Hey I have recently been trying to get my teeth looking better and my shoes and I have found the thing that works and it is cheap and can be bought at almost any food store. Well I have been hearing that Baking Soda will clean teeth and well I tried it and man it has a very bad taste but it works so good. It will make your teeth from yellow to white if you use it frequently. And it works for shoes and food making to. Well I had used it for my shoes to and all you have to do is take a tooth brush, water, and Baking Soda. Well I have been putting it on my shoes to clean them and it works great. So there are so many things you can do with Baking Soda. It goes from making food, cleaning shoes, brushing teeth, and even more. So if you need white teeth and don't want to spend alot of money then you can use this. And what is even cooler is that you can have fun with it to because you can take Baking Soda and Vinegar and make a fountain out of it. So I hope that my review help you in any way.
