When was the last time you cleaned your coffee grinder? It's easy to forget that your coffee grinder needs a cleaning, but luckily it's easier than you think. All you need is a cup of oatmeal.

Coffee is an organic material filled with oils that over time will form layers of residue on knives and containers. So a little cleaning every now and then is a good idea, and it's not as difficult as you might think.

If you want to clean more thoroughly, you can use a brush to remove residue from the blades and the coffee container can be washed with water. An even more thorough wash will require a suitable cleaning agent for grinders.

After you've finished cleaning, take a well-deserved coffee break!
