Bakeware with special coatings or finishes often requires hand washing. For instance, non-stick, ceramic, and enameled coatings can be damaged by the dishwasher’s heat and detergents.
What are the Risks of Putting Bakeware in the Dishwasher?
Putting bakeware in the dishwasher, especially if it’s not dishwasher-safe, carries several risks. The most common issues include warping, discoloration, damage to non-stick coatings, and rust. These problems can affect both the appearance and functionality of your bakeware.
Warping and Distortion
High heat can cause bakeware to warp or distort. This is especially true for thinner metal pans. A warped pan may not heat evenly, leading to inconsistent baking results.
Temperature Sensitivity
Different materials have different temperature tolerances. Exceeding these limits in the dishwasher can cause permanent deformation. For example, some aluminum pans may warp at temperatures above 450°F.
Rapid Temperature Changes
Dishwashers involve rapid temperature changes, from hot wash cycles to cooler rinse cycles. These sudden shifts can stress the material, leading to warping over time.
Discoloration and Staining
Dishwasher detergents can sometimes react with the metals used in bakeware. This can cause discoloration, staining, or a dull appearance. Aluminum, in particular, is prone to this type of reaction.
Chemical Reactions
Some detergents contain harsh chemicals that can react with certain metals. This can lead to dark spots, streaks, or an overall change in color. These stains may not affect performance but can be unsightly.
Hard Water Stains
In areas with hard water, mineral deposits can build up on bakeware during dishwasher cycles. These deposits can leave white or cloudy stains that are difficult to remove.
Damage to Non-Stick Coatings
The non-stick coating is one of the most vulnerable parts of bakeware in a dishwasher. High heat, abrasive detergents, and even the force of water jets can degrade the coating, reducing its effectiveness.
Heat Degradation
Many non-stick coatings have a maximum temperature they can withstand. Dishwashers often exceed this limit, causing the coating to break down or blister.
Abrasive Wear
Dishwasher detergents can be abrasive. Over time, this can scratch or wear away the non-stick surface, making it less effective and potentially releasing harmful particles into food.
Rust and Corrosion
For materials prone to rust, like cast iron or some types of steel, the dishwasher can be a disaster. Moisture, combined with detergent, can quickly lead to rust formation, especially if the bakeware isn’t dried immediately.
Moisture Exposure
Dishwashers are wet environments. Even after the drying cycle, some moisture can remain, creating an ideal environment for rust to develop.
Detergent Residue
If not rinsed thoroughly, detergent residue can trap moisture against the metal. This can accelerate the rusting process, especially in crevices or corners.
How Can I Tell if My Bakeware is Dishwasher-Safe?
Determining whether your bakeware is dishwasher-safe involves a few steps. The most reliable method is to check the manufacturer’s instructions. Look for symbols or labels on the bakeware itself or its packaging.
Checking Manufacturer’s Instructions
Manufacturers often provide care instructions either on the product, its packaging, or their website. These instructions are the most accurate source of information regarding dishwasher safety.
Packaging and Labels
When you first purchase bakeware, keep the packaging. It often contains important care information, including whether the item is dishwasher-safe. Look for phrases like “Dishwasher-Safe” or symbols indicating dishwasher compatibility.
Online Resources
If you no longer have the packaging, check the manufacturer’s website. Many companies provide detailed product information and care instructions online. You can usually find this information on the product page or in a dedicated FAQ section.
Identifying Dishwasher-Safe Symbols
Many manufacturers use specific symbols to indicate if an item is dishwasher-safe. These symbols can usually be found on the bottom of the bakeware.
Common Symbols
A common dishwasher-safe symbol is a square with dishes inside, often with water droplets or diagonal lines indicating water. Variations of this symbol may include a number representing the maximum safe temperature or a specific rack placement recommendation.
Symbol Variations
Some symbols may show a plate with water droplets above it, while others might depict a dishwasher rack. If you’re unsure about a symbol’s meaning, refer to the manufacturer’s website or contact their customer service.
Understanding Material Properties
If you can’t find specific instructions, understanding the general properties of different materials can provide some guidance. As a rule of thumb, stainless steel and silicone are usually dishwasher-safe, while cast iron and untreated aluminum are not.
Stainless Steel
Stainless steel is known for its durability and resistance to high temperatures and corrosion. It’s generally safe to assume that stainless steel bakeware can go in the dishwasher. However, decorative finishes or non-stick coatings on stainless steel might change this.
Aluminum
Aluminum’s dishwasher safety depends on whether it’s anodized. Anodized aluminum has undergone a process that makes it more durable and resistant to corrosion, so it’s often dishwasher-safe. Plain aluminum, however, can react with detergents and discolor.
Non-Stick
Non-stick bakeware is a gray area. Some newer non-stick coatings are designed to withstand dishwasher use, but many are not. The high heat and harsh detergents can degrade the non-stick surface over time.
Glass
Most tempered glass bakeware is dishwasher-safe. Tempering is a process that strengthens glass, making it resistant to thermal shock. However, very delicate glassware or items with painted designs should be hand washed.
