Sterilizing needles with boiling water is not as effective as using pressurized steam, and does not provide percent sterilization. It does, however, kill many microorganisms.
Boiling is not enough to kill heat-resistant bacteria, such as endospores. However, you can use alcohol to clean your skin prior to an injection. This includes both ethyl alcohol and isopropyl alcohol. Neither solution is able to kill bacterial spores, but in full-strength, high concentrations, both have antibacterial, antiviral, and antifungal properties.
Rubbing alcohol also evaporates quickly on surfaces, making it possible for bacterial growth to rapidly occur or reoccur. Sterilizing a needle in fire does not provide complete protection from bacteria and other organisms. It may be ok for splinter removal, but this method should never be used for syringe needles. Bleach is not recommended for sterilizing needles used for splinter removal, or for sterilizing medical needles and syringes.
Salt water, such as the water found in the ocean, is not sterile. Neither is water from the tap, even if you put salt into it.
To use salt water to disinfect — not sterilize — a needle for splinter removal, you must start with sterile water. Additionally, you should only use this method if a more effective sterilization technique is not available. Needles intended for medical use should be used only one time, and not reused. If you must reuse a needle, sterilization can be tried at home, but will never provide a complete, percent guarantee.
When the process time for canning a food is 10 minutes or more at , feet elevation , the jars will be sterilized DURING processing in the canner. Therefore, when process times are 10 minutes or more at this altitude, pre- sterilization of jars is not needed.
It doesn't hurt your product to do it anyway, but it does require additional time and energy and is unnecessary. To pre-sterilize jars, place the cleaned jars right-side-up on a rack in a canner and fill the jars and canner with water to 1-inch above the tops of the jars. Bring the water to a boil and then boil for 10 minutes at altitudes less than 1, feet elevation.
Add 1 additional minute for each additional 1, feet of elevation. For example, parents are encouraged to boil baby bottles and cooks are encouraged to boil canning jars prior to first use. The average time of boiling to sterilize baby bottles is 5 minutes and for canning jars is 10 minutes. There are some substances that do not withstand boiling and other methods of sterilization, such as with chemicals, are used in those cases.
In medical situations, sterilization of surfaces and tools is of utmost importance to patient health. One of the most popular methods of sterilizing is boiling. Place bottles, spoons, nipples, lids and other equipment into a pot of water and bringing it to a rolling boil for 2 minutes.
You can cover and store the equipment in a clean place. There were even a few colonies that survived 5 minutes of boiling! So, boiling does a great job sterilizing a cloth, but it is best to boil for a full 10 minutes. How long does it take for boiling water to kill germs? For added safety, the CDC recommends that you boil water for one whole minute.
