And now onto the five tips to sterilize the dropper bottle:

Start with a Good Clean

Begin sterilizing by washing your dropper bottle with hot water and mild dish soap. Make sure to clean all of the parts, including the rubber bulb and cap.

Rinse the components with hot water until all soapy residue is gone. To get rid of any stickiness, spray 70% isopropyl alcohol on the surface. Make sure to rinse the bottles twice in warm water after de-labeling to remove any remaining soap.

Boil to Disinfect

Place the glass parts (the bottle and the glass pipette) in boiling water for 5 to 10 minutes. Boil the glass only: plastic caps and rubber bulbs can warp or crack in boiling water, so wash those by hand in hot soapy water and wipe them with 70% isopropyl alcohol instead. Use tongs to remove your bottles after 10 minutes. Simply place them down on a surface to let them cool before handling them as they will be quite hot.

Rinse Once More

Once your dropper bottle has been boiled, rinse it out once more with hot water to get rid of any bacteria or germs that could have survived during the sterilization process. It can take some work, depending on how long you soaked your bottles.

Air Dry the Dropper Bottles

After sterilizing, allow your dropper bottle to air dry for at least 30 minutes before re-using. This will help ensure there are no moisture droplets left on the components, which could lead to bacteria growth in the future.

Store Appropriately

Once completely sterilized and dried, keep your dropper bottle clean by storing it in a cool place away from direct sunlight. Make sure to cover the opening with its cap when not in use.

Conclusion

It is more difficult to guarantee thorough sanitization since the plastic components of glass droppers cannot be boiled. In general, unless you're utilizing them for anything else, it is not recommended to reuse droppers.

Enjoy sterilizing your dropper bottles safely.
