Electric Coffee Grinder

How do you clean a spice/coffee grinder?

I have this electric spice grinder and i want to grind sesame seeds in it. I have used it for coffee beans before. So, how do I clean it properly so that i am not mixing sesame seeds with coffee beans?

Tear up a piece of bread and run it in the grinder. It’s like a sponge and will clean things up nicely. I use it all the time.
