Are you still staring at a stubborn stain? Time to get weird. Grab a denture cleaning tablet from the pharmacy.
Drop it into your mug with warm water. Watch it fizz like a science fair volcano. Let it sit for 20 minutes.
Denture tablets are designed to remove tough stains from teeth. Your tea cup? It has teeth too, apparently. Rinse well, and your mug will look brand new.
You’ll also feel a little bit like a mad scientist. That’s a bonus.

Your mug will smell like a lemonade stand. That’s a win-win.
