My DH thought of a great way to really clean out the junk inside those straws! He takes a bamboo skewer (you know those long thin sticks you might use for BBQ skewers) and then rolls up a thick wad of paper towel. Then he pushes the paper towel through using the bamboo skewer (because it's thin enough and strong enough to push the paper towel through the straw). As the paper towel goes through the straw, it drags along all the crud the sticks to the sides of the straw with it. You can do this a couple of times until the paper towel comes out clean and then throw it into the dishwasher for good measure! This works like a charm for all our straws!
