How to Remove Spray Paint from Glass

Painting can be fun until you accidentally spray something you didn’t intend to. This can happen to anyone, whether it’s your first time or you’ve been painting for a long time. But not to worry, removing the paint is not an impossible task! 

Even though most spray paint is permanent on glass, you can still get it off. There are many ways to do this, depending on how wet or dry the paint is and the kind of glass you’re dealing with. In this article, we will look at over 8 methods for removing paint from glass items.

Is it Hard To Get Paint Off of Glass?

It depends on the type of paint and how long it has been on the glass piece. Most paints can be easily washed off from glass and other surfaces when they are still wet.

On the other hand, dried paint can be difficult to remove, especially if it’s acrylic and is specifically made for the glass material. Such paints are usually permanent and cannot simply be washed away with water and soap once they are dry.

You will need some kind of solvent or product and maybe some elbow grease to get rid of the paint. There are many ways to achieve this, as you will soon discover in later sections.

Why is Spray Paint Hard to Remove From Glass Surfaces?

As earlier indicated, spray paint can be hard to remove from glass, especially if it’s hardened. But why is this so?

Spray Paint Is Permanent

Most spray paints are meant to be permanent. This is usually the case if you’re using a specialized product for that type of glass. So, once the paint gets on the glass surface, it becomes hard to remove.

Spray Paint Is Fast-drying

Spray paint is fast-drying; it dries much faster than regular paint. This means if you mistakenly get it on an object, there will be little or no time to wipe it off. It happens that the best time to wipe off any paint is when it’s still wet; with spray paint, you may not even notice on time.

Water Is Not Enough

Removing dried spray paint with just water is usually hard or even impossible, whether the paint is water-based or oil-based. Water-based paints harden as they dry, while oil-based paints will not dissolve in any liquid except solvents, which is understandable since they are made of oil. Oil and water don’t mix!

Scrapers Can Damage Your Glass

Even if you decide to use a scraper (especially when dealing with old paint), there’s always a chance you could scratch the glass below.

Thus the best way of getting spray paint off glass is to use solvents like alcohol, vinegar, turpentine, and mineral spirits. You can also invest in commercial spray paint remover for glass.

How to Remove Spray Paint From Glass

How you get spray paint off glass depends on the paint type and what kind of glass you have. In the following sections, we discuss various methods for cleaning paint-stained glass using different materials and solvents.

How to Remove Spray Paint From Glass With Alcohol

Alcohol is a great way to remove spray paint from glass if you prefer a homemade solution. There are essentially two types of alcohol you can use – rubbing alcohol and denatured alcohol. Although denatured alcohol is much stronger, it can damage glass and should only be considered if rubbing alcohol doesn’t work. In this case, you should test a hidden area before you proceed.

Rubbing alcohol is usually preferred as it’s safer for glass, but it needs to be at least 70% concentrated for it to be effective. The higher the concentration, the better! 

The method for removing spray paint from glass with rubbing alcohol is pretty straightforward.

• Soak a piece of dry microfiber cloth in rubbing alcohol and press it against the glass surface with paint.
• Hold it down for a few minutes until the paint begins to soften.
• Then scrub vigorously to remove the remaining paint residue.

• Once the paint is off, wash the glass with soapy water and wipe it dry with a piece of cloth.

Besides glass, rubbing alcohol can also be used to clean spray paint on plastic surfaces. 

How to Remove Spray Paint From Glass With Vinegar 

White vinegar is another homemade solution you can use to remove spray paint from glass. However, it does require a bit of elbow grease. Vinegar is commonly used as a cleaner; it contains acid that effectively dissolves stains, grease, paint, and even mineral deposits. Besides glass, it can be used to clean paintbrushes.

The method for using vinegar to clean paint on glass is described below:

• Pour white vinegar into a measuring cup such as Pyrex, then put it in the microwave to boil for about 4 minutes. You can also use a stovetop.
• Then take it out with gloves or oven mitts.
• Next, dip a clean towel or rag into the hot vinegar, then press it against the stain for 2-4 minutes. This will soften the paint. Then using the same rag, scrub the area thoroughly.

• Dip a microfiber cloth in warm soapy water. Use it to wash the glass. Then wipe dry with a paper towel.

Besides glass, vinegar also works on metal, wood, and even fiberglass.

How to Remove Spray Paint From Glass With Turpentine

Also known as white spirits, turpentine is commonly used as a paint thinner due to its non-sticky nature, less odor, and low price. You can also use it to remove fresh paint from glass.

The process is straightforward:

• Dampen a clean piece or rag or cotton ball with turpentine.
• Gently press down on the paint spots and wait for a few minutes as it loosens the stain.
• Next, scrub the area with the cotton ball.

• Then wash off the paint residue with warm soapy water and wipe dry with a clean rag or paper towel.

How to Remove Spray Paint From Glass With Mineral Spirits

Mineral spirits is another petroleum distillate that works like turpentine. However, while mineral spirits will only remove fresh paint, turpentine can also dissolve slightly dried paint. The process for using mineral spirits is pretty much the same as turpentine, except that you’re replacing turpentine with mineral spirits. Also, use a microfiber cloth instead of a rag or cotton ball.

How to Remove Spray Paint From Glass With Acetone 

Acetone is another effective solvent that gets spray paint off regular glass, such as mirrors and untreated mirrors. For the best results, use acetone with a purity of at least 70 percent. If you can get something with a higher percentage, good for you.

