Collects limescale inside your kettle as water boils Stainless steel wire mesh - durable and rust resistant Confirmed food safe for everyday kettle use Compatible with all kettle types - electric and stove-top Reusable - rinse or soak to restore between uses No chemicals, no installation, no effort required Stainless Steel Kettle Descaler Ball for Limescale-Free Boiling How It Works: The Steelex HK4401 kettle descaler is a stainless steel wire mesh ball that sits in the base of your kettle and attracts limescale deposits as the water heats. Rather than letting calcium and mineral build-up coat the heating element or kettle walls, the ball draws the deposits onto its mesh surface, keeping your kettle cleaner between deep cleans. Food Safe and Reusable: Made from stainless steel wire mesh, this descaler ball is confirmed food safe and suitable for use in kettles used daily for drinking water. It is reusable - simply rinse or soak it in a mild descaling solution periodically to restore its effectiveness, then return it to the kettle. Compatible with All Kettle Types: The ball works in electric kettles, stove-top kettles, stainless steel kettles, and plastic kettles. No fitting, fixing, or installation is required - place it in the kettle and it begins working straight away.
