generation of intelligent products from AVENT – the most
sophisticated steam steriliser you can buy and the easiest to use.
The AVENT i

Q24 Steriliser uses the intensive heat of steam to kill all

household germs helping you sterilise your baby feeding equipment
as safely and quickly as possible. There are two different modes for
greater convenience:
Mode 1 runs a single 6 minute sterilising cycle, then keeps the
contents sterile for 6 hours, providing the lid is not removed.
Mode 2 keeps contents sterile for up to 24 hours by continuously
repeating the cycle, so you can have clean, sterile bottles day 
and night.
As well as bottles and breastfeeding accessories, you can sterilise any
other boilable items (please refer to the manufacturer’s instructions
regarding sterilisation).
Please take a few minutes to read through the ENTIRE INSTRUCTION
LEAFLET before using your AVENT i

Q24 Steriliser for the first time.

Using pre-boiled or filtered water in your AVENT iQ24 Steriliser can
reduce limescale build up. You should de-scale your steriliser every
four weeks, or as often as needed in hard water areas, to ensure it
continues to work 100% effectively. 
EITHER:
1. Mix one sachet of citric acid* (10gms) with 200ml of water. 

Pour into the empty steriliser. Do not put lid on. Activate Mode 1
and leave for 1-2 minutes. Unplug and leave to stand for 30
minutes. Drain and rinse the inside of the steriliser. Then in 
Mode 1, run a full sterilising cycle empty with the lid on, using
exactly 90ml of water. Drain and wipe dry. 

OR:
2. Pour 100ml vinegar mixed with 200ml cold water into the steriliser.

Allow to stand in the unit until any limescale has dissolved. 
Drain and rinse the inside of the steriliser thoroughly. Wipe dry.

*Citric Acid is available from most chemists – avoid contact with eyes
as this may cause irritation. Keep out of reach of children.
