Can you microwave a red solo cup?

Microwaves are pretty picky when it comes to plastics. Some plastics hold up well, barely becoming soft or malleable. But on the other hand, there are plenty of other plastics that seem to soften just in the presence of a microwave. can you microwave a red solo cup?

So you may be wondering whether or not you can microwave a red Solo mug. It’s a logical question, especially if you’ve ever had a lukewarm cup of tea and wanted to heat it up.

The short answer is no, you can’t microwave a red Solo mug. If you do, the mug will spill or melt, spilling its contents all over the inside of your microwave.

In fact, it is not recommended to drink hot drinks in disposable plastic cups unless they are specifically for hot liquids.

What is a Red Solo cup?

The ubiquitous red Solo cup has become a party staple over the years. They are perfect for all kinds of cold drinks, from apple juice to beer. You’ll find them at birthdays, college parties, and around the house of anyone who wants to skip the plate service once in a while.

But as useful as Solo cups are, they also have their downsides.

Solo glasses are very strong, but are designed for cold drinks or drinks that stay at relatively low temperatures. In other words, if you’re looking for a disposable container for your hot coffee or tea, you should probably look into a paper cup. Or, if you don’t want to be able to reheat your drink, you can also use Styrofoam.

What would happen if you microwaved a Red Solo mug?

The individual mugs are not microwaveable, so if you were hoping to heat up some water for a hot tea in one, don’t. They have a low melting point that almost guarantees you’ll end up with water and melted plastic all over your microwave.

If you only set it down for a few seconds, the plastic might soften, but it’s unlikely to melt. However, even if that were the case, you still risk harmful chemicals being released into your drink.

Most plastics contain bisphenol A, an industrial chemical also known as BPA. You’ve probably seen “BPA free” claims on many packaging labels, and that’s because it can be hazardous to your health.

If a container is designed for cold liquids, any BPA leaching will be minimal. However, if you put hot liquid in a mug that isn’t designed for it, you risk BPA leaching from the plastic into your drink.

What alternatives can you use instead?

Finding a microwave-safe mug isn’t too difficult. Ceramic, Pyrex, and certain heavy-duty plastics and papers are perfectly safe to use in the microwave.

Ceramic pans

work best for reheating hot liquids because they’re usually made of ceramic, which retains heat well. They’re also often the perfect size if you plan to pour your drink into a disposable paper cup.


Pyrex glass is also safe to use in the microwave. For example, if you have a Pyrex measuring cup, you can use it to heat your drink. You can also put your drink in a Pyrex container to reheat.

One important note about Pyrex though. This glass does not withstand extreme temperature changes well. So when you take your Pyrex out of the microwave, don’t put it in an ice bath to cool down, as that could cause the glass to break. If you need to chill your drink, pour it into a mug with ice or let it cool at room temperature.


Not all paper cups are microwave safe, but some are, making them a great disposable alternative to a red Solo cup. Before you microwave one, check the package to make sure it’s safe to do so. Also, avoid putting anything coated in wax in the microwave, as it will certainly melt.

It is not advisable to put hot drinks in a plastic cup only for three main reasons. First, the plastic will become very soft, which could lead to spillage.

Third, the softness of the plastic can make it difficult to get a good grip on the glass because it loses its shape easily.

The soft plastic that is so common for disposable plastic cups will not withstand high temperatures in any setting, including the dishwasher. They will inevitably melt, mainly due to the exposed heating element in the dishwasher. If you want to reuse your mug, simply wash it in the sink.


In summary, you should never microwave a red Solo mug or any mug that is not microwave safe. That includes most disposable plastic, paper, and Styrofoam cups. Even if they’re designed for hot drinks, it’s best to find a microwave-safe ceramic mug and transfer your drink from there.
