Superglue is suitable for many home improvement and handicrafts. Unfortunately, it's all too easy for the glue to get into places it should not. Or maybe bonded workpieces should be detached from each other. Superglue can be removed with these tips.
For many do-it-yourselfers and crafts superglue is a popular material. In a matter of seconds, different materials can be permanently bonded together. Superglue or Superglue are based on the substance cyanoacrylate. This substance reacts with humidity and is dried and cured after a few minutes. When crafting or DIY, superglue can get into unwanted places on objects, clothing or skin. For the different surfaces, such as wood, metal, stone, glass, ceramic, paint, plastic, textiles and skin, there are various ways to remove the superglue again.
The cyanoacrylate material contained in the superglue quickly combines with moisture from normal indoor air. Thus, the drying and curing process begins immediately after the adhesive exits the tube. Within a few minutes the superglue has hardened. A full cure is achieved after about two hours . If superglue has landed on an unintended surface, it should be removed as soon as possible . Best possible is the distance before the full degree of cure is achieved, since within this time, the edge areas of the bond still easiest to dissolve. But even with complete curing, the superglue can be removed again. Unfortunately, this is associated with a little more effort.

Second Adhesive Remover
Various super glue removers are commercially available from well-known brand name manufacturers as well as so-called "no-name" products in various price categories. The exact ingredients are barely listed. When using a remover for superglue from the trade, the instructions that are usually on the packaging should be read very carefully. Only removers should be used for each designated material. It is also very useful to test the remover in a smaller, less visible place before larger areas or highly visible areas are processed with the super glue remover.
In the worst case, it can lead to delamination on the surface, such as wood or paints, which can then leave unsightly marks. For example, with wood surfaces, rubbing marks with brighter discolorations or painted surfaces may show through the background material. On smooth surfaces, such as glass or metal, the commercial superglue remover can be used easily.
On textile surfaces, these removers are often not suitable at all and even when used on the skin with this remover should be handled with great care, as they may have very unhealthy chemical compounds.
Tips: Before using a commercial superglue remover, the instructions for use should be read very carefully! Only use on the skin if the packaging is expressly described as suitable. The superglue remover should not be advised or used near the face, especially the mouth, eyes and nose. In less visible areas of the surfaces to be treated, a test should be performed.
On smooth surfaces, such as glass, metal or smooth polished stone tiles, superglue can be easily scraped off after curing. Appropriate tools for this, such as a glass spatula, can be bought at any hardware store. On textiles or on the skin, mechanical scraping off of superglue is not possible. On surfaces made of wood, lacquer or plastic, attempts to leave the super glue with a spatula or similar scratches and unsightly marks.
Tips: Care should be taken when scraping off the superglue. No excessive pressure should be exerted on the surface to be worked on, as the spatula or the working tool could otherwise scratch, scrape or groove in the substrate. Knives should not be used to scrape off superglue due to the risk of injury and the slight leaving of unsightly scratches. The scraper should be as flat as possible when scraping off the superglue to avoid deep scratches on the surface.
Remove by heat
The cured adhesive layer of the superglue can be dissolved by the supply of high heat. For this purpose, either a Heißluftföhn or a hot air gun for craftsmen. The hot air gun has the advantage that the hot air can be guided very precisely to the glued areas. When working with the hot air blower or the hot air gun, you should first try to loosen the edges of the bonded areas . Often, the remaining adhesive layer can then be peeled off mechanically by hand or a spatula.
Removing superglue with a hot air blower or hot air gun is not equally good for all surfaces or should be used with great care. For example, the lacquers on lacquered surfaces could also be replaced. Plastic or plastic surfaces could be deformed by the hot air. When working with the heat gun, very high temperatures can occur. If the heat is continuously fixed to a point, burns may occur on the surface, such as on wooden surfaces . The consequence of this is then unsightly dark to black discoloration.
Tip: The heat should be applied to the bonds only at short intervals so that the processed area does not overheat and can cool down between intervals.
Remove with solvent acetone
Simple means for dissolving adhesive residues of superglue are acetone or 2-butanone .
Acetone is contained in solvents that can be bought in hardware stores. Acetone or 2-butanone are often also constituents of the commercially available superglue remover. Furthermore, acetone is also contained in nail polish remover or can be obtained in pharmacies in small quantities. The removal of adhesive residues of the superglue with acetone or 2-butanone is particularly well possible on surfaces of glass, stone, ceramic and uncoated metal . Even textiles can be treated well with acetone. Here, the superglue can be removed by stronger rubbing after a certain exposure time of the acetone from the fabric fibers. Then the textiles should be washed in the washing machine.
