What is Windex?

Windex is a blue-colored glass and surface cleaner that most people use to clean windows and other glass surfaces. It’s often used to remove fingerprints, smudges, and other dirt from surfaces.

It’s one of the most popular window cleaners on the market and is known for its streak-free shine.

Windex is owned by SC Johnson, a family-owned company based in the United States. The company was founded in 1886 and is currently run by the fifth generation of the Johnson family.

It’s important to note that Windex should not be used on all surfaces. You should avoid using it on surfaces that are sensitive to chemicals, such as wood or other varnished surfaces.

What Ingredients are in Windex?

Widex is composed primarily of water, ethylene glycol, ammonia, dye, and fragrances. The exact ingredients vary depending on the type of Windex you’re using.

It’s important to note that not all Windex is made the same.

For example, the original blue formula contains these ingredients:

  • Water
  • 2-hexoxyethanol
  • Isopropanolamine
  • Sodium dodecylbenzene sulfonate
  • lauramine oxide
  • ammonium hydroxide
  • fragrance
  • Liquitint sky blue dye

Depending on the specific formula, Windex may also contain ingredients like hexoxyethanol, alcohol, ammonium hydroxide, and ethylenediamine.

Is There Ammonia in Windex?

Windex contains ammonia, which is a common ingredient in cleaning products. Ammonia is a colorless gas that has a strong smell. It’s often used in cleaning products because it’s good at breaking up dirt and grime.

Windex also contains other ingredients like alcohol and water. These ingredients help to dilute the ammonia and make it safer to use.

Is Windex Just Vinegar?

Vinegar is not the only ingredient in Windex. Some Windex products contain vinegar, but not all of them. The original blue Windex formula does not contain vinegar.

However, there are other formulas that do contain vinegar. For example, the Windex Vinegar Glass Cleaner is one product that contains vinegar.

The Windex Vinegar Glass Cleaner is made with vinegar and doesn’t have the smell of ammonia. It’s safe to use on most surfaces, including windows, mirrors, glass, and even toilets!

How Long Does Windex Last?

On average, an unopened bottle of Windex will last for two years before it expires. Once you open the bottle, the shelf life is cut down and it will only last for about six months to a year or more depending on how it’s stored.

It’s important to note that these are just averages and your specific bottle of Windex may last longer or shorter depending on how you store it.

For example, if you store your Windex in a cool, dark place, it will last longer than if you store it in a warm, sunny place.

The expiration date is usually printed on the bottom or back of the bottle. Once the bottle is opened, you should write the date on the bottle so you know how long it’s been open.

How to Store Windex Properly

Windex should be stored in a cool, dark place like a cupboard or pantry. You should also make sure the bottle is tightly closed when you’re not using it. This will help keep the Windex from evaporating and prevent it from expiring sooner than usual.

When storing Windex, you should also avoid exposing it to extreme temperatures. If the temperature is too cold, the Windex may freeze and become unusable. If it’s too hot, the heat can cause the chemicals in the Windex to break down and expire sooner.

It’s important to also keep your Windex away from any heat sources like stoves, ovens, or radiators.

What Happens When Windex Expires?

When Windex expires, the chemicals in the cleaner can break down and become less effective. The Windex may also lose its color and turn yellow or brown.

You may also notice the texture of the Windex change and it may become runnier or thicker than usual.

If you notice any of these changes, it’s best to throw out the expired Windex and buy a new bottle.

Can You Use Expired Windex?

It’s not recommended to use expired Windex because the chemicals in the cleaner can break down and become less effective. It may also cause streaking or other problems on surfaces.

If you do use expired Windex, be sure to test it in a small area first to see if there are any adverse effects.

You should also avoid using expired Windex on delicate surfaces like wood or painted surfaces.
