I just soak in oxyclean for a day or two then triple rinse them then sanitize. I know its kind of wasteful but it works great and I'm not exactly in an area where fresh water is in short supply. I suppose if you wanted to conserve water you could do a couple rinse buckets. The first would be like a dirty rinse then the second bucket could be a clean rinse.
