Things You'll Need
Liquid dish soap
Antique Wedgewood or, as some spell it, Wedgwood Jasperware is best cleaned by hand. If you try to clean your Wedgewood in the dishwasher, the excess heat may damage it. Likewise, using abrasive cleaners or extremely harsh chemical cleaners, like muriatic acid, may damage or even ruin your Wedgewood. If you absolutely have to use a scouring agent on the Wedgewood to remove soil, use baking soda as a scouring powder.
Mix liquid dish soap with warm water. Dig a rag in this and wipe the Wedgewood clean.

Dip an old toothbrush in the soap mixture and use it to scrub at any stubborn soil on the Wedgewood.
Soak the Wedgewood in the dish soap mixture, if necessary, to remove soil that won't scrub right off. Before you do this check to make sure there are no chips all the way through the finish on the Wedgewood. If there are, you'd be better off not soaking it.
Rinse the Wedgewood clean of all soap in running water, then wipe dry with a soft, dry cloth.
