There are white or rusty spots in my Philips Avent Bottle Warmer

Updated on 2020-12-04
If you have white or rusty coloured spots in your bottle warmer, your bottle warmer has limescale build-up. Clean or descale your bottle warmer to remove the spots.
Note:  we recommend descaling the bottle warmer every four weeks to ensure that it continues to work efficiently. In hard-water areas, more frequent descaling may be necessary.

How to clean

  1. After each use, unplug the baby bottle warmer and let it cool down
  2. Remove the water from the baby bottle warmer for hygienic reasons
  3. Wipe the outside and inside of the baby bottle warmer with a moist cloth
Do not use abrasives, anti-bacterial cleaning agents, chemical solvents or sharp tools to clean the baby bottle warmer.

Note: if you use the baby bottle warmer to warm containers of baby food, make sure that no spilled baby food remains on the bottom of the baby bottle warmer.

How to descale

  1. Mix 60 ml (2 oz) of white vinegar with 120 ml (4 oz) of cold water to descale your bottle warmer.
  2. Pour the solution into the bottle warmer.
  3. Switch on the bottle warmer and select the milk-warming setting for contents under 180 ml (6 oz) setting and let the appliance operate for 10 minutes.
  4. Leave the solution in the bottle warmer until all scale has dissolved.
  5. Pour away the solution and rinse the warmer with tap water. If you still see traces of scale after rinsing, repeat the descaling procedure.

Note: you can also use citric-acid-based descalers.
Note: Do not use other types of descalers.
