One user said: “Bicarbonate of soda. Put a little in the cup, get a damp cloth, and rub the stain with bicarbonate of soda, using the cloth.
“Takes a bit of elbow grease but does the job, once stain gone just wash and rinse the cup in warm water.”
Another user said: “Bicarbonate of soda and boiling water…works on spoons etc too!”
However, some users suggested that how you make your tea could lessen the likelihood of stains developing.
