Cleaning cosmetic glass dropper bottles properly is key to keeping your serums, essential oils, and liquids free from contamination. Follow this quick 4-step process to ensure they’re spotless and safe for reuse.
First, disassemble the glass dropper bottle—separate the rubber bulb, glass pipette, and bottle itself. Fill a bowl with warm (not hot) water and let all parts soak for 10–15 minutes. This loosens residue, oils, or dried liquids clinging to the surfaces, making them easier to clean.
Next, disinfect with rubbing alcohol (70% isopropyl works best). Either submerge all components in alcohol for 5 minutes, or pour alcohol into the bottle and squeeze the bulb repeatedly to flush the tube thoroughly. Alcohol effectively kills bacteria and breaks down tough, stubborn grime that plain water would likely leave behind.
After alcohol treatment, rinse all components with warm water to remove any alcohol residue. Then, air-dry them completely on a clean towel—laying them upside down helps speed up drying and prevents moisture buildup, which can lead to mold.
For an extra layer of sanitization, use an infrared ozone sterilizer. Place the dry parts inside, run the machine according to its instructions (usually 10–20 minutes), and let it complete the cycle. Ozone and infrared light work together to eliminate even the tiniest pathogens, ensuring your dropper bottles are germ-free and ready for their next use.
This straightforward routine keeps your dropper bottles in top shape, protecting your products and extending the life of your containers.
