Can Porcelain Go in the Dishwasher?
Generally, yes, most porcelain can be safely washed in a dishwasher. However, certain types, especially those with delicate metallic accents or antique designs, require handwashing to prevent damage.
Understanding Porcelain: A Durable Elegance
Porcelain, prized for its delicate beauty and surprising durability, has graced tables and homes for centuries. Understanding its composition and manufacturing process is key to knowing how to care for it properly, including whether it can withstand the rigors of a dishwasher cycle.
Porcelain is a type of ceramic made by heating fine clay at extremely high temperatures. This process results in a dense, non-porous material renowned for its strength, translucence, and resistance to chipping and scratching. While inherently durable, porcelain’s susceptibility to dishwasher damage depends largely on its glazing, decoration, and overall construction.
The Dishwasher Dilemma: Factors Affecting Porcelain’s Safety
Several factors determine whether your porcelain can safely withstand the heat, detergents, and forceful water jets of a dishwasher. These include:
- Glaze Quality: A well-fired, high-quality glaze provides a protective barrier against chemical etching and abrasion. Inferior glazes are more prone to clouding or scratching.
- Decoration: Porcelain with hand-painted designs, metallic accents (gold or silver trim), or intricate patterns is more vulnerable to damage. The heat and harsh chemicals can fade, chip, or even dissolve these delicate embellishments.
- Age and Condition: Antique or heirloom porcelain, regardless of its original quality, may have weakened over time. Cracks, crazing (fine lines in the glaze), and existing damage make it more susceptible to further deterioration in the dishwasher.
- Manufacturer’s Recommendations: Always check the manufacturer’s instructions or markings on the porcelain itself. Many modern porcelain sets are explicitly labeled as dishwasher-safe. When in doubt, err on the side of caution and handwash.
Best Practices for Dishwashing Porcelain
If you determine that your porcelain is dishwasher-safe, following these guidelines can minimize the risk of damage:
- Load Carefully: Space items apart to prevent them from knocking against each other during the wash cycle. Avoid overcrowding the dishwasher.
- Use a Gentle Cycle: Opt for a delicate or china cycle with lower temperatures and water pressure.
- Mild Detergent: Choose a phosphate-free, mild detergent specifically designed for fine china and glassware. Avoid abrasive cleaners.
- Top Rack Placement: Place porcelain on the top rack, away from the heating element and direct spray.
- Avoid High Heat Drying: Disable the heated drying cycle, as high temperatures can accelerate fading or damage.
Common Mistakes to Avoid
- Washing porcelain with metal utensils: The metal can scratch the porcelain surface.
- Using abrasive cleaners or scouring pads: These can damage the glaze.
- Overloading the dishwasher: This increases the risk of items colliding and breaking.
- Ignoring manufacturer’s instructions: Always refer to the manufacturer’s guidelines for specific care recommendations.
- Assuming all porcelain is the same: Not all porcelain is created equal; consider the age, decoration, and quality of your pieces.
Recognizing and Preventing Damage
Look for signs of damage such as fading, scratching, chipping, or clouding of the glaze. These indicate that the porcelain is not withstanding the dishwasher’s conditions. Prevention is always better than cure, so handwashing remains the safest option for delicate or valuable pieces.

| Porcelain with Gold/Silver | Usually No | Metallic trim is highly susceptible to damage; always handwash. |
| Antique Porcelain | No | Best to handwash due to potential weakness and delicate construction. |
| Hand-Painted Porcelain | Usually No | Hand-painted designs can fade or chip; avoid dishwasher. |
Frequently Asked Questions (FAQs)
Is it safe to put my grandmother’s antique porcelain tea set in the dishwasher?
No, it is strongly recommended to handwash antique porcelain tea sets. These delicate heirlooms are often fragile and may have intricate details or metallic accents that are easily damaged by the heat and harsh chemicals in a dishwasher.
What is the best type of detergent to use if I decide to put porcelain in the dishwasher?
Choose a phosphate-free, mild detergent specifically formulated for fine china and glassware. Avoid detergents that contain bleach, citrus additives, or abrasive agents, as these can etch or dull the glaze on your porcelain.
Will the dishwasher fade the colors on my porcelain plates?
Yes, repeated dishwasher cycles can cause colors to fade over time, especially on porcelain with delicate decals or hand-painted designs. Using a gentle cycle and avoiding high heat drying can help minimize fading.
Can the dishwasher scratch my porcelain?
Yes, abrasive cleaners, rough handling, and contact with other items in the dishwasher can scratch porcelain. Load the dishwasher carefully, use a mild detergent, and avoid overcrowding to reduce the risk of scratches.
My porcelain has crazing (fine cracks in the glaze). Is it still safe to put it in the dishwasher?
No, porcelain with crazing is more vulnerable to damage in the dishwasher. The heat and water pressure can exacerbate the cracks and weaken the overall structure. Handwashing is the safer option.
What does “dishwasher safe” actually mean for porcelain?
“Dishwasher safe” generally means that the porcelain has been tested and found to withstand a certain number of dishwasher cycles without significant damage. However, it doesn’t guarantee that the porcelain will remain in perfect condition indefinitely. Always use caution and follow best practices to prolong the lifespan of your porcelain.
Is it okay to use the high-heat drying setting on my dishwasher if my porcelain is labeled dishwasher safe?
Even if your porcelain is dishwasher safe, it’s generally best to avoid using the high-heat drying setting. High temperatures can accelerate fading, chipping, and other types of damage. Instead, allow the porcelain to air dry or gently towel dry it.
My porcelain plate has a small chip. Can I still wash it in the dishwasher?
A chipped porcelain plate is more likely to break further in the dishwasher. The heat and water pressure can weaken the damaged area. It’s best to handwash chipped porcelain to prevent further deterioration.
How do I know if my porcelain has metallic accents?
Metallic accents, such as gold or silver trim, are typically shiny and reflective. They may appear as thin bands around the edges of the porcelain or as intricate details within the design. If you’re unsure, err on the side of caution and handwash.
Can I put my porcelain cups in the dishwasher upside down?
Yes, it’s generally recommended to place porcelain cups upside down in the dishwasher to ensure proper cleaning and drainage. However, make sure they are securely positioned to prevent them from moving or falling during the wash cycle.
What if my dishwasher uses hard water? Will that affect my porcelain?
Hard water can leave mineral deposits on porcelain, causing it to look cloudy or dull. Consider using a dishwasher rinse aid to help prevent mineral buildup. A water softener can also improve the overall water quality and protect your porcelain.
Is it better to handwash all porcelain, regardless of whether it’s labeled dishwasher safe?
Handwashing is always the safest option for preserving the beauty and longevity of porcelain, especially delicate or valuable pieces. While many modern porcelain sets are dishwasher safe, handwashing provides greater control and minimizes the risk of damage.
