Remove Stickers from Glass & Windows: Easy Guide

Stickers can be found on various types of glass. What is the purpose of sticking them on? They are often decorative, but they can also serve as protection against external factors or function as a curtain to protect privacy.

Even if they were important to us at the time of application, old stickers do not look aesthetically pleasing, and most of us want to get rid of such unwanted decorations. Many people ask us: How to remove a sticker from a window? We have written a short guide on removing stickers from windows, which will be useful for parents and anyone who decorates windows with stickers.

Regardless of whether the sticker is on a window or door glass, car glass, furniture glass or mirror glass, we must be careful when removing it so as not to damage the glass. Even small scratches on the glass can cause limited visibility, light refraction, or look unsightly.

Types of glass

The type of glass is key when choosing a sticker removal method, as different types of glass have different resistance to damage and react differently to the chemicals used to dissolve adhesive residue. For example, car windows often have additional protective layers or are made of tempered glass, which can be more susceptible to scratching than standard window glass.

Soda glass panes

Soda glass is the most popular type of glass. It is primarily used for the production of everyday items, such as glasses, dishes, and glass packaging (bottles and jars). Soda glass is also used to produce window panes.

Other less common types of glass are: quartz glass, borosilicate glass, lead glass (crystal), optical glass, and sodium-potassium glass. Because they are similar to sodium glass in terms of hardness and resistance, they can be cleaned similarly.

Organic glass panes

It is also important to remember that most glass sticker removal methods do not apply to quartz glass panes, which are resistant to most chemicals. Removing stickers from acrylic glass and other glass products made based on organic chemical compounds is a separate topic.

In most cases, they react with organic solvents, such as acetone, and also with strong natural acids, including concentrated orange acid found in cleaning products, e.g., Orange Power from Planet Ark.

The most common places to apply stickers

• Window panes
• Car windows
• Mirrors
• Furniture glass
• Glass everyday objects (glasses, vases and other items)
• Packaging – bottles, jars and glass containers
• Other

What factors influence the effectiveness of removing stickers from windows?

• The material from which the sticker was made
• Type of glue
• Time from the moment of sticking
• How to remove

Window stickers are usually made of foil that is resistant to mechanical damage and weather conditions. These types of stickers are durable and sometimes difficult to peel off, and they can rarely be removed completely.

In the case of paper labels (e.g. jars, bottles), which are susceptible to moisture and are not very durable, peeling off the sticker is relatively easy. However, this does not mean that removing paper stickers is easy, especially when it comes to glue and paper residue. The adhesion of paper stickers and resistance to external factors depend mainly on the type of glue used.

How to remove a sticker from a window – popular methods.

• Temperature – heating the sticker
• Chemicals and organic solvents
• Strong detergents
• Water and other water-based products
• Cutting and grinding tools

In most cases, successful sticker removal will involve using two or more of the methods listed above.

Temperature – sticker heating

One of the most popular and safe methods for removing a sticker from glass is to use heat. The most popular tool is a hairdryer, which is available in almost every home.

Removing stickers with a hair dryer involves directing a stream of hot air at the sticker and heating the adhesive layer. The adhesive layer softens under the influence of temperature, which makes it much easier to peel off. After removing the sticker, use a cloth or paper towel to remove any remaining adhesive.

For this purpose, you can also use heaters (popular heat guns), but you should pay special attention to the safety of the person removing and the glass. These devices generate extremely high temperatures, which can cause the glass to crack.

Steamers, a device that generates steam, are an effective way to remove stickers. The high temperature of the steam effectively softens the glue, making it easier to remove the sticker.

Removing stickers from glass using a steam cleaner is an effective and quick method. They can be used for various types of stickers. Steam cleaners are very effective for removing paper stickers from glass and packaging.

How to remove a sticker from a car window?

The most common sticker on a car window is the registration sticker. You can remove it using one of the methods in our guide, or using a razor blade or other sharp tool. You should take care to remove any remaining glue and plastic using solvents or detergents.

