Medela microwave bags use steam to kill germs, common bacteria and yeast quickly and easily, similarly to a steam steriliser or bottle steriliser that use steam to disinfect breast pump parts and other accessories. As with all other sanitising methods, there’s a bit of prep to do – simply rinse the items you want to sanitise with cold, clean water, then clean with warm, soapy water before rinsing again. Next add a little water to the bag, along with your parts, and seal. Pop in your microwave and heat according to the instruction manual (a minimum of three minutes). Once done, carefully remove the water and the parts from the bag and dry with a clean cloth: for full instructions, see the product packaging.

Yes, each Quick Clean™ Microwave bag can be used up to 20 times, which means they’re economical as well as convenient. There’s even a handy panel of numbered boxes on the front of each one so you can keep a record of how many times you’ve used it – a smart idea for busy mums, particularly if you’re breastfeeding and working full time.
