Learn the best way to clean and care for your Pura stainless baby bottle with our step-by-step guide, including tips for removing milk residue and sterilizing.
Pura stainless baby bottles are a fantastic choice for eco-conscious parents who want a durable, safe, and sustainable option for their little ones. Unlike plastic bottles that can harbor odors and stains, stainless steel is naturally resistant to bacteria and doesn't leach chemicals. But to keep your bottle in top condition and ensure your baby's health, proper cleaning and maintenance are essential.
In this guide, we'll walk you through the best practices for cleaning your Pura bottle, from daily rinsing to deep cleaning and sterilization. We'll also share tips on removing stubborn milk residue and keeping the bottle looking and smelling fresh. Whether you're a new parent or a seasoned pro, these steps will help you get the most out of your Pura bottle.
Why Proper Cleaning Matters
Stainless steel is non-porous, which means it doesn't absorb odors or flavors like plastic can. However, milk residue and bacteria can still build up if not cleaned properly. Regular cleaning not only extends the life of your bottle but also ensures that every sip is safe and fresh for your baby.
Pura bottles are designed with minimal parts to make cleaning easier, but it's still important to pay attention to every component, including the nipple, collar, and any straw or sippy spout. Proper care also prevents mineral deposits from hard water and keeps the stainless steel shiny.
- Always disassemble the bottle completely before cleaning.
- Use a bottle brush with soft bristles to avoid scratching the stainless steel.
Step-by-Step Cleaning Instructions
Start by rinsing the bottle and all parts with warm water immediately after use. This helps remove milk residue before it dries and becomes harder to clean. Then, wash each part with mild dish soap and warm water, using a bottle brush to scrub the inside and a small brush for the nipple and straw.
For a thorough clean, you can also use a mixture of baking soda and water to gently scrub any stubborn spots. Avoid using abrasive cleaners or steel wool, as they can scratch the surface. Rinse everything thoroughly to ensure no soap residue remains.
- Use a dedicated bottle brush for the inside of the bottle.
- For straws, use a straw cleaner to reach the entire length.
Removing Milk Residue and Odors
Sometimes milk residue can cling to the bottle, leaving a film or odor. To tackle this, fill the bottle with a solution of warm water and a tablespoon of baking soda, and let it soak for 15-20 minutes. Then, scrub as usual and rinse well.
Another effective method is using white vinegar. Mix one part vinegar with three parts water, soak the bottle, and then wash thoroughly. This not only removes residue but also neutralizes any lingering smells. Remember to rinse very well to avoid any vinegar taste.
- Soak in baking soda solution for stubborn stains.
- Vinegar solution helps eliminate odors naturally.
Sterilizing Your Pura Bottle
For newborns and infants, sterilizing bottles is often recommended to ensure they are free from harmful bacteria. Pura stainless bottles can be sterilized by boiling them in water for 5-10 minutes. Make sure to remove all silicone parts, such as nipples and straws, as they may not withstand high heat as well.
Alternatively, you can use a steam sterilizer or a UV sterilizer if they are compatible with stainless steel. Always check the manufacturer's instructions for your specific bottle model to avoid damaging any components.
- Boil the bottle for 5-10 minutes for sterilization.
- Remove silicone parts before boiling to prevent damage.
Drying and Storage Tips
After cleaning and sterilizing, it's crucial to let all parts air dry completely before reassembling. Moisture can promote bacterial growth, so ensure everything is dry. Place the parts on a clean drying rack or a clean towel.
Store the bottle disassembled in a dry, clean place. Avoid storing it with the lid on while still damp, as this can trap moisture and cause odors. If you're not using the bottle for a while, make sure it's completely dry before putting it away.
- Air dry all parts thoroughly before reassembling.
- Store disassembled to prevent moisture buildup.
Caring for Different Pura Bottle Types
Pura offers a variety of bottles to suit different ages and needs, from the KikiTM 11oz Sippy Bottle for toddlers to the Big Mouth® Sport 16oz Insulated Bottle for older kids. Each type may have specific cleaning considerations, such as insulated bottles that should not be submerged in water for long periods.

For insulated bottles, avoid using a dishwasher and instead hand wash with warm soapy water. The KikiTM Kiddo Straw and KikiTM XL Sipper SpoutsTM are removable and should be cleaned separately. Always refer to the care instructions that come with your specific bottle to ensure you're cleaning it correctly.
- Insulated bottles: hand wash only, avoid soaking.
- Remove and clean straws and spouts separately.
Maintaining the Appearance of Your Bottle
Over time, stainless steel can develop water spots or small scratches. To keep your bottle looking new, dry it immediately after washing with a soft cloth. For water spots, wipe with a little white vinegar on a cloth, then rinse and dry.
If your bottle has a colored finish, avoid using abrasive cleaners that could fade the color. Pura's stainless steel is designed to be durable, but a little extra care goes a long way in preserving its appearance.
- Dry with a soft cloth to prevent water spots.
- Use vinegar to remove mineral deposits.
By following these simple steps, you can keep your Pura stainless baby bottle clean, fresh, and ready for every feeding. Regular maintenance not only ensures your baby's health but also extends the life of your bottle, making it a worthwhile investment.
