How to Clean Antique Stoneware

Stoneware is made from clay fired at high temperatures. Stoneware is durable and withstands a wide range of temperatures, making it an ideal material for cookware. Antique stoneware is a valuable asset to any collector, but it requires care to prevent damage. Since stoneware is a porous material, soaking it in water or using harsh detergents can cause staining and an uneven appearance. Treat antique stoneware gently and only wash it as needed to keep it in top condition.

Things You'll Need

• Mild liquid dish-washing detergent
• Bucket
• Soft cloths
• Cotton balls
• Distilled water

Instructions

1. Add 1 or 2 tablespoons of mild dish-washing liquid detergent and 1 gallon of warm water in a bucket.

2. Dip a soft cloth into the cleaning solution and wring it out.

3. Wipe the stoneware with the cloth to remove any residue or dirt. For small spots, use a cotton ball dipped in the cleaning solution. Rinse the cloth in the cleaning solution as needed. Don't saturate the stoneware with water.

4. Dampen a cloth or cotton balls with clean distilled water and wipe the stoneware to remove any cleaning residue.

5. Air dry the stoneware in a well-ventilated area.

Tips & Warnings

• Handle stoneware carefully to prevent breakage.

• When storing antique stoneware, wrap each piece in acid-free tissue and place it in a sturdy box.
