Plastics and dishwashers have always been a questionable combination. It includes a lot of confusion, uncertainty, and doubts. We are here to lessen the questions and give more answers. This blog will solve the mystery- can you put plastic in the dishwasher or not? We hope to save you from a melted container mess. That’s why let us save you from making the same mistakes.
The Quick Answer
We know you want a simple yes or no answer. But unfortunately, it is a little bit more complicated than that. It is more like “yes, but…”. To understand it easily, you can think of your plastic containers as different types of clothes. When you wash them you wouldn’t wash your silk shirt with your heavy-duty jeans, right? Similarly, not all plastics can handle the same dishwasher washing. Some plastics are tougher and others are delicate like your favourite sweater.
Understanding The Mysterious Dishwasher-Safe Symbols
Have you ever flipped over your plastic container and felt like you were reading an ancient script? But those tiny symbols at the bottom actually give you important information. The dishwasher-safe symbol (those little plates with water drops) is your green light for dishwasher use. But here’s something you don’t realise- even without this symbol, you can know about your plastic’s dishwasher compatibility by knowing its recycling number.
For example, plastics are differently marked. If your plastic is marked with #5 (polypropylene) is usually dishwasher-safe. They are used in those quality meal prep containers that are okay with the heat. But, plastic marked #1 (like those single-use water bottles) can release harmful chemicals when heated – definitely keep them far away from your dishwasher.

The Safe List: Your Dishwasher’s Best Plastic Friends
Plastics that can handle the hot and steamy environment of your dishwasher:
- Heavy-duty food storage containers with dishwasher-safe symbols.
- Quality plastic mixing bowls with the right symbol.
- Sturdy plastic utensils marked for dishwasher use.
- Name-brand food storage containers.
- Hard plastic kid’s dishes designed for dishwasher use.
If you notice, the key is to know about the quality of the plastic. If it feels too lightweight, then it’s better to handwash it. The sturdy meal prep containers are good to go in dishwashers. But that takeout container from last night? Absolutely not.
The No-Go List: When Hand Washing Is Non-Negotiable
Let’s just agree on never putting these in your dishwasher and save yourself the headache:
- Single-use takeout containers
- Disposable plastic plates and cups
- Thin plastic storage containers
- Anything marked as ‘hand wash only’.
- Containers that feel soft or bendy.
A good piece of advice is not reusing and dishwashing takeout containers. They end up warping, and some even melt into the heating element which creates a mess and a safety hazard. Save your kitchen from smelling like plastic for days.

Smart Loading Strategies
Even with dishwasher-safe symbols, you need to be careful where you are putting your plastics in the dishwasher.
- Always use the top rack. It is actually a safer zone for plastics. The dishwasher usually gets hot during cycles. Heat rises, but the heating element is usually at the bottom of the dishwasher. So, putting them on the top rack will have them in a slightly cooler environment.
- Skip the heated dry cycle. It’s better that they come out as they went in!
- Leave space between items to have good air circulation. This will also keep your plastics from melting.
- Secure lightweight pieces so that they don’t flip or move around during cycles.
- Remove items immediately after washing.
Extending Your Plastic’s Life: Beyond Basic Care
Taking care of dishwasher-safe plastics is more than looking at their quality or putting them on the top rack of the dishwasher. A dishwasher can have shifting temperatures. It goes up as high heat that can be not-so-good for your plastics. For instance, letting hot leftovers cool before putting them in plastic containers. Then, letting those containers reach room temperature before washing them, can extend their life.
Think of it like taking care of a good car – regular maintenance and careful use will keep it running smoothly for years. The same thing applies to your plastic containers. A little extra attention can save your plastic containers!

When to Say Goodbye: The Clear Signs
Just because something starts as dishwasher-safe doesn’t mean it stays that way forever. Look for these warning signs:
- Cloudy or filmy appearance
- Warping or change in shape
- Cracks or chips
- The strong plastic smell after washing
- Sticky or oily residue that won’t wash away
These changes can indicate that the plastic is breaking down and might release unwanted chemicals into your food.

Follow the right steps by putting it on the top rack, not using the heated dry cycle and other steps we talked about.
