Want to avoid this whole mess in the future? Rinse your mug immediately after drinking. I know, I know—you’re busy.
But that 30-second rinse saves you ten minutes of scrubbing later. Run hot water over the inside and wipe it with your finger. Boom, gone.
Also, don’t let your tea sit for hours and hours. That’s like inviting the stains to a party.
If you’re a chronic tea-stainer (like me), consider using a cup with a glazed interior. Rough ceramic holds more stains. Smooth surfaces? They laugh at tannins.
