How do I remove glue from a plastic part?

To remove glue from a plastic part, here are some effective methods you can try:

File it: Use a fine abrasive file to scrape the glue off the model.

Freezing: If the plastic part is small enough, you can try freezing it for a couple of hours. The cold temperature can cause the glue to become brittle and flake off more easily. Be careful not to leave it in the freezer for too long, as some plastics may become brittle and crack.

Heat: For some glues, applying gentle heat can help soften the adhesive and make it easier to remove. Use a hairdryer or heat gun on a low setting and wave it over the glued area. Be cautious not to overheat the plastic, as it may warp or melt.

Solvents: Use a solvent-based adhesive remover or nail polish remover containing acetone. Apply it to the glued area and let it sit for a few minutes to soften the glue. Then, use a plastic scraper or an old toothbrush to gently scrub off the glue residue. Be careful as some plastics may react to the solvent and melt. Always test on a piece of scrap first.

Vegetable or mineral oil: These oils can sometimes help dissolve and loosen up glue residue. Soak a cloth in the oil and press it onto the glued area for a while, then try scraping off the softened glue.

Commercial adhesive removers: Look for products specifically designed for removing adhesives from plastics, such as those used in the automotive industry. Follow the instructions carefully and test on a small, inconspicuous area first to ensure the product won't damage the plastic.

Regardless of the method you choose, be patient and take your time. It may require some elbow grease to fully remove stubborn glue from plastic surfaces. Additionally, always spot-test the removal method on a small, inconspicuous area first to ensure it won't damage or discolour the plastic.
