Contamination and sterilization

Basically i’m down to my last pipette and i need to use it tomorrow as a new order won’t be in until Monday.
However, i’m sure i’m used this pipette before as it has been marked. If my memory serves me well, i’ve used this one to transfer IH into a togo bottle. That was about 2 weeks ago.
Now i need to transfer some Ammo in a togo bottle with this one and i don’t want to cross-contaminate my stock.
Would boiling the pipette in water mixed with Alcohol or Witch Hazel sterilize the pipette?
Same question goes to empty togo bottles? :roll_eyes:

Just use some peroxide and skip boiling
