You can clean it by hand-washing with liquid dish soap and rinsing thoroughly. (You don't want soap residue left in the bowl to add to your next salad.) I've had mine for about 10 years and usually only rinse it well and leave to dry, sometimes running water inside the lid and letting the cord hang out until it's also dry. It's very important that it dry completely to prevent mold or other stinky conditions developing, but that's never a problem if you let it dry well. Best just to leave it in the dish rack or on a towel on the counter. Occasionally I've run it through the dishwasher on the top rack but not with the dry cycle for fear it would be damaged/softened. I love mine and have found it durable and very effective.
You can't fix it. You need to buy a new lid (part number 15000L for the 10 in lid).
