I am trying to figure out what is best for me to sterilise my cup. I was thinking about buying a silicon cup to fill with previously boiled water (because I don’t have a microwave) and then leave the cup inside for like 5 min. My question is: is leaving the cup in hot water for 5 minutes as effective as boiling it in water for like 3 minutes? Thank you.
