How to clean out a tank that's been outside for a few months?

[Jrf456]

I have a 3g Kritter Keeper in the closed in back porch that has been out there for 3 months with rocks in it. It's under a roof and sitting on a shelf out there. I'm obviously not gonna use the rocks, but would it be safe to use the tank? If so, how do I clean it to make it safe? Thanks! :)

Rinse thoroughly and soak with HOT water.

No soap and some people use vingear and water to wash it with and rinse rinse rinse and maybe let it sit out in the sun to dry and rinse some more.

Hot water and vinegar. Rinse and keep rinsing until it doesnt smell like vinegar anymore. Let dry outside. Reuse.
