How to Safely Clean and Sterilize Baby Bottles: A Simple Guide for Parents

Keeping your baby’s bottles clean doesn’t have to be complicated — but it does have to be done right. Whether you’re a first-time parent or just want a safer routine, here’s an easy, science-backed guide to help you clean and sterilize bottles with confidence.
1. Rinse Immediately After Feeding
Milk residue dries fast and becomes difficult to remove.
Right after feeding, give the bottle a quick rinse with warm water to prevent buildup.
2. Use a Baby-Safe, Plant-Based Bottle Soap
Regular dish soaps can contain harsh chemicals and heavy fragrances that aren’t ideal for anything that goes into a baby’s mouth.
A dedicated baby bottle soap — like Newbees Plant-Based Baby Bottle Soap — is designed to:
- Break down stubborn milk fat and protein
- Rinse off easily with no slippery film
- Stay free from sulfates, betaine, parabens, dyes, and fragrances
- Be ultra-gentle and food-contact safe
Apply a small amount on a brush and clean all bottle parts, nipples, rings, and caps separately.
3. Use Hot Water & a Bottle Brush
Warm-to-hot water helps lift milk residue and improves cleaning power.
Use a long bottle brush to reach the bottom and a small nipple brush for tight spaces.
4. Rinse Thoroughly (Very Important!)
Even the safest soap should be rinsed completely.
Make sure no bubbles or foam remain on the bottle or nipple before drying.
5. Sterilize Regularly — Especially for Babies Under 3 Months
Sterilizing is necessary when your baby is:
- Under 3 months
- Premature
- Sick, or has a weakened immune system
- Water quality used for washing is not known
You can sterilize by:
- Boiling for 5 minutes
- Steam sterilizer
- Microwave sterilizer
Remember: Sterilizing does not replace washing. Always wash first, then sterilize.
6. Air-Dry Upside Down
Let bottles air-dry on a clean rack.
Avoid towels — they can introduce lint and bacteria.
7. Replace Old or Damaged Nipples
If nipples become cloudy, cracked, or sticky, replace them. These signs mean the silicone is wearing down.
