There’s nothing quite like starting your day with a hot cup of coffee. But when you’re on the go, it can be tough to find a good place to get your caffeine fix. That’s where McDonald’s comes in.

However, when you are travelling from McDonald’s to your home or office space, your coffee might get cool down. So, the next thing most people wonder is whether McDonald’s coffee cups microwave safe.

The truth is since the inside of the MacDonald’s cup is finished with wax and plastic, it’s advised not to microwave.

In this article, we’ll go over everything you need to know about microwaving McDonald’s coffee cups.

What Are McDonald’s Coffee Cups Made of?

The vast majority of McDonald’s coffee cups are made out of virgin polypropylene. Polypropylene is a type of plastic that is durable and heat-resistant. It’s also transparent, which makes it ideal for holding hot liquids like coffee.

Your McDonald’s coffee cup is a container made with wax lining on the inside of the cup. So, the virgin polypropylene that McDonald’s coffee cups are made out of, will hold your hot or cold brew for a certain time.

What if You Microwave McDonald’s Coffee Cups?

If you microwave your McDonald’s coffee cup, the wax lining will start to melt. This can cause the chemicals in the wax to leach into your coffee.

Additionally, the virgin polypropylene that the cup is made out of can start to break down when exposed to high temperatures. When this happens, harmful chemicals can be released into your coffee.

So, while microwaving your McDonald’s coffee cup might heat up your coffee, it’s not worth the risk. It’s best to just wait for your coffee to cool down or transfer it to a different container before microwaving it.

How to Reheat Your McDonald’s Coffee?

There are two ways to reheat your McDonald’s coffee. You can either use your kitchen stove or your microwave.

If you’re using your kitchen stove, simply put your coffee in a pot, keep it on the burner, and heat it on low until warm. 

If you’re using your microwave, simply put your coffee in a microwave-safe container, place it in the microwave and heat it on low for 30 seconds to 1 minute or until warm.

Enjoy your coffee!

Is McDonald’s Coffee Cups Reusable?

McDonald’s coffee cups are reusable two or three times, depending on how safely you use them. However, you can recycle them. Recycling McDonald’s coffee cups helps to reduce waste and conserve resources.

If you’re looking for a reusable coffee cup, there are many options available on the market. Some reusable cups even come with a discount at participating cafes. Consider investing in a reusable cup to help reduce waste and save money in the long run.

Bottom Line

Microwaving your McDonald’s coffee cup is not recommended. The virgin polypropylene that the cup is made out of is heat-resistant, but the wax lining can start to melt and leach chemicals into your coffee.

Additionally, polypropylene can start to break down and release harmful chemicals into your coffee when exposed to high temperatures. So, it’s best to just wait for your coffee to cool down or transfer it to a different container before microwaving it.

1. Are coffee cups microwave safe?

If you need to reheat your coffee in the microwave, it’s best to use a ceramic or glass mug.

2. What happens if you microwave a cup that says do not microwave?

Answer: If the mug is unglazed, microwaving it may cause the bottom to become hot and even melt. Glazed ceramics are usually safe to microwave, but be sure to read the manufacturer’s guidelines. Some mugs are specifically designed for microwaving, and these will have a Microwave Safe symbol on them.

3. Why do Mccafe cups say do not microwave?
