- Gently dab the glue spot, allowing the acetone to soften the adhesive for several minutes.
- Carefully peel or rub the softened glue away using a plastic scraper or fingernail.
- Repeat as needed, avoiding excessive acetone exposure.
- Clean the area afterward with mild soap and water to remove residue.
Using Isopropyl Alcohol
Isopropyl alcohol (rubbing alcohol) is less aggressive than acetone and can be effective on small glue spots or residues.
- Apply isopropyl alcohol (70% or higher) to the glue using a cotton ball or cloth.
- Let it sit for several minutes to penetrate the adhesive.
- Gently rub the glue to loosen it.
- Repeat the process until the glue is removed.
- This method is safer for plastics sensitive to acetone.
Soaking in Warm Soapy Water
For delicate plastics or thin glue layers, soaking in warm soapy water can help soften the adhesive.
- Fill a container with warm water and add a few drops of mild dish soap.
- Submerge the glued plastic piece for 15 to 30 minutes.
- After soaking, gently rub or scrape the glue using a soft cloth or plastic tool.
- This method is safe but may require patience and multiple attempts.
Using Commercial Adhesive Removers
There are commercial products specifically formulated to dissolve super glue safely on plastics.
