How do i sanitize play sand from a hardware store? I've been told its ok to do this but i don't know how to do it safely and properly. I'm also wonder if theres a way to make sure there's no harmful chemicals in the sand and if there is how do i eliminate the harmful chemicals?

If would be awesome if some one could give me some answers, after all i'm really new at this and could use a few pointers. I've done lots of research but i think its also a good idea to ask people who have them as pets themselves. Right now i only have gravel and it really doesn't seem to hold enough heat or moisture. my poor little guys need a better substrate
