Removing silicone from a metal surface can be tricky, especially if you want to avoid scratching the metal. You’ll want to do it with extra care during the removal process to keep the surface intact. With extra caution and the right tools and materials, you can remove silicone from metal easily without scratching it.
Here is how to remove silicone from metal without scratching it:
- Apply heat to the silicone using a blow dryer.
- Manually remove the silicone using a razor blade.
- Remove the silicone with a paint scraper.
- Use an abrasive cleaner solution.
- Use a scrubber or brush to remove the silicone.
- Use vinegar to remove the silicone.
- Pour isopropyl alcohol over the silicone.
- Try store-sought silicone remover.
- Use silicone digestants to remove tough silicone.
You can remove silicone from metal with certain products and techniques while leaving the surface unscathed without any professional help. Use this list to gather the tools you need for the removal of silicone-based caulk or sealants.
1. Apply Heat to the Silicone Using a Blow Dryer
You can use a hairdryer on a low setting to apply heat to the silicone, which will loosen up the material. This step is recommended before attempting any manual removal.
Once the silicone has been warmed up, the removal will be much easier. Avoid using a high setting or overheating the silicone so it doesn’t burn. If you don’t have a hairdryer, a heat gun works just as well.
However, if you have neither of these items, try putting it near the stove while you are cooking so that it warms up that way.
2. Manually Remove the Silicone Using a Razor Blade
A razor blade can be used to remove the silicone from the metal manually. Use caution and tilt the blade at a low angle to avoid scratching the surface. Razor blades should always be handled with care to prevent injury.
There are specific blades you can buy that are designed for silicone and caulk removal.
I recommend using MyBA 3-in-1 Caulking Tool from Amazon, as it is a perfect tool for removing silicone. This silicone removal blade features a plastic scraper for surfaces too delicate to use a razor blade on.
The MyBA caulking tool is also waterproof, making it durable enough for all your silicone removal needs.
3. Remove the Silicone With a Paint Scraper
You can also use a paint scraper to remove silicone from metal manually. Just like with a razor blade, you’ll need to tilt the paint scraper at a low angle to prevent damaging the metal surface. As mentioned earlier, applying heat with a hairdryer can make manual removal much more manageable.
The Nisaku NJP335 Paint Scraper Knife is a great affordable tool you can use to scrape silicone from a metal surface effectively. Nisaku makes a high-quality tool that is rust and scratch-resistant.
4. Use an Abrasive Cleaner Solution
Mixing a solution of an abrasive cleaner with water can help dissolve any leftover silicone, which makes it easier to scrub away the silicone gently. Bar Keepers Friend Powdered Cleanser from Amazon is an effective abrasive cleaner that can be used in the solution. This powder cleanser is affordable and has multiple uses.
Mix this abrasive cleansing powder with water to form a solution, then apply to the silicone. Let the solution sit for 15 minutes before wiping it away. Rinse the surface with water to remove any remaining residue after the cleaner solution has been removed.
5. Use a Scrubber or Brush to Remove the Silicone
You can use a nylon scrubber or a bristle brush to scrub away silicone residue gently.
When scrubbing, use gentle circular motions to avoid damage to the metal surface. The scrubbing technique works best if used in combination with the abrasive cleaner solution or a store-bought silicone removal product.
If you don’t have a scrub brush lying around, try the Amazer Nylon Scrub Brush 2-Pack Set. The Amazer scrub brush has a 2-for-1 deal, making it the best deal on the market. The brushes come with handles for effortless scrubbing.
You could also use a green scrubbing pad that you can buy at the store to remove the silicone from your metal surface. However, this needs to be used in conjunction with a cleaner or heat.
6. Use Vinegar to Remove the Silicone
White vinegar’s high acidity makes it an effective method for silicone removal. If you want a chemical-free solution, vinegar is the way to go. Using vinegar will help you loosen the silicone from the metal for easy removal.
While vinegar will not entirely dissolve silicone, it can help soften the silicone for effortless extraction.
This is an excellent method to use if you don’t want to run to the store and you already have vinegar at home. Both vinegar and silicone contain acetic acid, which is why vinegar is such an effective solvent.
7. Pour Isopropyl Alcohol Over the Silicone
Isopropyl alcohol works in the same way that vinegar does. Pouring isopropyl alcohol over silicone helps to soften the silicone. This method is effective in combination with manual removal, such as a scrub brush, scouring pad, or a paint scraper.
After letting the isopropyl alcohol soak into the silicone, gently scrubbing or scraping the silicone away should be simple. Isopropyl alcohol is a common household item that can be bought at any grocery store or pharmacy.
8. Try Store-Bought Silicone Remover
Stores sell a variety of products that are geared towards silicone caulk removal.
These chemical removal products are effective at loosening silicone for easier removal. However, they are not effective for dissolving silicone. Using these products with a manual removal method will help get the job done faster.
Weiman Goo Gone Caulk Remover
This silicone removal formula, available on Amazon, is designed to facilitate the process of removing silicone-based sealants or caulk. Spray the Goo Gone directly onto the silicone and allow it to soften for 15 minutes. The easy-to-use formula is water-based and only uses biodegradable ingredients.
WD-40 Multi-Use Product
Although WD40 is not explicitly advertised as a silicone removal product, it is just as effective as other products on the market. WD40 is a standard household product, so this is an excellent solution if you have some on hand already. If you don’t have any, WD40 is always great to have around.
Grab a 3-pack on Amazon today, or buy some the next time you’re at the store.
CRL Silicone Remover and Surface Preparation
CRL makes a more heavy-duty silicone removal formula. Similar to other products, CRL Silicone Remover softens cured silicone, making it easier to remove manually. However, the CRL formula, being the most expensive of them all, will soften the silicone the most.
9. Use Silicone Digestants to Remove Tough Silicone
Silicone digestants are an excellent way to get rid of silicone that’s tough to remove. These products cannot be purchased on Amazon, but most hardware stores carry these products. Be sure to avoid using these products near wood materials, as they can permanently damage any wood.
An effective silicone digestant to look for at your local hardware store is called Dicone NC9, which can help dissolve silicone using a non-aromatic solution.

Be Patient When Removing Silicone
Go slow and be patient with the process of silicone, especially if you are working with a scratchable surface like metal. You want to take extra care to avoid damage.
If you rush through the process, you have a greater risk of injuring yourself or scratching the surface you’re working with. Take your time with this project, as it will allow you to complete the job without damaging surrounding areas.
Use Tools and Chemicals With Caution
Silicone removal can involve some tools and chemicals that can be potentially dangerous. Always use caution when handling these objects. Safety should always come first when working on a project like this.
Avoid injury and damage to metal surfaces by using caution when removing the silicone.
Don’t Use Abrasive Objects
When removing silicone from a metal surface, you don’t want to damage the metal. To avoid damaging the metal, don’t use wire wool or a serrated knife when manually scraping the silicone.
Serrated knives and wire wool can cause permanent damage to metal surfaces. Rather than using these abrasive objects, use something smooth like a paint scraper or razor blade.
Final Thoughts
You can remove silicone from metal without scratching it using equipment like a blow dryer, nylon scrubber, bristle brush, paint scraper, razor blade, vinegar, or chemicals.
The key to removing silicone from metal without scratching the surface is using extra caution not to use tools that could damage the metal. By removing the silicone carefully, you can efficiently complete the job while leaving the metal unharmed.
