Tea rapidly stains white porcelain, but plain water, a scouring pad
and elbow grease will remove them. If you have a lot of stained China,
then the fastest way of removing the stains is by soaking it in
bleach.  Not all porcelain will stand up to this treatment: in
particular, painted or gilt porcelain must be overglazed or else the
bleach may damage or discolour the paint.  On the other hand, I would
argue that painted, unglazed porcelain is suitable only for decoration
and not for daily use, because the heavy metals used in the
manufacture of many porcelain paints will leach out and poison you. If
unglazed porcelain is stained, then a scouring pad will also damage
the paint just as badly (if not worse) then bleach would.

Never bleach unglazed clay or pottery, because the bleach will soak
into the clay and each time you use it, your tea will hence forth
acquire the penetrating aroma of bleach.

  • Another way to clean tea stains from a vessel is to put one of those dishwasher pods in it overnight soaking in water.  It’s an easy way to clean everything up though it might seem like a lot of soap for just one little cup.  By the way, I just love the new look of this blog.  It’s one of the best-looking designs of any tea blog now.  And I follow almost 200 of them.

    • hi, in China, we dont use the bleach to wash away the stains in the porcelain cups or vessels. Instead, we use the venigar to wash them and have a very good effect.

      Probably you can try this way and see the effect.

      Very good article.

      • I have to agree about cups not standing bleach.
        My wife has been far too fond of using it and as a result we have in the last 22 years replaced several sets of china as a result.
        Soap powder soaking is just as bad and I suspect the dish-washer tablets will eventually go the same way as I have often heard of glass going dull due to continued dish-washing in a machine.
        So good old fashioned sponge and elbow grease is for me the main solution.
        However there are additional steps that can be taken to help.
        The use of low tannin teas from my supplier of fifteen years The Tea and Coffee Emporium, has helped, along with the addition of a slice of lemon in the cup and the consumption of green teas, not to mention filtering water to remove some of the hardness.
        The ultimate solution of course is abstention, but life without tea?
        Ugh … not worth thinking about.
