As most of my pieces are unglazed porcelain, they can tend to get a little marked over time.
The best way to clean your porcelain pieces is with a little bit of cream cleanser, such as Jiff.
If your piece has embossing or impressions, you can get into the nooks with an old toothbrush.
Just clean with a little bit of Jiff and rinse under water.
It's as easy as that......
