If gentler methods don't work, try more powerful chemical solvents, such as lighter fluid, paint thinner, acetone, or rubbing alcohol.
Acetone: Acetone is a common solvent that can soften some types of adhesives, including some epoxy formulations. Soak a cloth in acetone and apply it to the glued area. Let it sit for a while before attempting to scrape the glue off.
Try softening the glue first with a household all-purpose cleaner. For a tougher alternative to acetone, experiment with denatured alcohol, lighter fluid, or hydrogen peroxide. Apply with a rag or cotton ball, hold to dissolve the glue, then wipe away.
WD-40 can also loosen the hold of strong adhesives such as super glue. So, if you drop some glue on the floor or bench, spray a little WD-40. In no time you'll be able to wipe the glob right of your bench surface.
Acetone can remove hardened glue by weakening the molecular bonds in the polymers. To remove glue from glass and porcelain, wait for the glue to dry and then use a cotton ball to dab acetone onto the affected area. Once the glue has dissolved, simply wipe or scrape it away.
If gentler methods don't work, try more powerful chemical solvents, such as lighter fluid, paint thinner, acetone, or rubbing alcohol. Some of these solvents can affect wood finishes and paint, so test first and apply with caution. Rub the solvent in gently for a few minutes, then wash thoroughly with a damp cloth.
Blot the glue with acetone or rubbing alcohol and let this substance break down the glue. Clear away with a damp cloth. For fabric: Use acetone, but test sparingly first to avoid potential damage. Once the adhesive bond has begun to break, apply a pretreatment stain remover deep into the glue.
White vinegar is a safe and natural cleaner, deodorizer, and adhesive remover you can use on many surfaces. Soak a paper towel in vinegar and cover the sticky spot.
Apply Heat
Some stubborn adhesives melt or soften and become much easier to remove when heated. Heat the adhesive using a heat gun. If you do not have access to a heat gun, a hair dryer may work in a pinch. Once the surface is hot, try to gently scrape the adhesive away using a putty knife.
Soak the glue residue in rubbing alcohol, acetone, or vinegar. Leave it soaked for a few minutes then try scraping it off again. If the glue still proves too stubborn, try heating it up with a hair dryer. This should help loosen up the glue.
Another versatile household product is baking soda. When making a paste of baking soda and water, its abrasive properties can work wonders on stubborn adhesives. This solution is especially useful on non-delicate surfaces like plastic and metal.
Try acetone
Google says that acetone, alcohol, or paint thinner will dissolve Gorilla Glue. It may need to soak for a while to get into the joint.
Submerge dried out glue into a bowl of boiling water to revive it. If your Elmer's glue or craft glue is dried out, try heating it up. Heat will soften the glue, potentially reviving it enough to satisfy your needs.
Use a cotton ball soaked in pure acetone or nail varnish remover, and press it against the glue. Once it's dissolved, it should be easy to wipe away. Alternatively, try scraping away the glue. Use a putty knife or razor blade.
You've probably been using Windex Glass and Window Cleaner for years, as have your parents before you. Designed, as the name implies, for streak-free cleaning of glass, there are many other ways you can use Windex around the home. One way to use this spray cleaner is to remove stubbornly sticky glue residue from glass.
Dab a clean rag or soft cloth in acetone (commonly found in nail polish remover) to remove excess glue from metal. Mineral spirits are an alternative to acetone. Wipe excess. Use another clean cloth or rag to wipe any excess acetone or mineral spirits from the metal.
Acetone is a solvent that breaks down super glue. So, try applying acetone or nail polish remover that contains acetone to the affected area. This should help dissolve the super glue. You should then be able to gently peel or roll the glue off.
Hydrogen peroxide has also been used as an adjunct solvent to aid the removal of solidified superglue mass, but this, too, comes with the risk of local tissue irritation, given its corrosive properties [16].
You can remove glue residue with a glue dissolving solvent or homemade glue remover, such as cooking oil, rubbing alcohol (isopropyl) or acetone (nail varnish remover).
