Tea and coffee stains can happen to any mug, but the good news is they are able to be cleaned and returned to an as new condition.
If your Ecology homewares are stained, here is a simple remedy that can do the trick:
-Wet the inside of the mug with cold or lukewarm water, and sprinkle in a thin layer of baking soda, (enough so it covers all brown marks) it should stick easily to the damp sides of the cup.
- Leave for a few minutes, and then use a cloth or sponge to wipe all around the brown ring.
You can also try with white vinegar or lemonade.
Another remedy is to fill the cup with a mixture of salt and water, let it soak, then clean gently to remove the marks
