How To Keep Drinking Glasses From Sweating

Condensation on your glass can leave watermarks on your table. It can also cause your hand to get uncomfortably wet while you drink. If you've been dealing with a sweating glass, you're probably wondering how you can stop this from happening. We've done the research and can tell you how to keep your drinks free of condensation!

A mixture of equal parts vinegar and water sprayed on the outside of your glass can help prevent condensation from forming. You can also try lowering the temperature in your room or using a dehumidifier. Other methods of preventing drinking glass condensation include using covers and buying "sweat-proof" drinkware.

While condensation can be annoying, you can still prevent it! Keep reading to learn more about avoiding condensation, selecting sweat-proof glasses, and more!

Preventing Condensation

One method people use to prevent their drinking glass from sweating is using a vinegar and water mixture. You can either combine these into a spray bottle or a small dish. Then, you'll coat the outside of your glass in the mix. Finally, wipe the combination off and pour your drink.

When using this method, it's important to use equal parts water and vinegar. You can also add in a few drops of dish soap. Dish soap is commonly used as a surfactant. It will change the surface tension of the glass and make it more difficult for condensation to form.

Adjusting Temperature and Humidity

If you're inside, you can change the temperature of your room or use a dehumidifier to help lessen the amount of condensation you get on your glass. Hot air can hold more water vapor than cold air can. As hot air touches a cold surface, it will form into water droplets or dew.

When you lower the temperature in the air, you decrease the amount of water vapor it holds. The lower difference in temperature can mean fewer water drops form on your cup. A dehumidifier will take water from the air without you needing to adjust the ambient temperature.

Keep in mind that these methods are best for lessening the amount of condensation you have. You can't completely stop your cold glass from sweating. However, there are ways to protect your hands and surfaces from getting wet.

Covering Glass Condensation

You can keep your hands protected from condensation by using a glass sleeve. This method also has a few benefits. Glass sleeves can keep your drink colder and protect the cup from damage.

There are a few different styles of glass insulators. You can get ones made out of neoprene, silicone, and terry cloth. Neoprene and silicone will provide the most insulation and protection against condensation. However, you can easily use terry cloth covers with various styles of glasses.

Double-Walled Cups

You won't get any condensation if your cup has a double wall. This style of drinkware is essentially a glass inside a glass. There is insulation between these two walls. Insulation types include air, foam, vacuum, and copper.

Your cup will prevent the transfer of heat between the layers. Air and foam will easily prevent condensation. They don't retain temperature as well as other materials, though.

Vacuum and copper insulation both eliminate the air between the inner and outer walls. Without air, heat can't pass from the outside layer to the inside, and the cold can't get out.

Do insulated glasses sweat?

Insulated glasses are also known as double-wall glasses. This style of drinkware shouldn't sweat. If your insulated cup is sweating, there could be a problem with the vacuum between the layers.

Unfortunately, if your insulated cup starts sweating, you won't be able to repair it. You won't be able to create the same seal that the product initially had. Fortunately, with proper care, insulated glasses typically last many years.

What causes condensation on drinking glasses?

Condensation happens when the cool glass is exposed to warm or hot air. The heat from the air transfers to the glass, cooling the air around the cup. Once the temperature is low enough, the liquid will begin to form on the glass.

Your cup will stop sweating as the difference in temperature between the cup and surrounding air lessens.

Do all drinking glasses sweat?

Unless your drinking glass is double-wall insulated, it will sweat if you put a cold drink in it. This is even true for other kinds of drinks. For example, a cold aluminum can will also sweat when exposed to warm air.

In Conclusion

Dealing with a sweating glass can be a nuisance. Thankfully, there are ways to lessen the amount of condensation on your glass! Remember that you'll eliminate sweating with a double-wall insulated cup. These also have the added benefit of keeping your drink cooler for longer!
