How To Disslove Silicone Sealant?

Silicone sealants are commonly used to seal gaps and joints. They are a great way to waterproof your home and prevent water damage, especially in wet areas such as bathrooms, kitchens and laundry. 

Effective sealants can typically last for years. However, due to wear and tear, the material may become discolored or damaged over time. When the silicone is no longer working correctly, you may have to clean the surface and replace the old sealant.

This article will explain how to effectively remove silicone sealant and share some helpful tips. We’ll also explain how to reapply the sealant so you can protect your surfaces from water damage.

Steps on How To Remove Old Silicone Sealant

Silicone sealants can be applied to tiles, glass, wood, and metal surfaces. You will need a silicone softening agent, a sharp edge (e.g., a blade or knife), and a cleaning solution for an at-home project. Removing existing sealant from these surfaces often requires great care to prevent scratches.

Below are the steps to effectively remove old sealant without damaging the applied surfeit is

What you will need:

  • A sharp blade or small utility knife
  • Sealant remover
  • Methylated spirits

Clearing the area of loose objects

To start, clear any loose debris from the surrounding area. You avoid dirtying or harming them when you remove the silicone sealant by keeping them out of the way.

Applying A Softening Agent

There are a few methods for removing silicone, but we have found that softening the silicone first is the best place for do-it-yourself folks to start. Naturally, start by peeling off any loose silicone with your hands.

You can use various materials to make the silicone caulking softer. Some of the simplest and least expensive are WD-40, vinegar, and alcohol. Industrial-grade isopropyl alcohol is a more robust option; however, speaking with a specialist is advised.

Once you have chosen the silicone solvent, thoroughly apply the softening agent to all parts of the silicone. Allow a few hours for the silicone to soften. After allowing the solvent to rest, evaluate the silicone for softness and looseness before scraping and removing it.

Use A Sharp Edge To Scrape

Once you have chosen a silicone solvent, thoroughly apply the softening agent to all parts of the silicone. Allow several hours for the silicone to soften. After allowing the solvent to rest, evaluate the silicone for softness and looseness before scraping and removing it.

When scraping the silicone, cut as close to the underlying layer as you can. You can also peel the silicone back as you go along. Just begin at one end of the silicone caulking strip and slowly work through it. After scraping the silicone, do not worry if any residue remains; removing it will be simple.

Remove loose pieces of silicone sealant.

You could occasionally see little pieces of silicone sealant coming off. These pieces can be manually peeled off or scraped with a sharp knife.

Alternatively, you can release the sealant by making a tiny, shallow incision at the seam. Avoid making too deep cuts, which could harm the sealant’s surface. As soon as the seam opens, you can remove the loose parts.

Apply or spray the sealant remover.

Once the loose pieces have been removed, you can apply a sealant remover to the silicone. Leave the solution on the surface according to the duration specified on the product label. The remover will loosen the sealant within a few minutes, making it easier to peel from the surface.

Remove Residue & Clean Surface

After you remove the silicone sealant, there will likely be a fair amount of underlying residue. This may include adhesive material used to secure the silicone into place, dirt, grime and worn-down paint. The residue can cause an uneven surface and make applying new silicone challenging.

Use a utility knife to carefully remove the remaining residue, making sure the surface is even. After removing the residue, clean the area with methylated spirit or soap and water.

Finally, reapply the new silicone if desired. It is vital not to keep the surface naked for too long, as this increases the risk of water damage. If there are symptoms of black mold underneath or around the old silicone, contact a restoration professional.

The Other Methods for Removing Silicone Sealant

White Spirit isn’t the only product that can remove silicone sealant. WD-40, an oil-based solvent, can also break down the sealant’s adhesive so you can also use methylated spirits or household vinegar to soften silicone sealant. White vinegar is an inexpensive alternative but is not always as effective as white spirit.

Each alternate technique can be used in the same manner as white spirit. Additionally, there are products designed specifically to remove silicone sealant and depending on the brand, these could be more costly and require more time than the white spirit approach. However, they also contain chemicals that might increase their efficacy over alternative techniques.

In Conclusion

White spirit has many practical applications in the home. It can be used as a solvent to clean filthy paintbrushes or as a paint thinner. It is also a popular element in many paints and finishes that you can get from any hardware store.

One of its most valuable uses is removing silicone sealant. Silicone sealant is a solid and long-lasting adhesive. Because of this, dissolving it entirely, unlike paint or softer adhesives, is quite tricky.

White spirit does, however, degrade the silicone material’s adhesive qualities and soften it. The silicone sealant you wish to remove will become sufficiently pliable after soaking to be easily cut away.

In a similar manner, methylated spirits, denatured alcohol, and white vinegar can help remove silicone sealant. Additionally, branded products are designed with sealant removal in mind.

Every approach has advantages and disadvantages, ranging from price to usability.

However, using white spirit to remove your outdated or ugly silicone sealant is generally an inexpensive and efficient solution.


When will I need to remove my silicone sealant?

• If your sealant has become moldy: Mold grows best in warm, humid environments, such as bathrooms. Changing your sealant when you see mold growing on it is advisable.

• When your sealant is peeling off: Waterproofing properties are lost when a sealer begins to peel. It should be changed before the seal is compromised by moisture.

• When you feel air or moisture leaking through, The sealant has most likely lost its adherence if you can feel air or moisture leaking through the seal. As soon as it stops being airtight, replace it right away to prevent further moisture or air from seeping through and causing water damage.

• When installing a new fixture: You must remove the old sealant before installing a new fixture, such as a shower screen or basin.

• When your sealant is discolored: If cleaning cannot remove the discoloration on your existing sealant, it may be time for you to replace it.

Can vinegar be used to remove silicone sealant?

Indeed, using vinegar to weaken sealants makes them easier to remove. Use caution while applying this solution, as it can etch and harm surfaces like marble and granite. We advise testing it first in a private place to limit any potential harm.
