How do you sterilize used syringes?

To sterilize used syringes, first, thoroughly wash them with soap and water to remove any visible contaminants. Then, immerse the syringes in a solution of 70% isopropyl alcohol or bleach diluted with water (1 part bleach to 10 parts water) for at least 30 minutes. After soaking, rinse the syringes with sterile water to remove any residual chemicals. It's important to note that for safety and effectiveness, it's generally recommended to use new, sterile syringes rather than attempting to sterilize used ones.
