The chemical formula of this cleaner is Isopropyl alcohol. Water, Ammonia (NH3), Ethanol (C2H5OH), Alpha-Terpineol, D-Limonene, and a few other ingredients are in much smaller quantities.

The exact amounts of these ingredients are not listed. It has about as many chemicals as other household cleaning products like Lysol or Comet.

It is used in many ways that including metal can cleaner, glass bottle cleaner, window cleaner,  countertop cleaner, multi-surface cleaner, and many more.

Despite its popularity and reputation as a multipurpose cleaning product, there have been questions about whether or not Windex is actually flammable. Let’s take a look at what we know about these burning questions…

Is Windex Flammable?

First, it’s important to note that the current formula includes isopropyl alcohol and acetone (the two main ingredients in Windex)and both have flashpoints. This means they can cause fires when exposed to flames, sparks, or very high heat.

Most commercial glass cleaners cleaning products containing these chemicals are labeled as flammable because of this risk.

However, the manufacturer company of Windex claims that it is not flammable and isn’t going to spontaneously combust into a fireball on its own because of how diluted it is with water.

Reasons Why Windex is not Flammable

Windex is a solvent. Solvents are chemicals that dissolve other materials. Because of its solvency, it will not burn like dry combustibles.

Still, it can be ignited by an ignition source or a strong electrical spark in an oxygen-rich environment. Some common examples of solvents are alcohol, acetone, and kerosene.

These types of chemicals give off fumes as they evaporate, which are very flammable. The fumes from Windex should be considered hazardous;

However, this does not pose a fire hazard if you follow safety precautions when using it because of how diluted it is with water.

Is there any flashpoint of Windex?

In order to understand what makes a chemical flammable, it’s important to understand what flashpoint is. As per the manufacturer’s Safety Data Sheet, the term flashpoint is not applicable for Windex because of the product type.

The flashpoint of a liquid describes its minimum temperature at which vapors will ignite within a certain percentage of concentration in air.

Liquids with a high flashpoint are safer to use and handle because they can be heated to very high temperatures before igniting (and catching fire).

As Windex hasn’t any flashpoint and autoignition temperature, it is completely safe for all kinds of uses. There is no fire hazard.

Is Windex safe for my children and pets?

Windex is safe for all household surfaces. However, if you are not sure about the safety of Windex, then you can always test it on a small area first to check whether it will be harmful or not.

If your children and pets use Windex, there is no need to worry because Windex does not contain any toxic ingredients that may harm them in any way.

Also, the fumes released during cleaning are very mild and non-toxic too. The components used in this product are completely safe for humans as well as animals, so I suggest using them without worries!

Why is Windex liquid at room temperature?

The reason Windex is liquid at room temperature is that it is a non-polar solvent. Non-polar solvents are those that dissolve both polar and nonpolar substances.

Polar substances are those that have a strong electric charge, such as water and oil. Non-polar substances don’t have a strong electric charge, which is why they can dissolve in polar substances.

Safety precautions while using Windex

Even if you’re pretty certain that Windex is nonflammable, it’s always best to play it safe.

  • First, avoid using it near an open flame or another heat source. It might not be as flammable as rubbing alcohol, but it could still ignite—and might isn’t good enough when a fire is involved.
  • Second, use protective equipment (like gloves and eye protection) when cleaning with that cleaner.
  • And finally, remember that alcohol, in general, can cause drying of skin and eyes; if used often or in high concentrations, Windex can also irritate your skin. So, even if you follow all these steps, don’t overdo it!

Cleaning products are meant to make our lives easier and more comfortable. If there are any signs of irritation after using Windex for any length of time, stop immediately and try another method.

  • Do not mix it with other household cleaners or chemicals; You can use alcohol glass cleaner or ammonia cleaners instead if this quite expensive cleaners.
  • Follow all directions written on bottles and containers when mixing chemicals together.