Small amounts of nail polish remover are available in almost every household or can otherwise be quickly bought in any drugstore. The acetone can be used on almost all surfaces. For plastic objects, acetone is too aggressive and on painted surfaces it acts as a solvent, or can dissolve the paint with. Since acetone is a flammable material and also emits vapors, working with acetone or nail polish remover should be done carefully and in well-ventilated areas. For 2-butanone, it is also considered that it is a flammable substance and can give off harmful vapors. These vapors should not be inhaled directly, and both acetone and 2-butanone should not come near the face, especially the eyes, nose and mouth. 2-butanone can be obtained as a solvent in pharmacies or online shops for craftsmen's needs.
Remove with oil, water, detergent
If superglue has landed on garments or other textiles, it can be removed with creeping oil (edible oil) and a water bath with detergent or soapy water. The oil should be applied to the affected areas and rubbed in for a while. Thereafter, the oil should act on the stain for a longer period of time. The oil softens the superglue and can be mechanically scraped off with a scraper or similar. Subsequently, the garment should be washed several times by hand in a warm water bath with detergents, dishwashing liquid or soapy water. If there are still traces of glue left in the fibers, another pass with application of oil and subsequent washing may help to clean clothes or other textiles. Carpet can be treated in a similar way to remove superglue that has flowed onto the carpet. The fibers of the carpet can then be cleaned by light dabbing and rubbing.
If no oil is available, it can be tried only once with a water bath . The clothing or other textiles should then be soaked in a water bath at least 60 to 80 ° C hot. The hot water bath can soften and dissolve the dried out spots. These can then be removed mechanically, for example, from clothing. In the water bath but should always be an additive of detergent or soapy water, since pure water reacts with the cyanoacrylate and binds the superglue.
Tip: With textiles or garments, however, it must be ensured that not all fabrics and materials can withstand such high temperatures without causing damage, such as wool, silk, viscose and others.
For dear or precious garments, the removal of the glue residue should be left to a chemical cleaning company. The cleaning companies have a great deal of experience in removing adhesives. Cleaning service providers can also be commissioned for cleaning carpets or, if adhesive has been used on upholstered furniture. In this case, however, relatively high costs can arise. These would have to be requested in individual cases from the respective cleaning company.
Removing by cold
As well as heat, even great cold below freezing can be helpful in removing superglue. For example, contaminated fabrics or other bonded items may be placed in the freezer compartment of the refrigerator or in the freezer for a few hours. Freezing will make the instant glue brittle or simply bounce off as the rest of the material contracts due to the cold. The superglue can then be removed mechanically from the fabric or other material from articles by peeling, scraping, scraping or vigorously rubbing. After removal of the top adhesive layers, the garment or fabric pieces should be washed in a warm water bath with soapy water or in the washing machine to remove the remaining impurities from the fibers through the superglue.
Of course, the superglue can be removed using cold air only for items that fit in the freezer or in the freezer in this way.
Tip: In the pharmacy there is cold spray, which is usually used in the medical field for injuries for pain relief or for outpatient anesthesia. With the help of this cold spraying with prolonged spraying, the spots soiled by the glue, the superglue can become brittle or jump off. The residues can then be easily removed again by rubbing or scraping.
However, when using superglue on the skin, the cold spray should not be used as it could cause frostbite and serious injury in the underlying skin layers. The cold spray should only be used with great care and in well-ventilated areas. It is also not suitable for all materials and can act as a solvent on painted surfaces, for example. Even with plastic objects, the cold spray can not be used.
Remove super glue from the skin
Sticking on the skin with superglue can be very uncomfortable or painful. When removing the adhesive layers, care should be taken to avoid further damage or injury. So should be dispensed with mechanical effects, such as strong rubbing or scratching. This could further injure deeper skin layers. The most gentle way to remove superglue from the skin is to soak the affected area over a longer period in a warm water bath with soapy water and gently massage until the adhesive dissolves. Another option is to dab the affected skin very gently with a little nail polish remover and release the top adhesive layer. The nail polish remover should, however, be used very sparingly, since it is not a very healthy solvent for the skin and it could also lead to redness or rashes on sensitive skin. Removing the glue with edible oil and then washing the skin area with warm soapy water may also be helpful. In most cases, the superglue can not completely dissolve away from the skin as it also penetrates into the fine pores of the skin and hardens quickly.
After removing the upper adhesive layers, the skin should be provided with a cream, as it remains elastic and gives a more pleasant skin feel. The acetone in the nail polish remover dries out the skin. Also for this reason, the affected skin should be well treated with a cream or Vaseline. After one to two days, the skin's natural sweat and ability to regenerate ensure that the remainder of the superglue will repel itself. If larger areas of the skin or very sensitive areas of the skin, such as mucous membranes in the face with superglue on the eyes, nose or mouth, or even children are affected, then perhaps medical advice and help should be consulted.
