Descaling the base unit

Just like all appliances with water heating elements, calcium deposits or
scale may build up after the water evaporates. Scale is non-toxic, but if left EN unattended, can hinder appliances’ performance. Descaling your Wabi Baby
sterilizer when needed helps maintain and extend the life time of the heatingh
element. Depending on the mineral content of your water, calcium deposits may
build up faster, making it necessary to descale more often. 

TIP: The mineral content of water varies greatly by region, so we always recommend using distilled water to slow down scale buildup.

Step 1: Choose one of the following method depeding on your model and preference.

METHOD 1 - USING DESCALING MODE

  2. Add 1 teaspoon of citric acid powder to the water.
  3. Place the Chamber on the Electric Base Unit, then close the Lid. Please make sure that no other items are inside the Chamber.
  4. DESCALING No-scrub descaling with citric acid.
  5. The descaling mode takes 35 minutes—5 minutes of heating the cleaning solution and 30 minutes of cooling.
