A grater is a very useful instrument in the kitchen and I think it's fun to use it. You can use it for a lot of food: cheese, citrus fruit peel, nutmeg, all kinds of vegetables etc.

The thing that bothers me about it is how to clean it easily. I've tried a couple of methods but they are labour-intensive or they ask a great deal of time.

Anyone here knows an easy yet good way to clean them?
