Gorilla Glue is incredibly strong, which is its main selling point. However, this strength can become a problem if you accidentally glue something you didn't intend to, or if you need to separate glued items later. Removing Gorilla Glue can be challenging, but it's not impossible. This guide provides various methods, tips, and precautions to help you successfully remove Gorilla Glue from a variety of surfaces. Remember safety first; always wear appropriate protective gear like gloves and eye protection.
Understanding Gorilla Glue and its Properties
Gorilla Glue is a polyurethane-based adhesive, meaning it expands as it cures. This expansion creates an extremely strong bond. The chemical reaction involved makes it difficult to dissolve with simple solvents like water or soap. Understanding this is key to choosing the right removal method. Different surfaces require different approaches, as some methods might damage delicate materials.
Types of Gorilla Glue
It's important to note that there are different types of Gorilla Glue, including:
- Original Gorilla Glue: This is the classic formula, known for its extreme strength and expansion.
- Gorilla Super Glue: This is a cyanoacrylate-based adhesive, faster-setting and easier to remove than polyurethane-based Gorilla Glue. (The removal methods in this article primarily focus on the polyurethane-based Gorilla Glue).
- Gorilla Wood Glue: This is a PVA-based adhesive, significantly easier to remove than the polyurethane version.
Methods for Removing Gorilla Glue
The best method for removing Gorilla Glue depends on the surface it's stuck to. There's no one-size-fits-all solution. Here are some common techniques:
1. Isopropyl Alcohol (Rubbing Alcohol)
This is a good starting point for many surfaces, especially non-porous materials like glass, metal, and some plastics.
- How to: Soak a cotton ball or cloth in high-concentration isopropyl alcohol (90% or higher). Gently apply to the glued area, allowing the alcohol to penetrate the glue. Let it sit for a few minutes, then gently try to scrape or peel away the softened glue. Repeat as needed.
- Caution: Test on an inconspicuous area first to ensure it doesn't damage the surface. Some plastics can be weakened by alcohol.
2. Acetone (Nail Polish Remover)
Acetone is a stronger solvent than isopropyl alcohol and can be effective on tougher glue bonds. It’s particularly helpful for removing Gorilla Glue from hard surfaces.
- How to: Apply acetone to a cotton ball or cloth and gently rub the affected area. Be patient and allow the acetone to work. Scrape away the softened glue with a plastic scraper or dull knife.
- Caution: Acetone is highly flammable and can damage some surfaces, including painted surfaces and plastics. Always work in a well-ventilated area. Test in an inconspicuous area first.
3. Heat
Heat can soften Gorilla Glue, making it easier to remove. This method is suitable for various materials, but be careful not to damage the surface with excessive heat.
- How to: Use a hairdryer on a low setting to gently warm the glued area. A heat gun can also be used, but requires extreme caution to avoid burning or damaging the surface. Once the glue is softened, use a scraper or putty knife to remove it.
- Caution: Monitor the temperature closely to prevent damage. Excessive heat can warp or melt certain materials.
4. Mechanical Removal
For stubborn glue, you may need to resort to mechanical removal.
- How to: Use a sharp scraper, putty knife, or even a chisel (for very stubborn glue and appropriate surfaces) to carefully chip away at the glue. Be patient and work slowly to avoid damaging the underlying surface. This method is best for strong, durable surfaces like wood.
- Caution: This method carries a risk of scratching or damaging the surface, so use caution and consider the material's durability.
5. Commercial Glue Removers
Several commercial glue removers are specifically designed to dissolve polyurethane-based adhesives. These products can be more effective than home remedies, but always follow the manufacturer's instructions carefully. Test on a small inconspicuous area before full application.
Removing Gorilla Glue from Specific Surfaces
The method you choose will depend heavily on the type of surface the glue is on.
Removing Gorilla Glue from Wood:
- Gentle approach: Try isopropyl alcohol first, followed by mechanical removal with a wood scraper. Be very cautious to avoid scratching the wood's finish. Sanding may be necessary after removal.
- Stubborn glue: For extremely stubborn glue, you might need to use a heat gun (carefully!), followed by scraping.
Removing Gorilla Glue from Fabric:
- Freezing: Freezing the glue can make it brittle, making it easier to chip away. Place the fabric in a freezer bag and freeze for several hours.
- Mechanical Removal: Once frozen, try to carefully flake away the glue with a dull knife or scraper.
- Solvent Caution: Solvents can damage fabric dyes, so test carefully on a hidden area.
Removing Gorilla Glue from Skin:
- Mineral Oil: Apply mineral oil to the affected skin area and let it sit for a while. The oil should help loosen the glue.
- Soap and Water: After the oil, try to gently scrub the area with soap and water.
- Professional Help: If the glue is causing significant skin irritation or you can't remove it, seek professional medical assistance.
Prevention is Key
The best way to deal with Gorilla Glue is to prevent it from getting where it shouldn't in the first place. Here are some tips:
- Use masking tape: Protect surfaces you don't want glued using masking tape.
- Work in a well-ventilated area: This helps reduce fumes and potential breathing problems.
- Follow instructions: Always carefully follow the manufacturer's instructions for using Gorilla Glue.
- Clamp items: When gluing items, use clamps to hold them in place and prevent accidental bonding.
Conclusion
Removing Gorilla Glue can be time-consuming and require patience, but with the right techniques and careful attention, it’s manageable. Remember to always prioritize safety by wearing protective gear and testing your chosen method on an inconspicuous area first. If you're unsure about how to proceed, it’s always best to seek professional help. The tips and methods in this guide should provide you with a solid starting point to tackle your Gorilla Glue mishap.
