The Kettle Collector helps increase the life of your tea kettle while reducing boiling time and energy costs by attracting limescale deposits that build up on heating elements. Made from fine stainless steel wire, this hygienic coiled ball provides a large surface area for calcium scale collection. Simply place it in any kettle—including electric kettles—while boiling water. After use, clean by rinsing under cold water and gently squeezing out mineral deposits. Say goodbye to white hard water scaling with this effective descaler.