Silicone
Silicone is generally considered dishwasher-safe due to its high heat resistance. It can usually withstand temperatures well above what’s found in a dishwasher. However, check for any specific care instructions, especially for molds with intricate designs.
Cast Iron
Cast iron should never be put in a dishwasher. The prolonged exposure to water and detergent can strip away the seasoning that protects the iron, leading to rust. Always hand wash and carefully dry cast iron bakeware.
When in Doubt, Hand Wash
If you’re uncertain about whether a piece of bakeware is dishwasher-safe, the safest approach is to hand wash it. Hand washing may take a bit more time, but it significantly reduces the risk of damage.

Proper Drying
After hand washing, dry your bakeware thoroughly with a clean towel. This helps prevent water spots and, for certain materials, rust. For items with hard-to-reach corners, air drying upside down on a dish rack can be effective.
What are the Best Practices for Cleaning Bakeware in the Dishwasher?
If your bakeware is indeed dishwasher-safe, following best practices can help minimize potential damage and extend its lifespan. Proper loading, detergent choice, and cycle selection are key factors. It’s also important to consider the placement of your bakeware in the dishwasher.
Proper Loading Techniques
How you load your bakeware into the dishwasher can impact cleaning effectiveness and the risk of damage. Avoid overcrowding, ensure proper spacing, and secure items to prevent movement during the cycle.
Avoid Overcrowding
Overcrowding can prevent water and detergent from reaching all surfaces, leading to poor cleaning. It can also cause items to rub against each other, potentially causing scratches or other damage. Make sure there’s enough space between items for water to circulate freely.
Secure Placement
Place bakeware securely on the racks to prevent it from moving during the wash cycle. Movement can cause banging against other items, leading to chips, dents, or scratches. Most dishwashers have specific slots or areas designed for trays and larger items.
Angling for Drainage
Angle items like baking sheets and muffin tins slightly downward. This helps water drain off more effectively, reducing the chance of water spots and speeding up the drying process. It also prevents water from pooling in concave areas.
Choosing the Right Detergent
The type of detergent you use can affect your bakeware. Milder detergents are generally safer for most materials. Avoid detergents with harsh chemicals or abrasive ingredients, especially for non-stick or coated bakeware.
Liquid vs. Powder
Liquid detergents are often gentler than powder detergents. Powder detergents can sometimes be abrasive, especially if they don’t fully dissolve. If you prefer powder, make sure it’s fully dissolved before the main wash cycle begins.
Avoiding Harsh Chemicals
Look for detergents that are free of chlorine bleach and phosphates. These chemicals can be harsh on certain materials, causing discoloration or damage to coatings. Many eco-friendly detergents are formulated to be gentler while still providing effective cleaning.
Selecting the Appropriate Cycle
Choosing the right dishwasher cycle can make a difference. Lower temperature settings and shorter cycles are often gentler on bakeware. Use the appropriate setting based on how soiled your bakeware is.
Gentle or Delicate Cycle
If your dishwasher has a gentle or delicate cycle, consider using it for bakeware. These cycles typically use lower temperatures and less water pressure, which can help protect more delicate items. They’re often suitable for lightly soiled bakeware.
Normal Cycle
For moderately soiled bakeware, the normal cycle is usually sufficient. This setting provides a good balance between cleaning power and gentleness. Most dishwasher-safe bakeware can handle the normal cycle without issues.
Heavy-Duty Cycle
Reserve the heavy-duty cycle for extremely soiled items. This cycle uses high temperatures and strong water pressure, which can be too harsh for some bakeware. It’s best used for pots and pans with baked-on food that requires extra cleaning power.
Top Rack vs. Bottom Rack
Where you place your bakeware in the dishwasher can matter. The top rack is generally gentler, while the bottom rack experiences higher heat and water pressure. Some bakeware, like glass and items with non-stick coatings, may fare better on the top rack.
Top Rack Advantages
The top rack is further from the heating element, resulting in a lower temperature during the drying cycle. This makes it a safer spot for items that are sensitive to heat. It’s often recommended for plastics, delicate glassware, and some types of non-stick bakeware.
Bottom Rack Considerations
The bottom rack is closer to the heating element and typically experiences the strongest water jets. This makes it suitable for durable items like stainless steel baking sheets. However, be cautious about placing delicate or heat-sensitive items on the bottom rack.
Rinsing and Drying
Proper rinsing and drying can help maintain your bakeware’s appearance and prevent water spots. Make sure your dishwasher’s rinse aid dispenser is filled to help with drying. If possible, air-drying can be a gentle alternative to the dishwasher’s heat-drying cycle.
Rinse Aid Use
Rinse aids help water sheet off dishes, reducing water spots and speeding up drying. They can be especially beneficial for bakeware, which often has large flat surfaces where water spots are noticeable. Make sure your dishwasher’s rinse aid dispenser is filled and properly adjusted.
Air Drying
If you want to be extra cautious, especially with non-stick or coated bakeware, consider air drying. After the wash cycle, open the dishwasher door and pull out the racks, allowing the items to air dry. This eliminates the heat from the drying cycle, which can be harsh on some materials.
