How can I filter out unwanted particles in my chicken broth? I often like to cook an entire chicken in water in a crockpot. After the chicken is done cooking, I remove all the meat and then throw the bones &amp; organs back in, pour some extra water in, and let it sit for a day on "Keep Warm".

Now the only thing is that I find that there's some brown particles floating around that I'd rather not be in there. I do my best to clean out the chicken before putting it in, but I'm still not entirely trusting.

Anyway, how can I filter this stuff out to just leave me with a liquid broth?
A piece of muslin/cotton/fine-tissue-of-your-choice will do the job nicely.

You can easily find it in kitchen stores or online.
