Question

How do you clean coffee stained porcelain cups?

Answer 1

Several ways, obviously a dishwasher, but if you are doing them by hand you can soak them in hot dishwasher powder suds, hot biological washing powder suds, bicarbonate of soda in hot water or denture cleaner.

Answer 2

Don't bleach, you will knacker the porcelain protection. Bicarbonate of soda will oxodise and lift the stains away, or reansomly coca cola so ssooo acidic if you live a penny in it over night it will be shining by the morning, so if in doubt, cola them!

Answer 3

Denture cleaner.

Answer 4

DON'T LET THE COFFEE SIT IN THE CUPS.   When you are done using them, either wash them immediately or fill them with water.
