remove super glue from lcd screen for sale
How bad is the glue on the LCD? This is not Dell recommended and this is way outside of scope (so I personally can only say from my experience but wouldn’t recommend trying without knowing the risks)…, but in my experience (90% +) Isopropyl Alcohol mixed 50/50 w/ distilled water and a microfiber cloth or even Q-Tip might work and I have used something like this on LCD screens (but unfortunately not on superglue, especially because of the way it might have bonded to the screen), even isopropyl wipes, but I do not know how well those will react with the glue. The acetone will typically work better... but the issue you run into is that it can react with the plastics/screen etc., and soften/damage/eat it etc. If you do decide to go that route be very careful with applying it to just the glue or if it’s a lot and you know you will get it on the screen maybe see if you can test a small spot… I haven’t been in chem recently so I am trying to remember some of this off the top of my head, but I think acetone would be more of a last ditch effort. I have also heard white vinegar mixed 50/50 with distilled might work as well, but again this is not something I have tried, and the results look to be something more likely on reg glue/gum etc vs superglue.

A high percentage concentration of Isopropyl Alcohol might work to soften up the glue enough to scrape it off with your fingernail, but you"ll need to leave it on the spot for awhile. I suggest using a Q-Tip soaked in 90% Isopropyl Alcohol to avoid exposing the TV screen itself to the alcohol as much as possible. Let it sit there for a minute or two, and then attempt to scrape it off while it"s still soft.
so…… you can try and use a dropper and get some alcohol in between the screen and digitizer. and let it sit for a while. the superglue will need to be softened by it for a while. do your best to keep the alcohol out of the screen.
heres a guide to acetone. since youre not using ACETONE on any real PCBs, YOU MIGHT be able to try it as a last ditch effort. both the alcohol and acetone will need to sit for a while so you should honestly go into this expecting some kind of permanent damage to either the digi, screen or both.
Knowing how to get super glue off glass surfaces helps, but so does selecting the right glue. Choosing a glue specifically formulated for glass will not only make your project a lot easier, but also allow for tidier, damage-free removal of any excess glue. With a bit of prevention beforehand, you can avoid a mess altogether.
Silicone-based glues can be great when working on glass jewelry repairs or crafts. Squeeze or clamp surfaces tightly to achieve a strong seal. Sometimes the glue will adhere better to the glass if the surface isn’t perfectly smooth.
For a glue that will work wonders with all your glass products, try Loctite Glass Glue: the super glue specially formulated for bonding glass. It is water-resistant, dries quickly and without clamping to form fast, durable joints. Plus, it is easily applied for everyday use.

All of the above will damage the screen. WD40 should never be used on any screen, regardless. The gorillas tape can"t remove what is on the screen, because the glue softened the polymer of the screen, mixes with it, then hardens...meaning it actually becomes part of the screen; the only way to remove that is to break it off, which is what you"ll do if you try the gorilla tapoe method. The citrus based goo removers, if which DSR is just one, will not work for the same reason. The glue has penetrated and dissolved the polymer resin of the screen, then hardened with it. It cannot be removed with a solvent, unless the screen it has integrated into is also removed.
Cyanoacrylate glue, also commonly known as Krazy Glue or super glue, is an instant adhesive that creates exceptionally strong polymer bonds between a variety of materials. Unlike other adhesives, cyanoacrylate (CA) glue does not require additional treatments to cure and harden to the surface of a material. Exposure to moisture or humidity in the air is sufficient to activate the bond between the active ingredient, ethyl cyanoacrylate, and the material. Anionic polymerization triggered by exposure to water molecules allows CA glue to create polymer chains that can bond to a range of materials, from wood and metal to ceramic, leather, and plastic.
While CA glue is chosen for its excellent bonding, this same property can be problematic when the glue adheres to an unwanted surface. Fortunately, there are a variety of methods to remove super glue from your skin, plastic, glass, fabric, and other surfaces.
When applying cyanoacrylates, it’s common to accidentally get some of them onto hands and hair. Since the skin produces moisture naturally, it is easy for super glue to bond quickly upon contact with your skin. To prevent CA glue from adhering to your fingers and hands, wear appropriate gloves and protective gear when applying the adhesive. In the case of an accident, you can easily remove super glue from skin on your hands and fingers using acetone or nail polish remover. For hair, lips, and other sensitive areas, peanut butter, margarine, and vegetable oil are substances that are also able to break the bond.
Cyanoacrylate adhesives can bond particularly well with plastic materials, and removing the glue can cause damage to the surface if not careful. To avoid damage to plastic materials, soak the area in a mixture of ammonia-free detergent and water. This can soften the bonds between the glue and the material’s surface enough for you to remove the glue without damaging the finish. If mild detergent doesn’t work, you can use nitromethane, a less harsh chemical solvent than acetone that will cause less damage than acetone, especially in the event that the surface is coated with paint or varnish.
Super glue adheres easily to glass, which can be particularly troubling when that glass is your eyeglasses, a window, or another delicate surface. For scratch-resistant glass surfaces, you can use solvents to loosen the glue and scrape the loosened glue off with a razor. However, more care must be taken with eyeglasses, which can be damaged more easily. In that case, use hot water, acetone, rubbing alcohol, and toothpaste, and other gentle solvents to gently remove the glue.
Getting superglue on your clothes can be especially frustrating, but it is typically easy to remove once it has hardened, depending on the fabric. Try scraping the glue off with a spoon or butter knife. If there is still hardened residue, spot check a section of the fabric to see if it is affected by acetone. If your spot check is successful, simply apply a small amount of acetone to the glue using a cotton ball or swab. This should loosen the glue sufficiently to allow you to remove it. Finally, you can apply some detergent or stain remover and wash the article of clothing to remove the remaining glue. If you are trying to remove the glue from a delicate fabric, it may be best to take it to the dry cleaner to avoid damaging it more.
Super glue bonds quickly and easily to metal, but it can easily be removed from metal surfaces using a solvent such as acetone, a scraping tool, and a hammer. Simply apply a small amount of solvent to break the adhesive bond, and then use the scraping tool to remove the softened adhesive. For large drops, you can use a hammer to loosen a dried cyanoacrylate spill by lightly tapping it.
Wood is extremely porous, which makes it easier for super glue to adhere, but also makes it harder to remove. Unlike metal, wood can become stained or discolored when exposed to solvents such as acetone. You can reduce the strength of your solvent by mixing it with water, but be sure to perform a spot test out of sight before applying the solvent to your wood surface. Use a cotton ball or swab to apply a small amount of solvent, and then use a scraping tool to lift the glue from the surface once it has begun to soften. Oils can also help to remove glue spilled on untreated wood surfaces.
