How do you de-scale the steriliser?

You can choose one of the two methods of de-scaling:

1. Mix one sachet (10 gms) of citric acid with 200ml of water. Pour into the empty unit – Do not put lid on – Switch on for 1-2 minutes. Switch off at mains, leave to stand for 30 minutes – Drain and rinse unit. Run a full cycle with baskets/racks inside and lid on using exactly 90ml of water. DO NOT USE any descaler that is not Citric Acid.
2. Pour 100ml of white vinegar mixed with 200ml cold water into steriliser. Allow it to stand in the unit until any lime scale has dissolved – DO NOT SWITCH ON - Drain and rinse unit. Run a full cycle with baskets/racks inside and lid on using exactly 90ml of water.
