A few years ago, I bought a beautiful set of colorful plastic storage containers for my kitchen. Excited to start using them, I loaded the containers straight into my dishwasher—without checking for dishwasher safe symbols. After the cycle, I opened the dishwasher to find warped lids and cracked containers. It was a frustrating lesson learned: dishwasher safe symbols matter.
Ignoring these symbols doesn’t just ruin your kitchenware—it can cost you money. Misunderstanding dishwasher safe markings can lead to damaged products, forcing you to replace items sooner than expected. Since then, I always pay close attention to these symbols, especially when buying plastic items.
The Real Purpose of Dishwasher Safe Symbols on Kitchenware
Ensuring Product Longevity
Dishwasher safe symbols aren’t just small graphics—they’re your guide to protecting your kitchenware. Properly recognizing these symbols ensures your items remain in good condition for years. Without this knowledge, kitchenware can easily warp, crack, or become discolored from exposure to harsh dishwasher cycles.
Plastic kitchenware is particularly vulnerable to dishwasher damage. Plastics react differently under heat and detergents; some plastics can handle heat well, while others easily deform or degrade. Dishwasher safe symbols on plastic clearly indicate whether the product can handle the heat and pressure, significantly extending its lifespan.
Health and Safety Considerations
Beyond protecting your kitchenware, understanding dishwasher safe symbols also safeguards your health. Many plastics can release harmful chemicals when exposed to dishwasher heat and aggressive detergents, potentially contaminating your food.
Recognizing dishwasher safe symbols on plastic products helps prevent this chemical exposure. By properly interpreting these symbols, you avoid using products that degrade or leach dangerous substances when heated. Always follow these symbols—your health could depend on it.
Recognizing Dishwasher Safe Symbols on Plastic Kitchenware
What Does the Dishwasher Safe Symbol Look Like on Plastic?
On most plastic kitchenware, the dishwasher safe symbol is easy to identify. Typically, it appears as a small dishwasher icon—a square box with plates, cups, or glasses inside—accompanied by small water droplets or spray lines above it.
Sometimes, you’ll also notice words such as “Top Rack Only” next to the symbol. This extra instruction indicates that while the plastic is dishwasher safe, it should only be placed on the top rack to prevent damage from higher heat or stronger water jets in the bottom section.
Why Dishwasher Safe Symbols on Plastic Require Extra Attention
Not all plastics are equal. Different types have varying heat tolerances and chemical stability. This makes dishwasher safe symbols especially crucial for plastic items. Unlike glass or ceramic, plastic can easily degrade or deform if used incorrectly in a dishwasher.
Always verify the dishwasher safe symbol carefully on plastic kitchenware, and double-check for any additional instructions. This extra step ensures your plastics remain safe, undamaged, and free of harmful chemical exposure.
Consequences of Ignoring Dishwasher Safe Symbols
Ignoring dishwasher safe symbols isn’t just inconvenient—it can permanently damage your kitchenware. If you mistakenly assume something is dishwasher safe, you risk warping, cracking, or severe discoloration. Worse yet, plastic items not meant for dishwashers can degrade, leading to chemical exposure and potentially unsafe food-contact surfaces.
This isn’t just theory—I learned it firsthand. Last summer, I overlooked the dishwasher safe symbol on an expensive plastic food storage container. After a single wash cycle, the container was warped beyond use, and its lid no longer sealed properly. What was meant to simplify my kitchen ended up wasting both money and time.
Ever since that incident, I’ve realized how essential it is to double-check those symbols every single time.

Easy Tips to Remember Dishwasher Safe Symbols When Buying Kitchenware
To avoid repeating my past mistakes, I created a simple checklist. Using it helps me quickly identify dishwasher-safe products when shopping:
- Look for clear symbols directly on the product:
Quickly inspect the bottom or sides for the familiar dishwasher icon with plates or glasses and spray lines. - Check online descriptions or packaging for clear instructions:
Many online stores and physical packaging clearly state if an item is dishwasher safe. Always double-check if you’re unsure. - Avoid items without clear care instructions unless willing to hand wash:
When an item doesn’t clearly indicate dishwasher safety, choose another product—or commit to hand washing it. It’s always safer to avoid guessing.
Using this quick checklist has made shopping for dishwasher-safe kitchenware easy and stress-free. Now I confidently purchase kitchen items, knowing exactly how to care for them.
FAQs

Ignoring these symbols can cause plastic kitchenware to deform, crack, discolor, or even release harmful chemicals, significantly shortening its lifespan and compromising food safety.
Can the dishwasher damage plastic items even if they’re marked dishwasher safe?
Yes, some dishwasher-safe plastic items may still require special care, like top-rack placement, to avoid warping or discoloration from high heat or strong detergents.
How can dishwasher safe symbols help prevent chemical exposure?
Dishwasher safe symbols indicate plastics that withstand high heat without releasing harmful chemicals. Always verify the symbol to avoid chemical contamination from degraded plastics.
Where can I usually find dishwasher safe symbols on plastic kitchenware?
These symbols typically appear on the bottom or sides of kitchenware, clearly marked with an icon showing dishes or glasses inside a dishwasher box with water droplets.
Why do some dishwasher safe plastics specify “Top Rack Only”?
The “Top Rack Only” instruction means these plastics are more sensitive to heat. Using the gentler top rack prevents warping or melting during the dishwasher’s cycle
