Denby Pans: Dishwasher-Safe?

Modern Denby stoneware is generally dishwasher-safe, but there are some exceptions and precautions to be aware of. While most everyday dishes can be safely washed in the dishwasher, certain items like wood, specific types of pots and pans, crystal, china, and knives can be damaged by the high heat and detergent. Denby stoneware from about 1950 onwards is usually safe to put in the dishwasher, but there is a risk of dulling of the glaze, especially in hard water areas. To minimise this risk, it is recommended to use liquid dishwasher detergent rather than powders or tablets, always use rinse aid, and wash at lower temperatures. Antique Denby or anything pre-1950s should not be put in the dishwasher as it could cause crazing or damage.

Are Denby Pans Dishwasher Safe?

Denby stoneware is dishwasher-safe, but may become dull

Denby stoneware is generally dishwasher-safe, but there are a few things to keep in mind to avoid damage and dulling. While Denby stoneware is known for its durability and chip resistance, the glaze on some pieces may become dull over time if washed in the dishwasher, especially if you live in an area with hard water. To minimise the risk of dulling, it is recommended to use liquid dishwasher detergent rather than powder or tablets, as the latter can be abrasive before they dissolve completely. Additionally, always use a rinse aid to prevent mineral deposits from forming on your Denby items during the final hot rinsing stage. If you live in an area with hard water, using a water softening product is also advised.

When washing Denby stoneware in the dishwasher, it is important to stack items securely to prevent them from clattering against each other and potentially causing damage. Avoid placing Denby items in direct contact with metal objects such as cutlery and pans, as this can cause damage and metal marks. Antique Denby and pieces made before the 1950s should not be placed in the dishwasher, as they may suffer crazing or other types of damage. Similarly, do not put items with pre-existing damage, such as hairline cracks, in the dishwasher, as they could shatter.

While Denby stoneware is generally safe to be washed in the dishwasher, some people prefer to hand wash their items to ensure their longevity. Hand washing can be especially useful for removing metal cutlery marks, which can usually be removed with ceramic hob cleaners that contain citric acid. Stacking plates directly on top of each other, rather than sliding them into the middle of a stack, can also help prevent buffing to the glaze and reduce the risk of chipping. Overall, while Denby stoneware is dishwasher-safe, following these care tips can help maintain the condition and appearance of your items over time.

Use liquid detergent and rinse aid to prevent residue

When it comes to dishwasher safety, the general consensus is that items that can withstand high heat, wash sprays, and detergent without damage are considered safe. While Denby stoneware tableware is often advertised as dishwasher-safe, there are a few precautions you should take to ensure the best care for your Denby products:

First and foremost, use liquid detergent. Powdered or tablet detergents can be abrasive and leave a residue on your Denby products. Liquid detergents, such as Finish liquid, are a better choice. Additionally, always use a rinse aid. This crucial step helps prevent mineral deposits from forming on your Denby items during the final hot rinsing stages. The rinse aid creates a protective barrier, ensuring that your Denby pans maintain their quality and appearance.

If you live in an area with hard water, it's essential to use a water softening product in your dishwasher. Hard water can lead to dulling of the glaze on your Denby pans, making them appear cloudy or covered in a white powdery residue. By using a water softener, you can prevent this issue and maintain the shine of your pans.

Another tip to prevent residue is to wash your Denby pans at the lowest effective temperature. Higher temperatures increase the likelihood of deposits forming over time. Pre-soaking casseroles or washing them separately at a higher temperature can help prevent residue buildup.

By following these guidelines—using liquid detergent, rinse aid, and adjusting the water temperature—you can effectively prevent residue and maintain the quality of your Denby pans while utilizing the convenience of a dishwasher.

Hand-wash antique Denby

If you have antique Denby or anything pre-1950s, it is recommended that you do not put it in the dishwasher as it could cause crazing or damage. Instead, follow these steps to hand-wash your antique Denby:

• Use a small amount of dishwasher liquid or detergent and fill the sink with warm water.
• Soak the Denby items in the sink for a few minutes to loosen any food or grease.
• Gently scrub the items with a soft sponge or cloth, taking care not to scratch the glaze.
• Rinse the items thoroughly with warm water to remove any soap residue.
• Dry the items with a soft cloth or leave them to air dry.

It is important to avoid using abrasive cleaners or scouring pads, as these can damage the glaze. Additionally, do not soak antique Denby items for extended periods, as it may lead to water absorption and discolouration.

By hand-washing your antique Denby, you can help preserve its beauty and ensure it lasts for many years to come.

Denby products are lead and cadmium-free

Denby claims that no lead or cadmium is used during the manufacturing process of any of its products. However, some of its products are manufactured in China, which has raised concerns about the presence of these toxins.

Lead and cadmium are toxic heavy metals that can pose serious health risks, especially to children. Lead accumulates in bones, displacing calcium, while cadmium exposure can cause kidney disease, lung damage, cancer, and fragile bones.

While Denby's statement on lead and cadmium-free manufacturing is reassuring, it is always advisable to be cautious and prioritize the use of glass, stoneware, and products from trusted manufacturers with transparent testing procedures.

Denby glazes do not craze or crack

Denby has been producing high-quality dishes for over 200 years. Their products are lead and cadmium-free, with glazes that will not craze or crack. The high firing temperature vitrifies the stoneware, making it durable and chip-resistant. The glazes are also designed so that they cannot absorb foods or fluids, resulting in a very hygienic product.

Modern Denby products are generally dishwasher-safe. However, there are a few precautions to take to avoid damage and keep your Denby stoneware in the best condition. Firstly, if you live in an area with hard water, certain Denby patterns may be more prone to dulling of the glaze. To avoid this, use a dishwasher liquid detergent rather than powders or tablets, as these can be abrasive before they are fully dissolved. Always use a rinse aid to prevent mineral deposits from forming on your Denby during the final hot rinse. If you are in a hard water area, use a water-softening product in your dishwasher.

When loading your dishwasher, wash Denby items at the lowest temperature possible to effectively clean them. Pre-soak casseroles if you can, or wash them separately at a higher temperature. The higher the wash temperature, the more likely it is that deposits will form over time. Unfortunately, if deposits have already formed on your Denby, there is little that can be done to remove them. However, hand-rubbing with white distilled vinegar may help to improve the appearance.

To avoid potential damage to your Denby items in the dishwasher, ensure they are stacked securely and cannot clatter against each other or move around during the wash cycle. Keep your Denby items away from metal objects such as cutlery and pans, as these can cause damage and leave metal marks. Antique Denby and any Denby items from before the 1950s should not be put in the dishwasher, as this could cause crazing or damage. Similarly, do not put any Denby items with pre-existing damage, such as hairline cracks, in the dishwasher, as they could shatter.
