Well, the issue is that sometimes I can't get to a grocery store because I don't have a car. (Disney provides free transportation from MCO to their resorts, so I don't need a car if I stay at a Disney resort) I'd like to have the bleach on hand to run through the jacuzzi before using it (Disney cleans things well, but jacuzzis can have bacteria growing in their piping.) You make a good point, though, about how bleach tends to get out of bottles, which could ruin the other stored items. I think I'll look into bringing a powdered disinfectant with me.
