Using your Rig-Tig Parmesan Mill is a breeze. First, open the mill and fill it with blocks of parmesan cheese. Then, close it up and hold the mill over your pasta or whatever you're adding cheese to. Twist the top of the mill, and fresh parmesan will come out. You can twist it as many times as you need to get the right amount of cheese. When you're done using it, you can store the mill in the fridge with the cheese still inside to keep it fresh. Just make sure to clean the mill regularly. You can wash it with warm, soapy water and a soft sponge. Avoid using abrasive cleaners as they can damage the plastic and steel parts. And remember, this item has a 30 - day return policy if you're not satisfied.
