Is it common knowledge that leaving a tea bag in a cup can cause staining?

Did we also know that if we leave that cup to dry out it becomes tough to remove without soaking or bleach?

I'm not trying to be patronising this is an actual question.

No, I did NOT know that! But some of my clear glass coffee mugs have coffee stains right where the person drinking might sip. The only way to remove the stains is with an abrasive, and that means that area will ALWAYS catch stains afterward.

@4meAndyou soak and bleach. Try that instead
