agreed. I soak in oxiclean after I get a batch that I've used previously. Rinse 3-4 times and then store them. Then right before I use them, I pull them out...rinse them again and run them through the sanitize cycle in the dishwasher. As soon as they are done, I rinse them with star san and put them back into the dishwasher to drain before filling them. Probably a bit OCD, but it's worked for me.
