Can You Put Washing Machine Tray in Dishwasher? A Practical Guide
Learn whether a washing machine tray is dishwasher-safe, the risks involved, safe cleaning methods, and practical alternatives. This guide provides step-by-step instructions and expert tips from Best Washing Machine.
You should not assume a washing machine tray is dishwasher-safe. Most trays are made from plastics or coatings that warp, discolor, or release chemicals in high heat or with strong detergents. The recommended approach is hand-washing with mild soap, then thorough air-drying. If the tray is clearly labeled dishwasher-safe, use a gentle cycle on low heat.
What is a washing machine tray and why care?
A washing machine tray, often called a drip tray or protective catch pan, is designed to sit beneath or around your washer to collect spills, leaks, and condensation. It protects floors, reduces cleanup time, and helps you spot leaks early. According to Best Washing Machine, regular maintenance of this tray prevents hidden mold and water damage, especially in small laundry rooms where moisture lingers. The most common materials are plastic, rubber, and metal; each material has different dishwasher and cleaning implications. Plastic trays are light and affordable but can warp if exposed to high heat; rubber trays may stain or slip if cleaners are too harsh; metal trays resist warping but can corrode if not cared for properly. Before deciding how to clean, inspect the tray for labels, drainage holes, and signs of wear. If there are embossings or symbols, they may indicate whether dishwasher cleaning is allowed. As a practical matter, you should tailor your approach to the material, the tray’s age, and the environment around your washer. If the tray sits on a hard floor and collects water regularly, a clear, heat-resistant tray with sealed edges is preferable. By understanding these basics, you’ll choose cleaning methods that preserve the tray’s integrity while keeping your laundry area safe and tidy. In many households, the tray is a simple, 1-2 inch deep dish that captures drips from hoses, seals, and the washer door. Always treat a suspected leak seriously; addressing it early can prevent costly water damage.
Can you put washing machine tray in dishwasher?
The short answer is: not as a default rule. Most trays are not designed to withstand dishwasher heat, aggressive detergents, or the physical agitation inside a dishwasher. Common plastic trays can warp or warp irreversibly, adhesives or seals can fail, and metal trays may corrode. Even when a tray is marketed as dishwasher-safe, ensure you follow the label instructions precisely. If care labels explicitly state dishwasher-safe, use the gentlest program available, place the tray on the top rack away from the heater element, and avoid high-heat drying. If there is any doubt, treat the tray as non-dishwasher-safe and stick to hand-washing. This approach minimizes the risk of permanent damage and keeps your washer area free from unexpected failures. For many households, manual cleaning is quick, effective, and gentler on materials over time. The key is consistency: clean regularly, dry thoroughly, and store in a location that minimizes exposure to moisture. The decision also depends on the tray’s location and use: frequent leaks or seasonal maintenance may warrant more frequent cleaning checks.
Materials and dishwasher compatibility
Tray materials vary widely, and compatibility with the dishwasher is not guaranteed. Plastic trays made from low-grade polymers can warp or melt if exposed to heat. Rubber trays prone to staining and chemical absorption may degrade under aggressive detergents. Metal trays, while durable, can rust or scratch if the dishwasher’s rinse aids are harsh. The general rule of thumb is that unless you see a clearly labeled dishwasher-safe symbol, you should not place the tray in the dishwasher. The label, mold markings, or manufacturer instructions provide the safest guidance. If your tray has a protective coating, finishes, or nonstick surfaces, dishwasher exposure can diminish those coatings quickly. When in doubt, favor hand-washing with mild soap and a soft brush, followed by thorough drying. These safer steps will extend the life of the tray and help maintain the cleanliness of your laundry area without risking dishwasher damage. From a maintenance perspective, avoiding dishwasher temperatures for trays that aren’t explicitly approved helps protect your investment and reduces the chance of leaks.
How to test dishwasher-safety of a tray
Testing a tray’s dishwasher-safety without risking the entire tray involves careful steps. First, locate any care labels or symbols on the tray. If a dishwasher-safe symbol is present, proceed with caution on a short, cold or warm cycle using the top rack. If no symbol exists, start with a manual test on a small, inconspicuous corner—wash it in the dishwasher using a mild cycle on the lowest heat setting and monitor for warping, discoloration, or material failure after the cycle. If the tray remains unchanged, you can consider a full testing cycle with the same gentle settings. Avoid aggressive detergents and high-heat drying during testing. Always let the tray cool completely before inspecting for warping or distortion. If any change occurs, discontinue dishwashing and revert to hand-washing. Best practices suggest documenting the tray’s performance after the test so you can make informed decisions in the future.
Safe cleaning methods (hand-wash) and sanitation
Hand-washing is typically the safest method for washing machine trays that lack a dishwasher-safe label. Use warm water and a mild dish soap, then scrub with a soft-bristle brush or sponge to remove soap scum and mineral deposits. Rinse thoroughly to remove all soap residues, which can attract dirt or cause surface wear over time. Dry with a clean microfiber cloth and allow the tray to air-dry completely before placing it back under or around the washer. For stubborn stains, create a gentle soak with warm water and a tiny amount of baking soda or white vinegar, then rinse well. Avoid abrasive cleaners that can scratch or dull coatings. Regular maintenance, including inspection for cracks or warping, helps prevent leaks and protects your flooring. The emphasis on hand-washing not only preserves the tray but also minimizes chemical exposure to your washer and clothing. By adopting consistent cleaning routines, you’ll extend the life of the tray and maintain a tidy laundry environment.
Alternatives to dishwasher cleaning
If you’re unsure about dishwasher safety and want a quick-clean method, consider soaking the tray in a basin of warm, soapy water for 10–15 minutes, then scrubbing with a soft brush. For mineral deposits, a vinegar solution (1:1 vinegar and water) can help loosen buildup, followed by a thorough rinse. You can also use a mild baking soda paste for stubborn spots, then rinse completely. Using a dedicated tray-cleaning brush can help reach seams and corners that are hard to scrub by hand. When possible, remove the tray and clean it in a sink or utility basin away from the washer to prevent accidental contact with electrical components. If you upgrade or replace the tray, look for dishwasher-safe labeling only if you have space to run a low-heat cycle with the top rack. This approach gives you flexibility and reduces the risk of damage to both tray and dishwasher.
What to do if dishwasher damages the tray
If your tray warps, cracks, or shows signs of coating degradation after a dishwasher cycle, discontinue using it in the dishwasher immediately. Remove the tray and switch to hand-washing as the primary cleaning method. Check if the tray is still structurally sound; if deformation is minor, you may be able to use it carefully, but if there is any warping that could affect fit or create gaps, replace it. Contact the manufacturer for replacement parts or warranty guidance if applicable. If the damage creates sharp edges, consider replacing the tray to avoid injury or further leaks. Regularly inspecting for cracks and deformation helps prevent hidden leaks that can damage floors and cabinetry. By acting quickly and thoughtfully, you can preserve your laundry space and avoid costly repairs.
