Some of us use coffee grinders. Sometimes not only to grind coffee! After a while the blades in the coffee grinders can get dull and can be difficult to sharpen. Instead of giving up and selling it at a yard sale, donating it to Goodwill or *gasp* tossing it out .... give this a try.
Sharpen the blades by running a cup of rice through it! Your blades will be sharp, the grinder saved from the landfill and fresh coffee will be brewed in no time.
Now what to do with the ground up rice?...hmmmm. Remember to give your loved ones a hug!
