Okay, so you’re staring at the bottom of a mug, a Tupperware lid, or maybe a new pan, squinting at some tiny etched icon, trying to decide if it’s safe to toss in with tonight’s load. Honestly? You’re not alone. This is one of the most common little kitchen mysteries out there. Let’s clear it up properly.
Quick answer: The dishwasher safe symbol is usually a small square or box with a plate or glass inside it, plus water droplets or diagonal lines representing spray. If the droplets only touch the top half of the box, that means top-rack only. No symbol at all? Play it safe and check the manufacturer’s care instructions or hand wash.
Now let’s get into the details because “is this dishwasher safe?” comes up for a lot more than just plates.
What Does the Dishwasher Safe Symbol Actually Look Like?
Here’s the thing that trips people up: there’s no single, universal dishwasher-safe icon that every manufacturer is legally required to use. That said, most brands use something pretty similar:
- A square or box shape.
- A plate, glass, or dish sketched inside.
- Water droplets or diagonal lines above or across it.
- Sometimes the words “top rack” are printed underneath.
If the water lines only hit the top portion of the box, that’s your cue for top rack only, not the bottom near the heating element. And yes, symbols do vary slightly between brands, but that basic combination of a box, dish, and water lines is fairly consistent across many kitchenware products. No icon at all usually means the manufacturer hasn’t indicated that the item is dishwasher safe, or it’s an older item made before care symbols became common. When in doubt, check the manufacturer’s website.
First, How to Load Things Correctly
Before we get into specific items and whether they even have a dishwasher-safe symbol to check in the first place, it’s worth mentioning the correct way to load a dishwasher, since even genuinely dishwasher-safe items can come out damaged if they’re loaded incorrectly:
- Put anything plastic, delicate, or top-rack-only up top, away from the heating element.
- Angle bowls and cups downward, so water doesn’t pool inside them.
- Keep items from nesting or touching too closely. Water needs to reach every surface.
- Load sharp knives handle-up, for safety more than anything else.
Alright, now onto the fun part: is your stuff actually dishwasher safe?
Drinkware: Yeti, Owala, and Nalgene
Is Yeti dishwasher safe? Yes, YETI’s own Rambler FAQ confirms that all Rambler drinking vessels are dishwasher safe. It’s worth disassembling the lid first, though, by removing gaskets and magnets and placing them in the utensil basket so the dishwasher can actually clean every crevice.
Can Owala go in the dishwasher? Mostly, yes, with one caveat. According to Owala’s official FAQ lids are top-rack dishwasher safe, straws can go in the silverware bin, and the cup body is technically dishwasher safe too, but Owala itself recommends hand-washing the stainless steel body to preserve the finish.
Is Nalgene dishwasher safe? Yes, and it’s genuinely one of the easiest bottles to clean this way. Nalgene’s official FAQ states that all their bottles are dishwasher safe. Just keep them on the top rack, away from the heating element.
Is Tupperware dishwasher safe? Generally, yes. According to Tupperware’s official FAQ, most products made after 1979 are dishwasher safe. Check for the symbol on the bottom to be sure, since very old pieces might predate it.
Are Rubbermaid containers dishwasher safe? Yes, on the top rack. Rubbermaid’s own product care pages consistently list its containers and lids as top-rack dishwasher safe.
Is PETG dishwasher safe? Not necessarily. PETG’s heat resistance can vary depending on the specific material formulation and product, so don’t assume that every PETG item is dishwasher safe. Check the manufacturer’s care instructions before putting it in the dishwasher.
Cookware: Stainless Steel, Non-Stick, Carote, and Caraway
Is stainless steel dishwasher safe? Generally, yes, plain stainless steel pots and pans hold up well in the dishwasher. So can you put stainless steel pans in the dishwasher without worry? Mostly, though hand-washing preserves the shine longer if you care about that mirror finish.
Dishwasher-safe pots and pans as a category really come down to the coating, not just the base metal. That’s the real answer people are usually looking for. That’s where things get more brand-specific:
Are non-stick pans dishwasher safe? Technically, sometimes. However, repeated dishwasher cycles can wear down non-stick coatings faster than handwashing does. Most manufacturers recommend handwashing even when the label says dishwasher safe.
Is Carote cookware dishwasher safe? It depends on the collection. Carote labels many of its granite and ceramic non-stick sets as dishwasher safe, but the brand itself recommends handwashing to extend the coating’s lifespan.
Is Caraway dishwasher safe? Here’s a genuinely useful distinction: Caraway’s ceramic non-stick cookware is explicitly not recommended for the dishwasher, per Caraway’s own care guide hand wash only. Their separate stainless steel line, however, is dishwasher safe.
Is the Ninja air fryer dishwasher safe? Usually, yes, though it varies by model. Check your manual to confirm. Most baskets and crisper plates can go in the dishwasher, but frequent cycles can wear the non-stick coating faster than handwashing. Are Ninja Creami parts dishwasher safe? The pints and lids are typically dishwasher safe on the top rack, but the motor base housing the electronics should never go anywhere near water, dishwasher included.
Cutting Boards
If you’re shopping for the best dishwasher-safe cutting board, plastic and composite boards are your best bet. Wood can warp and crack in a dishwasher, no matter how nice it looks on your counter. Looking for a non-toxic cutting board dishwasher-safe option specifically? Look for BPA-free polypropylene boards labeled dishwasher safe, rather than assuming any plastic board qualifies. That label is your dishwasher-safe symbol, essentially, for that particular product.
Quick Bonus: Cycle Times
Slightly off-topic, but since we’re talking dishwashers, how long does a Whirlpool dishwasher take? According to Whirlpool’s official product help page, a normal cycle typically runs 2 to 3 hours, while a quick wash can finish in about an hour. Worth knowing if you’re loading up delicate items and want to time it around a shorter, gentler cycle.

FAQ
What if there’s no dishwasher-safe symbol at all?
Hand wash it or check the manufacturer’s care instructions first. No symbol usually means the manufacturer hasn’t confirmed that the item is dishwasher safe, or it’s an older item that doesn’t have a care symbol.
Do all dishwasher-safe symbols look the same?
There’s no single official standard for the dishwasher-safe symbol, but the box-plus-water-droplets design is a common version.
Is it safe to assume stainless steel is always fine?
Mostly, yes, for plain stainless steel. Coated or non-stick versions are a different story, so check for coating-specific instructions.
Can I test an item myself if I’m not sure?
It’s better not to test an uncertain item in the dishwasher. Instead, check the manufacturer’s care instructions or contact the manufacturer to confirm whether it’s dishwasher safe.
What about specific brands people ask about a lot?
A few quick ones, since they come up constantly: can Owala go in the dishwasher? Yes, lids and straws can go in the dishwasher, while the body is technically fine but hand washing is recommended. Is Tupperware dishwasher safe? Generally, yes, for most products made after 1979, but check the symbol or care instructions on the specific item. And dishwasher-safe pots and pans in general? Check the coating, not just the metal, since that’s what often determines whether they should go in the dishwasher.
