Cleaning Coffee Cup Stains

You are drinking your coffee and you notice that the cup is ringed with stains. When you are done drinking it grab an orange/lemon rind and some salt. Drop a pinch of salt into the mug and using the rind like a rag, wipe out the inside of the mug gently scrubbing away the stain. Now toss the rind in your garbage disposer and grind for a minute without running water. Wash your mug as normal. Now you have a sparkling clean mug and a fresh smelling kitchen!
