Soak containers in a diluted StarSan solution
Sterilizing your lip balm containers is a great way to ensure their longevity and keep them hygienic. One way to do this is by using a diluted StarSan solution. Star San is a no-rinse, acid-based sanitizer that is trusted by homebrewers, winemakers, and other professionals. It is made with food-grade phosphoric acid, biodegradable, and septic-safe.
To make a diluted StarSan solution, you will need to mix it with water. The recommended dilution rate is 1 oz of Star San per 5 US gallons of water. This is equivalent to about 1.5 ml per litre or 29.57 ml to 18.93 litres. You can also measure it out by using a syringe to suck out 7.5 ml of Star San and adding it to your water. It is important to ensure that the water has a pH below 3, as Star San is most effective at a pH of 3.5 or lower.
Once you have prepared your diluted StarSan solution, simply soak your pre-washed lip balm containers in the solution for 2 to 3 minutes. After soaking, remove the containers without rinsing them and let them air-dry before using them again. This method is not only effective for sanitizing but can also help extend the lifespan of your containers.
It is worth noting that while Star San is generally safe for plastic, prolonged exposure to soft metals, rubber, or plastic should be minimised due to its acidity. Additionally, always refer to the manufacturer's instructions and take the necessary precautions when handling any chemicals.

Bleach solution and alcohol sanitization
Sterilizing plastic lip balm containers can be done in a few ways, including using bleach solutions and alcohol sanitization. Here is a detailed guide on these methods:
Bleach Solution:
Firstly, it is important to note that you should never mix bleach with ammonia or any other cleanser. For a bleach solution, you will need to create a mixture of bleach and water. The recommended concentration is a solution of about 5 to 10 percent bleach. This can be done by mixing one part bleach with nine parts water or a similar ratio to achieve the desired concentration. Ensure the bleach solution is properly diluted before proceeding.
Once you have your diluted bleach solution, simply soak the plastic lip balm containers in it. Bleach is an effective disinfectant and will not take long to work, so the soaking time is minimal. A rinse with tap water, followed by distilled water, will ensure any bleach residue is removed. Finally, allow the containers to air-dry completely before using them again.
Alcohol Sanitization:
For alcohol sanitization, it is recommended to use rubbing alcohol or grain alcohol. These types of alcohol are effective at killing bacteria on plastic surfaces. Always use a non-diluted alcohol solution when cleaning plastic. You can spray the alcohol inside and outside the containers, ensuring full coverage. After spraying, allow the containers to air-dry on a sanitized rack or a clean surface.
Additionally, you can soak the plastic lip balm containers in alcohol. Ensure the container is completely immersed in the alcohol for effective sanitization. Similar to the bleach method, rinsing with tap water and then distilled water is recommended to remove any alcohol residue. Allow the containers to air-dry before reuse.
Both bleach and alcohol methods are effective for sanitizing plastic lip balm containers. However, always exercise caution when handling these substances and follow proper safety guidelines.

Boiling water method
The boiling water method is a popular technique to sterilize plastic lip balm containers. It is a simple process but requires careful handling to avoid any accidents. Here is a step-by-step guide to sterilizing your plastic lip balm containers using boiling water:
Step 1: Prepare the Containers
Before boiling, it is essential to remove any remaining product from the containers. Use a Q-tip or a piece of cloth to clean out the inside of the containers. If there is stubborn residue, you can fill the container with rubbing alcohol and let it sit for a few hours to loosen the gunk. Make sure to do this over a sink, as you do not want to pour oils down the drain.
Step 2: Boil the Water
Fill a pot with water and place it on the stove. Choose a pot that is large enough to submerge the containers completely. Turn the stove burner on high and wait for the water to reach a rolling boil. Covering the pot with a lid can help speed up the process.
Step 3: Submerge the Containers
Once the water is boiling, it is time to add the containers. Use tongs or a spoon to gently lower the containers into the water. Be very careful, as the steam and hot water can cause burns. Ensure that the containers are fully submerged and not floating.
Step 4: Boil for 5 Minutes
Let the containers boil in the water for approximately 5 minutes. Keep an eye on the pot to ensure the water continues to boil and does not overflow. If necessary, adjust the stove temperature to maintain a steady boil.
Step 5: Remove and Dry
After 5 minutes, use tongs to carefully remove the containers from the boiling water. Place them on a clean towel or drying rack. The containers will be extremely hot, so handle them with caution. Allow them to air dry completely before reusing them.
Additional Tips:
- If you are sterilizing multiple containers, you may need to boil them in batches to ensure they are all fully submerged.
- Always exercise caution when working with boiling water to avoid scalding.
- Make sure the containers are completely dry before filling them with new products.
The boiling water method is an effective way to sterilize plastic lip balm containers, ensuring they are clean and safe for your next use.

Using a Q-tip to clean
To sterilise plastic lip balm containers, it is recommended to clean them thoroughly, especially if they have been used on a person's lips. Firstly, empty out the containers as much as possible using a spoon or a similar tool. You can also use a small hard object to scoop out the remaining product from the base of the container.
Then, remove the little platform that moves the product up and down, also known as the stopper or the "thingy". Clean the stopper separately by boiling it in water and using a Q-tip to wipe away any remaining product.
To clean the inside of the lip balm container, pull off the top of a Q-tip and run it around the inside of the tube. Q-tips are particularly useful for reaching narrow spaces that rags or paper towels cannot access. After cleaning the inside with the Q-tip, roll the stopper back down and swipe the inside again with the other side of the Q-tip. Repeat this process if there is still product residue in the container.
Finally, to sterilise the containers, place them in a pot of boiling water for about 3 to 5 minutes. This will ensure that they are completely sterilised and ready for reuse. It is important to note that some sources suggest not pouring balm at temperatures higher than 120°F to avoid expanding the parts inside the tube.

Hand wash and dishwasher
To sterilize plastic lip balm containers by hand, start by removing any labels and taking off the lids. Next, fill a pot with water and bring it to a boil. Carefully place the containers in the boiling water for 3-4 minutes using tongs. Then, remove the containers from the pot and wipe them off with a rag or paper towel, making sure to get into all the crevices.
Alternatively, you can use a mild detergent or antibacterial dish soap and hot water to wash the containers. Combine this method with another sterilization technique for best results. For example, after washing the containers, you can soak them in a bleach-water solution of about 5 to 10 percent bleach. Bleach will quickly disinfect, so soaking time will be minimal.
You can also use a degreaser, such as Sam's kitchen degreaser, and a small brush, such as a baby bottle nipple brush, to scrub out the tubes. After scrubbing, allow the containers to air-dry completely, which may take a couple of days in high humidity.
To sterilize plastic lip balm containers in the dishwasher, place the containers in the top rack of the dishwasher, with the lids in the silverware holder. It is recommended to run the dishwasher without heavily soiled dishes. While the dishwasher will clean the containers, it will not sanitize them. Therefore, you may want to combine this method with another sterilization technique, such as using isopropyl alcohol or a bleach solution.
