33. Deodorize your coffee grinder
When using coffee grinders or fully automated coffee machines there is often an unpleasant smell coming from the grinding mechanism. The reason for that is a build-up of bacteria and other germs. Coffee contains oily compounds that serve as a great breeding ground for germs. Salt helps you to deal with that. Simply use around half a cup of salt and mix it with some water and let it run through the grinding mechanism. Make sure this is safe in case of using a coffee machine first. Regular, manual coffee grinders will be unharmed by the saltwater treatment.
You can also use salt for the other elements of the coffee machine like the waste removal box for example.
