Don’t let brown tannin stains ruin a perfectly good cup of tea. Here’s how to remove tea and coffee stains from cups and mugs naturally.
Years ago I had a colleague who was prone to black tea in a very particular cup. However, he never washed the cup. Instead, he just rinsed it with water each time.
I would always shudder when it was my turn to make tea for everyone. The cup was so badly stained with tannins from the tea, that the white cup was completely dark brown on the inside – almost like a coating of fur. It was SO disgusting.
Whilst my colleague claimed the tannins in the mug contributed to the perfect cup of tea, I completely disagreed! I’m definitely of the mindset that to make the optimum cup of tea you need to start with a clean cup or mug.
Whenever I made the tea I’d sneakily scrub out his cup with hot soapy water to make it a little more hygienic to handle. Yet even hot soapy water and a scourer were never enough to touch the sides. Those brown tannin stains seemed to be an integral part of that cup.
I am partial to a cup of tea – particularly plastic-free tea. And I’ve found that no matter how well – and how often – you wash your cups and mugs, they do often develop these tannin stains.
Thankfully, over the years I’ve found the best ways to remove tea stains from cups, cheaply, naturally and easily in just 30 minutes.
How To Remove Tea and Coffee Stains From Cups & Mugs
To remove stains from tea cups and coffee mugs, all you need is some soda crystals – also known as washing soda.
Simply add one teaspoon of soda crystals to the cup, and then fill the cup or mug with boiled water straight from the kettle.
Stir to dissolve the soda crystals, and leave the solution to soak in the cup for at least half an hour.
After half an hour, pour out the solution, and wash the cup in your sink using warm water and a little washing-up liquid, using a scourer or scrubbing brush to remove any residue.
For particularly stubborn stains, try soaking your cups overnight. Then scrub and wash them as before to shift these stains.
It’s such a simple and non-toxic way to remove stains, that I don’t recommend any other method. Nothing else I’ve found is as effective as soda crystals.

What Are Soda Crystals Exactly?
If you are wondering what soda crystals then, soda crystals are a simple one-ingredient product – sodium carbonate. In plain English, this is a salt that contains no other additives.
Soda crystals are used in the soap, textile, and glass industries, and are made by combining salt water with limestone. The resulting chemical reaction causes soda crystals to form – producing a simple and non-toxic yet effective cleaning agent.
If you don’t want to buy a bag of soda crystals just to clean your tea cups, then worry not. Soda crystals have heaps of uses around the home. From naturally unblocking drains to cleaning your washing machine and much more. In fact, here are 15 uses for soda crystals. I am never without a bag!
I’m a huge fan of natural cleaning methods like this simple method of cleaning tea cups. I hope that by demonstrating just how effective natural products can be at cleaning, you might be convinced to give products such as soda crystals and bicarbonate of soda a go at cleaning the rest of your home.
