Kettles: (Check manufacturer’s instructions before use)
- Half fill kettle with water and boil (do not overfill). Unplug and place in empty sink. Slowly add 1 sachet. Leave for 10 minues. Use 2 sachets for heavy scale.
- If any limescale remains, reheat solution until it fizzes (DO NOT boil as this may cause overflow).
- Pour solution away, rinse kettle with cold water, boil again with clean water and rinse once more.
