How to remove epoxy glue from metal: What you need

Here is a basic overview of the tools and supplies you will need to remove epoxy resin from metal objects.

• acetone (preferred) or rubbing alcohol
• paper towels
• scraper or razor blade
• steam unit or steamer basket for small parts
• mineral spirits and a cloth

Also, ensure safety. Work in a well-ventilated area and wear gloves and safety glasses.

Two effective methods to remove epoxy from metal

We will outline two methods for removing epoxy glue from metal. Both are effective; however, since materials and epoxies vary, one may work better than the other for your job.

The first method uses a solvent to loosen the epoxy:

1. If the metal part is small enough, soak it in a container with acetone (nail polish remover). Rubbing alcohol may also work if you prefer or if acetone is not available. 
2. If the object is too large to put in a container, soak paper towels in the solvent and then wrap them around the epoxy stains.
3. Allow the epoxy to soak in the solvent for 30 minutes, re-moistening if necessary.
4. Unwrap the item or remove it from the container and scrape off the loosened epoxy with a scraper or razor blade. Be careful not to scratch the surface of the metal.
5. After scraping, remove any remaining residue with paint thinner and a cloth.
6. Wash the area with soap and water.

Another effective method is to use steam to soften the epoxy. For a small item, try a stovetop or electric steaming pot. Or you may use a steam unit meant for wallpaper removal which can be found at most hardware stores or rental shops.

1. Apply steam to the epoxy for up to 30 minutes to soften it up.
2. Use your scraper or razor to remove the epoxy. 
3. Reapply steam as often as needed while you work.
4. Use caution when working with steam and hot metal parts!
5. When all is removed but a residue, allow the item to cool, then use a rough cloth and paint thinner (mineral spirits) to wipe the area clean.
6. Wash the area with soap and water.

What to keep in mind when removing epoxy from metal 

If you find yourself with epoxy on metal, it must mean you’ve been doing some repairs! The thing to keep in mind is that not all epoxies are created equal. There are various types of epoxies with widely varying characteristics. Make sure to choose the right one for your job. 

If you are repairing metal tools, machinery, appliances, or the like, you’ll want to make sure to use an epoxy that is specially designed for metals. Loctite Epoxy Weld Bonding Compound is the perfect choice. 

This two-part system is mixed in equal volumes and will bond iron, steel, aluminium, brass, and most other metals. It cures to a metallic grey finish that can be sanded, drilled, and painted, so you can essentially rebuild broken parts. Think of it as a convenient alternative to welding.
