Answer:
Boiling water and alcohol
Step-by-step explanation:
Nowadays we know that we can never disinfect completely a syringe, so that is why we don't do it and we use a new one every time.
Although the best way to disinfect a syringe may be the following method:
- Disinfect the syringe using sterile cotton balls soaked in 70% alcohol. Rub all the surface of the syringe with the cotton until you feel that the alcohol covered everything. This will kill most bacteria but not everything.
- Sterilize the syringe using an autoclave machine. An autoclave machine is nothing but a special pressure pot that uses steam pressure and heat to kill most of the organisms, except spores and heat-resistant bacteria.
- Just to help more the probabilities of killing the most part of microorganisms, repeat the step number one. Use alcohol after taking out the syringe from the autoclave.
- Use the syringe right away or it will get infected again in a matter of seconds.
