Removing Difficult Stains from Your Auto Glass

Your car gets exposed to stubborn outdoor dirt every day. At some point, you’ll notice stains on your auto glass which can be very difficult to remove. While DIY solutions may lighten the smear, they often aren’t enough to erase all of it.

However, not all car owners have the time and resources to seek professional removal. With that, we’ve compiled some of the experts’ advice when it comes to dealing with deep-seated dirt on auto glass.


If you just removed a decal, there’s a chance that some of it will stick on the glass. Although you can scrape this by hand, some of the adhesives may still linger. With this, you should soak it in soapy water first. Afterward, use a plastic scraper to remove the debris. Never use blades or metal scrapers since this might cause scratches. Wipe the glass with a lint-free towel once you’re done.

Window Tint

In the case of window tints, you need to use heat to get them off your auto glass. You have the option to use either a heat gun or a hair dryer to loosen up the window tint. Set the heat source at a high setting and point it two inches away from the glass. The edges of the tint should be easy to peel after this.

Always work in sections for a cleaner finish. If there is tint still lingering on the window, wipe it with WD-40 and a lint-free rag.

Spray paint

Did someone vandalize your auto glass? Spray paint might look like a big headache, but you can easily get rid of it. Using a plastic blade, scrape the layers of paint away from the glass. Make sure that you’re stroking the scraper in long and straight directions.

Once the majority of the paint is gone, apply acetone nail polish to the remaining spots. You can douche a microfiber fabric with the acetone and wipe it directly to the affected areas. Don’t forget to rinse your car with water after doing this.

Acid rain stains

Acid rain is known to cause expensive damages to cars. Also, it can leave hard-to-remove stains on the glass parts. To remove this, mix water and vinegar in equal parts. Apply the mixture using a microfiber towel then wipe it to the affected areas. Always wipe the glass clean each time you apply the vinegar and water solution. This is a cheap fix that works most of the time.

Tree sap

If you’re parking in an open area, there’s a chance that tree sap will fall on your auto glass. This stain can get really difficult to rinse off. But with the right cleaner, this should be a piece of cake. Apply diluted rubbing alcohol or a bug remover spray on the affected area then let it sit for a few minutes. Wipe it clean with a microfiber cloth afterward. Repeat the process until the tree sap stain is gone entirely.

Getting rid of stubborn stains doesn’t have to be expensive. There are some home remedies that you can use without ruining your car’s look.
