused by discoloration or corrosion of the inner container itself or separation of the fluorine resin but result from actions of the minerals (such as calcium, magnesium, and iron) contained in the water.
• Although they will not pose a sanitary hazard, clean the water boiler frequently if the stains become conspicuous.
  Recommendation: Clean with citric acid once every two or three months.
