The best bottle steriliser

When it comes to buying a bottle steriliser, the options really can seem endless – do you go for seam, microwave or electric? And even then, which brand should you buy? To make things easier, we’ve found the best bottle sterilisers on the market to help you make the best decision.

Firstly, let’s take a look at how each different steriliser works, and the pros and cons of each.

1. Electric steam sterilisers

As the name suggests, these clean your baby’s bottles, dummy and breast pump by using steam to kill germs. This will need to be plugged into the mains, and works like a kettle – heating the water, which turns into steam and sterilises the items inside.

The pros: Steam sterilisers are now being developed with fast cycles, which is always a winner. This is a great option if you don’t have a microwave in your kitchen.

The cons: You will need to clean or descale the elements every few weeks which can be time consuming. Electric steam sterilisers can also be quite bulky, so if you’re pushed for space in your kitchen, this might not be the best option for you.

2. Microwave steam steriliser  

These also use steam to sterilise your baby’s bottles/your breast pump, yet unlike electric sterilisers, they do not need to be plugged in and work in the microwave. Once you’ve added water, the bottles and the over, you can simply pop these sterilisers in the microwave.

The pros: These take up a lot less space than electric sterilisers and do not need to be left out all the time. They do the job quickly and are much easier to clean.

The cons: You’ll need to make sure the steriliser will fit in your microwave, as some of them can be quite bulky.

3. Cold water steriliser

Like its name suggests, a cold-water steriliser uses a sterilising tablet or liquid and cold water to sterilise bottles or feeding equipment submerged in it.

The pros: A silent sterilising option if you’re up in the middle of the night, a huge plus of using a cold-water option is that your equipment will stay sterilised as long as they are submerged in water. When using steam sterilisers, once the lid has been opened, the bottles are no longer sterile.

The cons: Unlike steam sterilisers, when using cold water methods, you’ll need to wait up to 15 minutes.

4. Travel sterilisers

These are usually microwave steam sterilisers, but on a smaller scale which is perfect if you’re on the move. Whether it’s that first family holiday, or just a weekend with the grandparents, these usually only fit one or two bottles.

The pros: These can usually be used both in the microwave and with cold water tablets (which is a good backup when staying in hotels).

The cons: You won’t be able to fit too much in, so might find you’re constantly using it depending on how young your baby is.

5. Self-sterilising bottles

A bottle that cleans itself? It might sound too good to be true, but these work in similar way to the microwave steam sterilisers. Simply fill the base of the bottle with cool water and pop it in the microwave.

The pros: Super easy to use, this is a great option when you are on-the-go and means you don’t have to carry any extra equipment with you.

The cons: Obviously you are only sterilising one bottle at a time, so a larger steriliser might be more efficient.

6. UV Bottle Sterilisers

Never heard of a UV steriliser before? Neither had we. These gadgets are new on the market and innovating, in that they don't use water, steam, or chemicals at all to sterilise bottles or dummies. They use special LED lights to emit UV, killing off bacteria safely and quickly. 

The pros: Easy to use, with no mess or water required. 

The cons: The most expensive option of all bottle sterilisers.

The best electric steam sterilisers

Without taking up too much room on the kitchen counter, our mums loved how quick and easy this was to use, keeping bottles sterile for up to 24 hours. That said, they found unplugging, emptying and refilling the steriliser to be a bit of a faff.

Tested by mum Michelle Walsh for the Mother&Baby Awards 2018: "I would recommend this to a fellow mum as it is fairly easy to use once it’s been assembled. It’s also convenient for travelling as it converts into a microwave steriliser which is handy. This particular steriliser takes up less counter space so it’s much better than the bulkier items available on the market."

Tested by mum Nicola Widger for the Mother&Baby Awards 2018: "I would recommend this steriliser to other mums because it's quick and easy to use.

Tested by mum Jocelyn for the 2020 M&B Awards: "Most sterilisers I have seen advertised, and indeed have previously used myself, have been water-based. I think the idea of a steriliser using UV light is very novel and appealing - in a way, it sounds almost futuristic and certainly more modern than the usual options. This unit is also marketed as being able to dry your wet items after you have washed them, which is appealing if, like me, you get annoyed with bottles and teats sitting around waiting to dry and taking up space. You can also the unit it to sterilise other items - an example given is a TV remote control - so it opens this item up for use beyond the baby sterilising years. This obviously means better value for money."
