Sterilising your baby’s bottles is a vital step to eliminating harmful bacteria while ensuring your little one is getting all the right nutrition. Here we look at various ways to keep your baby’s bottles germ-free. By Laurel Pretorius.
Today’s parents have a wide range of sterilisation options – from sensible old-fashioned boiling to modern self-sterilising bottles. Some brands even offer multiple solutions, allowing new parents to choose what works best for their daily routines, living spaces, and travel needs.
This guide provides an easy-to-follow comparison of the most common sterilisation methods, their pros and cons, and the latest innovations in the industry.
Why is Bottle Sterilisation Important?
Newborns and babies have developing immune systems, making them vulnerable to bacteria that can thrive in leftover milk residues. Proper sterilisation helps prevent infections, diarrhoea, and other illnesses. While regular washing removes visible dirt, sterilisation eliminates nearly all germs and bacteria. It is recommended that you continue sterilising your baby’s bottles until they are at least 12 months old.
Exploring the 6 most common methods of sterilisation
Let’s look at the numerous ways to sterilise baby bottles as well as the advantages and drawbacks:
- Boiling water: This traditional method involves submerging bottles and accessories in boiling water for at least 10 minutes. It’s cost-effective and requires no special equipment, but it can be time-consuming and may cause damage to the bottles over time.
- Electric sterilisers: These devices use steam to sterilise multiple bottles at once, typically in under 10 minutes. They’re ideal for families who sterilise frequently, though they do require electricity – unpredictable in South Africa at the best of times – and take up counter space. Some models even include drying functions or accessory trays for added convenience. All of this make it a popular choice for parents.
- Microwave sterilisers: Compact and efficient, microwave sterilisers work in just a few minutes and are more affordable than the electric options. Many brands offer microwave-friendly solutions, either as standalone units or as part of bottle-integrated systems. Unfortunately, these sterilisers do rely on electricity (to run the microwave) so parents would need a backup plan when there are power outages.
- Self-sterilising bottles: These clever bottles have become a game-changer for busy parents. They sterilise themselves in the microwave in just a few minutes – no separate devices required. Perfect for night-time feeds, travel, or small kitchens, they simplify bottle care without compromising on hygiene. This method is offered by several leading brands with Tommee Tippee being the only brand in South Africa currently offering a self-sterilising bottle, which is part of a wider product range that includes both electric and microwave sterilising options – giving parents more choices under one brand.
- UV sterilisation: These high-tech devices use ultraviolet light to kill bacteria without heat, steam, or chemicals. They are highly effective and portable, but tend to be expensive and can only sterilise one bottle at a time.
- Chemical cold-water sterilisation: This method involves dissolving sterilising tablets or liquid in cold water and soaking bottles for at least 15 minutes. It is useful for travel or areas with limited electricity, but it requires careful rinsing to avoid chemical residue.
Common hurdles in bottle sterilisation (and quick fixes)
While keeping baby bottles sterile is essential, as new parents, the process of daily sterilisation can feel somewhat overwhelming. Here are a few common obstacles parents may face and some easy solutions:
- It’s time consuming: Traditional methods can be laborious, especially for parents who need to sterilise multiple bottles daily. Try self-sterilising bottles or electric options to save time.
- Space limitations: Large electric sterilisers require countertop space, which may not be ideal for smaller kitchens. Compact microwave units or self-sterilising bottles are great space-savers.
- Effectiveness: Parents may question whether traditional or newer methods provide better sterilisation. All approved methods are effective when used correctly – choose what best fits your lifestyle and circumstances.
- The cost factor: Advanced sterilisation options, such as UV or electric sterilisers, can be expensive. Budget-friendly methods like boiling or cold-water sterilisation still get the job done brilliantly.
- Sterilising on the go: Some sterilisation methods are difficult to use on the go, making travel with a baby more challenging. Self-sterilisation bottles are portable and will very quickly become an on-the-go parent’s best friend.
- Urban vs. rural access: Families in rural areas may have small budgets and limited access to electricity or sterilisation equipment. Boiling water remains a simple and safe, electricity-free solution – and this goes for all South African parents stuck with dirty bottles during a power outage.
Expert tips and new innovations
With evolving technology and expert insights, bottle sterilisation has become more efficient and user-friendly. Here’s what parents should know:
How often you should sterilise bottles
Bottles should be sterilised after every use. As your baby grows, daily sterilisation becomes less critical, and regular washing with hot, soapy water may be enough.
Keeping bottles germ-free
Even after sterilising, bottles can quickly become contaminated if not stored correctly. Store them in a clean, sealed container to maintain good hygiene.
South Africa’s R991 legislation highlights the importance of proper sterilisation and safe feeding practices. These regulations mean that feeding products meet strict hygiene standards. Parents should always follow best practices to reduce the risk of bacterial contamination.
Caring for your steriliser and bottles
Regular maintenance will see your steriliser and bottles lasting much longer. Always follow manufacturer guidelines, descale electric units when needed, and check that bottles and teats remain in good condition.
Not all bottles are created equal
High heat can degrade certain plastics over time. Either choose the right baby bottles for your sterilisers or the right steriliser for your baby bottles.
Evolving sterilisation methods
Affordable modern innovations like Tommee Tippee’s self-sterilising bottles are part of a growing trend that empowers parents from all walks of life with an efficient, space-saving and travel-friendly solution.

- Sterilising for twins or multiples? Consider a high-capacity electric steriliser or quick, efficient self-sterilising bottles – in and out of the microwave in minutes.
- Short on kitchen space? A microwave unit or self-sterilising bottles are best for you.