The steps are as follows:

• Soak a clean rag with acetone.
• Then place the rag on the paint spot. Hold it down for a few minutes to loosen the paint.
• Then scrub the stain with the rag.
• Soak a microfiber cloth in warm soapy water and use it to wipe any paint residue or acetone.

• Use a clean rag or paper towel to wipe it dry. 

How to Remove Spray Paint From Glass With Razor

For tough hardened paint, you can use a sharp razor to scrap the area. This should be done before applying solvent, or you can use the razor alone. You must be careful in order not to scratch the glass. 

The steps are as follows:

• Start by cleaning the paint spots with warm soapy water. This will help lubricate the area and reduce the risk of scratching the glass with your razor blade. 

• Hold the razor blade at an angle of 45 degrees and gently scrape the paint. 

• Try to push firmly but don’t apply too much pressure, so you don’t end up chipping the glass. 

• Start by cleaning the paint spots with warm soapy water. This will help lubricate the area and reduce the risk of scratching the glass with your razor blade.
• Hold the razor blade at an angle of 45 degrees and gently scrape the pint.
• try to push firmly but don’t apply too much pressure, so you don’t end up chipping the glass.

• After that, wash off the paint residue with soapy water. Then dry it.

How to Remove Spray Paint From Glass Mirror

Any of the solvents mentioned above would suffice to remove spray paint from the glass mirror. These include vinegar, rubbing alcohol, nail polish remover, or other acetone products. The steps for using each of these products are described above. Another item you could use is fine steel wool. Steel wool is not only great for mirrors but other small items like glass jars. We’ve also outlined the steps for using fine steel wool in the next section.

How to Remove Spray Paint From Glass Jars

Without using any harmful chemicals, one of the best ways to remove spray paint from glass jars is with fine steel wool or a scouring pad. 

These items (i.e., scouring pad and fine steel wool) are well-suited for small glass craft objects like vases, bowls, and jars. The good thing about them is that they are gentle on the glass surface and barely leave any marks if you follow the right steps. 

• Start by lubricating the paint spots with oil or warm soapy water. This helps to prevent scrateches when eventually use steel wool or a scouring pad.
• Next, gently scrub with steel wool or a scouring pad until you get the paint marks to come off.
• Once the paint is off, wash of any paint residue with soapy water.

• Then dry with a clean cloth or paper towel. 

How to Remove Spray Paint From Glass Window

To remove spray paint from glass windows, you can either use vinegar or a pressure washer. The method for using vinegar is already described above. Just soak a clean rag in hot vinegar and use it to dissolve the dried paint. Vinegar doesn’t only work on glass but other surfaces, including wood and fiberglass.

Another method is to use a pressure washer. This method is particularly recommended if you’re cleaning the outside of the window. It is not only safe but also convenient.

The process is pretty straightforward. Start the pressure washer but set the water at low pressure to avoid breaking the glass. Once you adjust the nozzle to the right pressure, direct it to the window and spray at an angle of 35-45 degrees. Move it around and continue to spray until the paint starts peeling off.

How to Remove Frosted Spray Paint From Glass

To remove spray paint from frosted glass, you can either use acetone or a natural glass cleaner like Windex.

The procedure for using acetone is described above. You can opt for any of these products – paint thinner, nail polish remover, lacquer thinner, or any other acetone product. Just soak a rag with the solvent and use it to daub the paint off.

If you prefer to use Windex or any other glass cleaner, spray it on the paint spots. Then gently scrape the paint residue with a small razor blade. Hold the blade at an angle of 45 degrees so you don’t end up scraping the glass.

Finally, rinse the paint and wipe the area with a paper towel.

How to Remove Spray Paint From Glass Without Chemicals

If you prefer not to use chemicals, there are other ways you can remove spray paint from glass. You can use steel wool or a window scraper, or you can use a natural cleaner like vinegar.

The process for using steel wool is the same as described above. Lubricate the glass item with olive oil or dish soap and water. This helps to prevent scratches and keeps the paint from flaking off.

Next, gently scrub the paint spots with your steel wool or window scraper to get the paint off. Then wash the area with soapy water and dry with paper towels.

We suggest doing the project over a disposable plastic container in order to catch the falling paint chips. Fill the container with warm soapy water before removing the paint. Once you’re done with the project, remove the container and place it in a safe location and wait for the water to evaporate before discarding it according to your local guidelines.

If you prefer using vinegar, follow the steps described in earlier sections. The acid in vinegar doesn’t only dissolve paint on glass but also works on metal, wood, and even fiberglass. You can also use vinegar to clean your paintbrush.

How to Prevent Overspray When Spray Painting Glass Surfaces?

Why learn how to remove spray paint on glass when it can be avoided? Follow the tips below to prevent paint overspray when working on glass or some other material:

• If you are painting outside, make sure the breeze is not too much. Strong wind gust is one of the major causes of paint overspray.
• Cover or tape off any area you don’t want to paint. If you don’t have masking tape, use old newspapers, cardboard, or cloth (es).
• If you decide to use a sprayer for smaller surfaces, we recommend using an airless sprayer or HVLP. This will help minimize overspray, especially if you set the sprayer to the low pressure and build up from there.
• If you’re using a paint gun, make sure it us the right nozzle size.
• When spraying, keep the aerosol can at a fair distance (6 to 10 inches) from the surface. Spraying too close can cause bubbles and crackles, while spraying too far will cause the paint to get on surrounding areas or items.

• To prevent clogging of the nozzle, shake the spray can for a few minutes before use and shake it frequently while using it. This may not apply to every product. Make sure to check the label.
