Do you know how to remove epoxy from metal? If you've ever worked with epoxy on metal surfaces, you know how aggravating it can be when it drips or spills in unexpected places. In this article, we will explore different methods that will help you effectively remove epoxy from metal surfaces.

Depending on the size and shape of the metal object, you can try one of 3 different methods here to quickly remove epoxy from the metal. 

Method 1: Using a heat gun or a hairdryer

The first method we want to cover is how to remove epoxy from metal by using either your heat gun or a hairdryer. Follow the following steps to help you achieve your success: 

Apply heat

To begin, switch on the hair dryer or heat gun and adjust it to a lower heat setting. This protects the metal surface from damage caused by high temperatures. Position the heat tool approximately two to three inches away from the epoxy-coated area and heat this area in 2 to 3 minutes. To properly disperse the heat and soften the epoxy, move the heat tool back and forth.

Scrape gently with a putty knife or a chisel

As soon as the epoxy begins to soften, you may simply remove it by scraping it away gently with a plastic scraper or putty knife. Holding the tool at a little angle when scraping to prevent scratching the metal surface. This procedure effectively removes the epoxy while causing no damage to the metal.

Repeat if necessary

If the epoxy does not come off easily on the first try, it is important to reapply the heat and continue scraping. Patience is essential throughout this procedure to prevent damaging the metal by overheating it. By repeating these steps, the epoxy will gradually soften and become simpler to remove.

Clean and polish

After successfully removing the epoxy, you clean the metal with a mild soap and water mixture. Remember that you have to thoroughly rinse the area and make sure to let it dry completely. Optionally, to restore the shine and finish of the metal surface, you can apply metal polish in the final step.

*Note: You should take caution not to overheat the epoxy or the metal surface because excessive heat can cause damage.

Overall, anyone could use a heat gun or hair dryer to remove both wet and cured epoxy from metal within minutes depending on the areas you are working. Because heat guns and hair dryers have limited reach and focused heat capabilities, they work best for small epoxy areas. Besides, this is an economical solution since a hair dryer is an essential tool in your home.

Method 2: Using chemical adhesive remover

Chemical adhesive removers are a reliable option for removing epoxy from metal surfaces. Metal is known for its durability and toughness, making it capable of withstanding the use of such removers. Here are some popular adhesive removers available in the market: 

  • 3M Adhesive Remover: This remover is a blend of solvents that effectively dissolve adhesive epoxy. Its convenient wipe-on, wipe-off formula is ready to use with no need for mixing.
  • Jasco® Premium Paint & Epoxy Remover: This is a versatile product that can effectively strip multiple layers of paint and epoxy from various surfaces such as wood, metal, concrete, and masonry.
  • Goo Gone Pro-Power: This product removes epoxy from various surfaces like ceramic, metals, and plastics. It is safe, fast-working, and highly efficient.
  • Zall It's Gone Adhesive Remover: It is a plant-based formula that safely and effectively removes epoxy, adhesives, and more without any toxins. 

However, if you're looking for a more cost-effective option, you can also consider using acetone, nail polish remover, or rubbing alcohol for the same purpose. 

Soak the metal object in a bowl of chemical adhesive remover

Start by preparing a container of acetone or nail polish remover. If the object is small enough, you can soak it in the acetone for 15 to 30 minutes and cover the container with a lid to avoid evaporation. 

However, if the object is too large for a container, you can wrap it in paper towels soaked with acetone. After soaking for the recommended time, you will see layers of epoxy peeling off. If using rubbing alcohol, it may take longer for the epoxy to loosen.

Scrape off the loosened epoxy

Next, you take out the metal from the containers or unwrap the objects. Then, you use a scraper to scrape off the epoxy. Make sure you provide enough pressure to remove the epoxy completely without damaging the surface underneath.

After scraping off most of the epoxy, you may notice a slight haze remaining. To remove this haze, simply wipe it away using a rag soaked in paint thinner. Gently rub the surface until the haze is completely gone, ensuring a clean and smooth finish.

Wash the metal object

Typically, this method is a suitable approach for anyone looking to remove both wet and cured epoxy. It is quite affordable, you can buy a bottle of Pure Acetone for about $10.50 for 8.00 Fl Oz, or a specialized chemical for epoxy removal like Jasco® Premium Paint & Epoxy Remover for $50.12/gallon. 

It can take you just 15 minutes to remove the epoxy and restore the metal to its original condition. Therefore, when compared to the method of using a heat gun or hair dryer, chemical adhesive remover will remove epoxy faster and on a larger metal surface.

Method 3: Steaming the metal object

Steaming is the last method we want to introduce today on how to remove epoxy from metal properly. Using steam can effectively soften the epoxy and make it easier to remove from the metal surface. Here's how to do it:

*Note: The hot steam or water can cause burns, so you should take proper precautions, such as wearing heat-resistant gloves, keeping safe distances, etc., while working.

In general, this method is suitable for anyone who wants to remove wet epoxy from small metal objects. It is an economical solution if you have a steamer in your kitchen. Additionally, it takes more than 30 minutes to loosen and remove epoxy completely from the metal surface. Therefore, when compared with the above two methods, using a steamer to remove epoxy will take more time and is less effective.

* Some general notes for all three aforementioned methods:
