I often see labels indicating that items are dishwasher-safe or microwave-safe. But do these labels mean the same thing?
So if a cookware is dishwasher safe, is it also microwave safe and vice versa?
I decided to find out the differences so I don’t end up ruining my cookware.
What Do You Mean By Dishwasher Safe?
When you hear the term “dishwasher safe,” it refers to items that can be safely cleaned in a dishwasher without being damaged or causing harm.
These items can withstand high heat, strong water sprays, and detergents used in the cleaning process.
In many cases, it’s usually indicated on the product’s label or packaging with a symbol, such as a triangle with a dot in the middle source.
What Does Microwave Safe Mean?
When a product is labeled as microwave-safe, it means that the item has been tested to withstand the heat and energy waves produced by a microwave.
It will not melt, warp, or release harmful chemicals. You can rely on microwave-safe products for their ability to heat up quickly and evenly.
It’s important to note that microwave-safe dishes are specifically designed to be used inside a microwave.
The microwave-safe symbol appears as a square with wavy lines inside of it, on the back of a dish or container.

Does Dishwasher Safe Mean Microwave Safe?
Usually, items that are microwave-safe are also dishwasher-safe. For example, microwave-safe plastic containers typically can handle the dishwasher too.
However, this doesn’t necessarily indicate that they are also microwave-safe.
While many microwave-safe dishes are dishwasher-safe and vice versa, these features are not always directly correlated.
For example, some ceramic dishware may be safe in the microwave but could have hand-painted or metal-rimed decorations that make them unsuitable for the dishwasher.
It’s always good to check the labels or packaging of each product to prevent potential damage or safety issues.

How to Know if Something is Microwave Safe?
To determine if your dishes are safe to use in the microwave, follow these guidelines.
Look For Microwave Safe Labels
First, look for any labels or symbols on the dish that indicate it is microwave safe.
Microwave-safe symbols can vary, but they often include wavy lines, which represent radiation waves.
Some symbols might show an image of a microwave or a dish set below the waves.
These markings indicate that the particular item is safe to use in a microwave.
Additionally, you may find written phrases like “Microwave Safe” or “Microwave Approved” on the item.
Perform a Test
If there are no visible labels, you can perform a test to check if the dish is microwave safe. Fill a microwave-safe cup three-quarters full with water.
Place the cup and the dish you want to test in the microwave, ensuring they don’t touch each other. Microwave them on high power for one minute.
If the dish remains cool or only slightly warm, it is likely microwave-safe. However, if the dish becomes hot, it’s not suitable for microwave use.

Find Out the Material
Material is another factor to consider when determining if something is microwave safe. Common microwave-safe materials include glass, ceramic, and most plastics.
Aluminum foil and some plastics are not microwave safe, as they can cause sparks, damaging your microwave.
If the material has a gold or silver rim, a metal lining, or decor, it is not microwave safe.

How to Know if Something is Dishwasher Safe?
When trying to determine if an item is dishwasher safe, begin by looking for any markings or labels on the dish.
Look For Dishwasher Safe Labels
Often, the words “Dishwasher Safe” or a specific dishwasher safe symbol will be present. Dishwasher safe symbols usually depict a square box with plates, glasses, or both inside.
Sometimes these symbols may also display water droplets or diagonal lines representing water, to indicate the item is safe for dishwasher use.
Check the bottom of your dishware for these symbols, as some items might have specific markings for top rack dishwasher safe only.
Keep in mind that not all dishware is dishwasher safe. If you see a circle with a line through it, this means the item should not be used in a dishwasher.
A square with a line through it signifies that the dishware is safe for handwashing cycles only.

What Happens If You Microwave a Non-Microwave Safe Material?
When you microwave a non-microwave-safe material, several issues can arise. For instance, materials like plastic might release harmful chemicals when heated.
These chemicals can potentially contaminate your food, posing health risks. It’s important that your dish is labeled as microwave-safe to avoid such problems.
Using non-microwave-safe materials, like metals, in the microwave can cause more severe issues.
Metal dishes can catch fire, damaging not only the dish but also your microwave, or even causing injuries.
Remember that microwaves work by reflecting microwaves off metal surfaces, so introducing one could lead to an uneven distribution of heat, resulting in hotspots.
Ceramic dishes that are not microwave-safe may contain lead or other harmful materials.
When heated in a microwave, those substances can leach into your food, causing potential health hazards.
Besides, non-microwave-safe ceramics might not withstand the intense heat and could crack, break or explode, leading to a mess and possibly injuries.
Lastly, when it comes to glass, it is generally safe to use in the microwave. However, not all glassware is microwave-safe.
Some glass containers might have impurities or air bubbles that expand upon exposure to heat. This can cause the glass to crack or shatter, posing a danger to you and your appliance.

What Happens If You Use a Non-Dishwasher Safe Item in the Dishwasher?
Sometimes, you might accidentally place a non-dishwasher-safe item in your dishwasher.
While this isn’t ideal, it’s important to understand the possible consequences and how to avoid them in the future.
One common issue is that the paint or decoration on certain dishes, such as fine china, can chip or wear off due to the abrasive nature of dishwasher detergent and high heat.
Therefore, it’s best to hand-wash fragile items like these to preserve their appearance.
Additionally, placing non-dishwasher safe dishes in the dishwasher can cause some plastics to warp or become discolored, as these materials may not be able to withstand the high temperatures.
Wooden items, such as cutting boards, can also crack and warp due to the combination of heat and moisture.
In some cases, using non-dishwasher-safe items can even result in damage to the dishwasher itself.
Heavier or bulky items can interfere with the spray arms or bend the dishwasher racks, leading to poor cleaning performance or further complications.
