Sparksals, I'll definitely check out that link, because I tend to add water instead of dumping and starting with fresh. I clean it out 1x/week.
Yeah I picked up this 7 qt. stainless steel kettle at an Amish store in the area. I don't know if they just needed a kettle because they'll have anywhere from 8-18 kids or if it serves double use to put on a wood-burner to put moisture in the house. It just comes in handy for us because I put a small amount of water in it to boil for coffee, but when I'm entertaining, I keep it full and simmering for when my girlfriends want their hot tea!
