All sorts of rice, but I only really use rice that comes in large 25 lb bags. I wash rice using cold water, replacing the water at least times. Usually when you add water and some agitation, the water appears off color and somewhat white. It makes you think what's in there considering it should take more than that just to breakdown starch. Maybe it's bleaching agents or other stuff. But considering that it's just for show, it shouldn't really be eaten.
