Will Windex Hurt Car Paint? 

Applying Windex to car paint hurts it because it is too harsh. When you clean your mirrors, you may notice the removal of dirt and grime with a streak-free shine, but Windex will eventually strip away the finish when used on a car paint surface.

What Does Windex Do to Car Paint?

Household cleaners like Windex contain harsh and powerful chemicals that are typically too abrasive for paint. It may seem like a car would be as durable as glass, but the paint is not. Windex is abrasive enough to clear the coat, fade the paint, cause corrosion, discoloration, and more.

Like most car owners, you’ll want to go the extra mile to protect your car’s exterior by using products that were made to clean the paint without damaging it. Unfortunately, Windex is not included in that list.

  • 2-Hexoxyethanol
  • Isopropanolamine
  • Ammonium Hydroxide
  • Lauryl Dimethyl Amine Oxide

Can You Use Ammonia-free Windex on Car Paint?

Before you add the Ammonia-free version of Windex to your cart, beware! The Ammonia-free version is still linked to strong fumes that will irritate vehicle paint. However, you may not see the damage immediately as the paintwork will dry and chip over time.

However, you can use it on certain parts of your vehicle. The Windex parent company SC Johnson recommends using Windex® Ammonia-Free Glass Cleaner in the following areas:

  • Car windows
  • Glass/Mirrors
  • Chrome
  • Stainless steel
  • Plastic
  • Vinyl surfaces

Is It Okay To Use Windex on Car Paint Once?

It’s a warm sunny day, and you decide on a whim to skip the luxury car wash station and quickly clean your car yourself before you hit the road. The only product you have on hand is Windex. You must consider if using this product once will cause permanent damage.

Glass cleaners like Windex strip the paint on your car and may even dull the finish. Although the damage will only be minimal if you use it once, it’s not a good idea to use it regularly.

Unfortunately, many car owners use whatever they find around the house to clean their cars, which hurts more than it helps. Therefore, it is necessary to purchase cleaners specifically made for vehicles and safe for car paint to have on hand for these instances.

Is Windex Safe on Car Interiors?
