Fishy vaginal smell

My vagina smells fishy, I have been using Vagisil PH Balance on it which I know is bad for me and I stopped using it today. I watched a gynecologist's video online saying you can wash your vulva with Cetaphil face wash because its very mild so I started doing that today instead.

However I dont want to keep irritating it so Should I just wash it with hot water until the smell goes away completely? I am not sexually active right now so it's not a super big deal but it does still bother me.
