Descale your Philips Avent Premium 2-in-1 Warmer & Sterilizer or Premium Fast Bottle Warmer every 2 weeks to help it run well and last longer.

Scale is white or brown calcium deposits that are left over from hard water evaporating in the appliance.

If you notice your appliance has a lot of scale buildup, it’s a good time to consider cleaning and descaling, even if you're still within the 2-week timeframe.
