Whether you’ve been lucky enough to inherit a yellowed group of fine china or you just want to eliminate the discoloration on your daily dishes, soaking in a whitening solution is key. Over time, spices and oils can leave stains on dishes, and knives and forks can leave gray marks, demanding a deeper cleaning than the usual trip through the fridge along with a soak in the sink. But even antique dinnerware can be returned to its former glory with sufficient patience and time.
Baking Soda Method
Fill a sink with hot water and mild dishwashing liquid. Add 1 cup of white vinegar.
Put the dinnerware in the sink and let it soak for 10 minutes.
Wash each piece with a soft sponge or cloth. Lay the wet dishes on a towel with the stains facing up.
Pour 2 tablespoons of baking soda into a bowl and add enough water to make a thick paste. Stir the solution with a soft toothbrush.
Scrub the stains with the toothbrush to eliminate them. Leave the paste on for a couple minutes before rinsing if the stain is particularly tough.
Wash the plates with hot water and air dry them on a dish rack.
Hydrogen Peroxide Method
Put the stained dinnerware in a container large enough that it can be totally submerged in it.
Fill the container with sufficient hydrogen peroxide to cover the merchandise and place the lid on the container.
Catch the item in the container to soak. Check it each day to see if the stain is gone, then adding additional peroxide if necessary. It may take two to four weeks to see whitening of quite stained items.
Wash the item with hot water and dishwashing liquid. Allow it to dry on a dish rack.
