Now tea sets are all coffee flavour, with coffee grounds
With two teaspoons of salt, and then, with warm water and warm water into a cup of coffee just about. Bubble on the night, the next day, throw away the water in the cup, then take a little edible address, brush touch inside the cup, only need a minute, no taste but also no coffee cup:)
Use white vinegar soak first half an hour later, scrub with toothpaste can if brightness is new.
If there is no time just after drinking coffee, cup, also can be directly use salt dry cleaning, I haven't taste the hedge
