My name is Rachel Yatuzis, and I'm going to show you how to clean a plastic water container with baking soda. It's fairly simple. You want to add just a little bit of baking soda, maybe that much to your container. (I'll use this.) Pour just a little bit of water in there. You can mix it up with your hand to make, it's like a gritty liquid. Liquidy-type substance. And you just work it around with a sponge. Baking soda works wonderful on cleaning almost anything. If there's stains, the baking soda will get it out. And then, you just rinse it out. Dry it. And it is clean.
