How do I remove the white/brown spots on my Philips Avent sterilizer's heating plate?
Published on 30 November 2022
The white/brown spots are limescale. They build up in appliances as the residue of minerals naturally contained in water, which fail to evaporate when water is heated. The harder the water, the faster scale builds up. Although it is not harmful as much, it is unsightly, hard to clean and can impair the operation of appliances or damage their components if allowed to build up. It is recommended to descale the sterilizer at least every 2 weeks to ensure it works efficiently. Follow the instructions below on how to properly descale your device.
Step by step instructions
Pour 12ml/0.5oz of white vinegar (5% acetic acid) and 120ml/4.5oz of water into the water reservoir.
Wait for 6 hours or overnight for best results, or until all the limescale has dissolved.
Empty the water reservoir and rinse it thoroughly.
If you still see traces of scale, remove it by sponge. Rinse again and wipe the base with a damp cloth.
Note: Use only citric acid based descalers and avoid all other types.
