Why Is Sterilization So Important?

A baby is more prone to catching any kind of illness in the first year. When milk bottles or nipples are not sterilized, bacteria, parasites and viruses gather on the surface, which makes your baby ill. Due to this, a baby can develop a mild thrush or in severe cases, diarrhea or vomiting.

While you cannot make every place 100% germ-free, by sterilizing the milk bottles and nipples, you can keep your baby healthy and safe from the bacteria and viruses. According to Market Research Store , by the year 2019, baby bottle sterilizer market CAGR growth will increase by 3.15%. In fact, according to NHS, 67% of people use steam-sterilizer to clean baby bottles.

Why Use Electrical Steam-Sterilizers ?

There are still some women who use boiling as a sterilization method. However, there are few drawbacks to it.

In boiling, you often miss the boiling point, which can damage the feeding equipment. Even if you master the temperature, after a few months of constantly boiling, there are chances that the teats will get damaged. Not to forget, the mess caused by constantly filling the large pans with distilled water.

Why Use Electrical Steam-Sterilizers

In the case of steam-sterilizers, there is little to no mess involved. The sterilizer only requires a cup of water that will produce steam and clean the feeding equipment. This method is much more effective because not only have you got a sterilizer, you have a clean storage area where the bottles can be kept for 24 hours.

How Are Sterilizers Used ?

Unlike manual cleaning, where you need a brush cleaner and an hour to clean all the nook and crannies of the bottles and teats, steam-sterilizer cleans these germs in eight to ten minutes. First of all, you need to clean all the feeding equipment in soapy hot water. This means, anything that has come into contact with breast milk or baby formula.

clean bottles and teats

The reason why you should use hot water is because it easily dissolves stubborn milk curds that might have gotten stuck at the edges of the bottle or in the nipple. It is necessary that you use a bottle brush for the cleaning process, which has a large brush at one end and small and thin brush at the other. Instead of damaging the nipple by turning it inside out, it is better to use the thin brush to clean it.

When all the feeding equipment is thoroughly cleaned, you have three choices. You can:

1. Boil the equipment

2. Put it in the dishwasher separately or

3. Use a sterilizer

While there are other methods to do it, steam sterilizers might be the best choice for cleaning feeding equipment as compared to boiling or using a dishwasher. In the case of a dishwasher, there’s a chance that any residue left from the last dish cleaning might color the bottles and nipples, and give them a bad odor.

When it comes to electric steam-sterilizers, they all operate on one system: The heating coil. The heating coil evaporates the water and pushes the steam through the rack, which circulates in the sterilizer and cleans the equipment. In the case of microwave steam-sterilizer, the steam follows the same path but without the heating coil. Microwave sterilizers are smaller in size and sterilize the equipment much faster.

Every machine has a drawback. In the case of a microwave sterilizer, it’s the size and in the case of electrical steam-sterilizer, it’s the heating coil. Rust can buildup quite fast on the rack if the sterilizer is not properly maintained. There’s a simple solution to this problem:

Home Remedy for Cleaning the Sterilizer’s Heating Coil

This remedy can be applied on all the sterilizers. The cleaner is a simple mixture of 2/3 water and 1/3 white cleaning vinegar. All you need to do is pour this mixture in the steamer and let it stand for around five to ten minutes. The rust flake will dissolve in the mixture and the coil will get cleaned itself. It is recommended that the sterilizer should be cleaned every four weeks however, according to many women; they do not face this problem until four months.
