Use denture tablets to clean your coffee maker
Hard water leaves mineral deposits in the tank of your electric drip coffee maker that not only slows the perking but also affects the taste of your brew. Denture tablets will fizz away these deposits and give the tank a bacterial clean-out too. The tablets were designed to clean and disinfect dentures, and they’ll do the same job on your coffee maker. Drop two denture tablets in the tank and fill it with water. Run the coffee maker. Discard that potful of water and follow up with one or two rinse cycles with clean water.
