I have good success with about a cup of white vinegar to a full tank of water. Remove top and plug in, outdoors, unless you want your house to smell like a pickle. Check on it periodically, and after about an hour, things should be dissolved. Brush away the mineral deposits and rinse carefully.
Be well,

Someone once posted a formula for cleaning water distillers. I haven't been able to find it and would appreciate anyone who could pass it along.
Thanks.
