This question was submitted from Robert B.
“How do I remove marks made by stainless steel teaspoons inside porcelain cups? I also have similar marks inside soup and pudding plates made by the same cutlery (18/8/stainless steel).”
The tip which I have heard of, although I have never tried it, is to use some non-gel toothpaste and rub it on the stains and rinse.
Remember to always test a small area first when using chemicals or techniques you have not used before on the surface you are cleaning.
