My daughter taught me this trick to lift dark brown coffee rings out of ceramic mugs with 0 effort. Here’s how it works

room at the top. Drop in a single denture tablet and watch as it begins to fizz and dissolve. The effervescent action will start working on the stains immediately.

Allow the solution to sit undisturbed for at least an hour. If your stains are particularly stubborn, you can let it soak overnight. Once the time has passed, simply pour out the solution and rinse your mug with cold water. You’ll find the stains have lifted away, leaving your mug looking as good as new.