Chemicals and organic solvents

Adhesives are used in popular stickers to attach them to various surfaces. The most commonly used types of adhesives are acrylic adhesives, which are highly waterproof and provide a quick and strong bond.

Epoxy adhesives are also popular because they are corrosion-resistant and provide excellent adhesion, typically operating within a temperature range of -40 to 80°C. Other types of adhesives used in adhesive labels are elastomeric and resin adhesives. Elastomeric adhesives are resistant to ageing and are easily removable, while resin adhesives offer resistance to chemicals and high temperatures.

To remove a sticker with acrylic glue, it is best to use paint removers, as they are the most effective in removing this type of glue. When it comes to epoxy glues, it is best to use acetone to remove stickers (Caution! Acetone has a very irritating smell).

White spirit

White spirit or other organic solvents will help soften or dissolve the glue. However, remember to use them carefully, as they can damage the surface from which you want to wash the glue residue. Before starting work, it is worth testing on an inconspicuous part of the material to make sure that the solvent will not cause discolouration or damage.

To effectively remove the glue, you can apply a small amount of gasoline to a cloth and gently rub the area with the glue. For difficult-to-remove residues, you can leave the solvent on the surface for a while to allow it to work. After removing the glue, it is a good idea to wipe the area with a clean, damp cloth to remove any remaining solvent.
Be sure to work in a well-ventilated area and wear protective gloves to avoid skin contact. In the case of strong fumes, it is also recommended to use a protective mask.

Acetone 

For example, you can use acetone-based nail polish remover, which is good at easily dissolving glue residue, but be careful not to use it too often so as not to damage the surface.
For stubborn glue residue, you can also consider using special glue removers available from DIY stores. However, it is always a good idea to test the product on an inconspicuous area to make sure it will not cause damage. Remember to always proceed with caution and use appropriate protective equipment, such as gloves, to protect your skin.

Isopropyl alcohol

Elastomeric adhesives can be removed easily using cleaning agents such as isopropyl alcohol. For resin adhesives, it is best to use detergents and washing liquids to remove the sticker effectively.

Removing the sticker with strong detergents

Strong detergents such as laundry detergent, dishwashing liquid, dishwasher cleaner, or induction cooktop cleaner can be effective ways to remove a sticker from your glass. First, mix the detergent with hot water to create a uniform mixture.

Then, use a cloth or glass brush to scrub the glass surface thoroughly. Be sure to use gentle movements to avoid damaging the glass. Finally, wash and rinse the glass thoroughly with detergent, then wipe it dry to remove any remaining detergent residue.

Cleaning products with salts and detergents (e.g. baking soda with detergent) can be used to remove stickers or price tags based on resin adhesives. Paint removers or vinegar can also be used to remove stickers from glass. However, it is essential to remember that these removal methods may not always be effective, depending on the type of adhesive used on the sticker.

Cutting and grinding tools

Cutting and abrasive tools, such as scrapers, utility knives, glass scrapers, razor blades, and other sharp objects, can effectively help remove stickers from glass.

Remember to wear safety glasses and gloves when using them. When working with a sharp tool, use gentle movements to help peel or scrape off the sticker by lightly cutting the adhesive layer. The sharp edge of the tool should be applied at a small angle to the surface of the glass to remove the adhesive and not cause scratches. This is especially important if you want to remove a registration sticker from your car’s window.

If necessary, you can try different types of tools to find an effective method to remove the sticker. Remember to wipe the surface thoroughly after each removal attempt. You can also use fine sandpaper to clean the surface. Finally, wash the glass with warm, soapy water, and wipe the surface dry with a cloth.

What should you pay special attention to when removing stickers?

Window frame protection.

When removing stickers from a window, door or furniture glass, remember to secure the window frame or other object properly. They may not be resistant to solvents.
