3 Ways to Sterilize and Disinfect Medical Instruments


Sterile medical equipment is a must-have in any situation to prevent infection. Some instruments are reusable, but they need to be properly disinfected before being used again. Here are a few options you have to correctly sterilize your equipment.


You can soak your equipment in a 0.1% bleach solution for 15-30 minutes to disinfect and sterilize it. However, any longer than the suggested 30 minutes may result in the equipment rusting, rendering it useless.

Boil Method

This method may not kill some bacteria, but it’ll work in a pinch. Simply place the instruments in gently boiling water for 30 minutes. Using this method repeatedly may result in the instruments rusting, especially knives and scissors, which should always be open during sterilization.

You can use basic 70% isopropyl alcohol available at just about any store to sterilize instruments as well. Simply let the tools soak in the alcohol for 30 minutes. Some people choose to ignite the alcohol as well, but it’s not necessary.

To use these methods properly, you need to be able to rinse the tools with sterilized water. Check out how you can disinfect water with a common household product.
