Water Jug

Anyone know a way to sanitize a 4 gallon water jug? Filtered, the kind you buy at the store 2 refill.?
People mostly use these for water fountains. They are so big. I thought vinegar would be good, but it would take so much and wouldn’t get around enough to sanitize it. Uhhh.
Use a little bleach and water and thin rinse it well with boiling hot water. That should get it clean.
