How we can sterilize cotton and needle?

There are several methods to sterilize needles, including boiling water, steam, and flame sterilization. For example, you can sterilize a needle by boiling it in water for at least 30 minutes. Another method is to use steam, which is one of the most widely used and effective methods for sterilizing needles. No living thing can survive direct exposure to saturated steam at 250 degrees Fahrenheit (120 degrees Celsius) for longer than 15 minutes.

Cotton can be sterilized using an autoclave or by using gamma irradiation. These methods are typically used in medical or industrial settings.
