Apply heat for easier removal To get rid of stubborn sealant, try applying heat using a heat gun or a hair dryer. Direct the heat towards the sealant for 30 seconds to 2 minutes at a time. Next, check to see if the sealant is soft enough for removal. If it's soft enough, gently remove it.
Among the easiest and most affordable are vinegar, alcohol, and WD-40. If you need something stronger, you can use industrial-grade isopropyl alcohol, and we recommend contacting a professional. Once you have the silicone solvent option of your choice, apply the softening agent thoroughly to all areas of the silicone.
Soften the residue.
If the residue is from a silicone sealant, try UniBond Silicone Sealant Remover. Alternatively, apply a cloth soaked in white spirit or methylated spirit. If in doubt, test the product on a small area of the residue first, and check for any discolouration.
WD-40® is very good at removing silicone sealant, but make sure you completely remove it from the surface before applying any new silicone sealant, as they can react.
Once you're removed most of the silicone, use a cloth and some methylated spirits to wipe the remnants off. The methylated spirits act as a solvent in this scenario helping break down the last of the silicone and making it easier to manage and less sticky.
While sealant removers and methylated spirits are often sufficient to remove the silicone sealant, some parts of the silicone may still refuse to budge. To get rid of stubborn sealant, try applying heat using a heat gun or a hair dryer. Direct the heat towards the sealant for 30 seconds to 2 minutes at a time.
Yes! In fact, Goo Gone is an excellent caulk remover that's every bit as good as something like Motsenbocker's Lift Off. If you opt for Goo Gone, double-check the label to make sure you've grabbed Goo Gone Caulk Remover and not another product. Regular Goo Gone Adhesive Remover can also work in a pinch if need be.
The acidity of vinegar has the capability to break down the silicone polymers, making the sealant less effective over time. This could result in leaks, moisture intrusion, and the need for premature reapplication.
Both UltraClean™ and VeriClean™ are based on the chemical “siloxane” which is a chemical “cousin” to silicones. Since “like dissolves like” in the chemical world, siloxanes dissolve silicone glues, inks and coatings quickly and easily.
Certain solvents can dissolve or weaken silicone sealant. Solvents such as acetone, alcohol, and mineral spirits can degrade the sealant, making it less effective at providing a tight seal.
There are several substances you can use to soften the silicone. We recommend vinegar, white spirit or a sealant remover such as Unibond or WD-40. Before you begin the application, start by clearing the area you're working in to avoid getting anything dirty or damaged.
Silicone Sealant Remover: This is a chemical solution designed to dissolve and soften the silicone mastic, making it easier to remove. Isopropyl Alcohol: This is a solvent that can help to break down the silicone mastic and make it easier to remove.
As an alternative to silicone remover, you might try an oil-based spray lubricant. These have also been shown to break the bond the silicone has with surrounding materials and ease removal.
Try white vinegar if you don't have mineral spirits or alcohol. It's not the most popular option, but white vinegar might help soften old caulk. It also shouldn't do any harm to the surface you're working on. Soak a rag and leave it on the caulk, or fill a spray bottle and spritz the area to soften the caulk up.

The easiest way to dissolve silicone sealant is using a remover. You simply apply the remover to the sealant you want to dissolve, leave it for 2-3 hours and then peel it off using a remover tool or knife.
Apply mineral spirits or denatured alcohol. Use a scrub pad if possible, unless the surface is easily scratched, then use a sponge. Scrub vigorously. Before applying any solvent, test it on an inconspicuous part of the substrate.
The sodium hydroxide or the potassium hydroxide can be used for fully cracking the silicon rubber with a net structure by cracking Si-O-Si bonds in the silicon rubber and dispersing the silicon rubber in the dissolving agent.
Brief contact with rubbing alcohol typically causes no significant damage to silicone. It's often used to clean silicone items because it evaporates quickly and leaves no residue.
Use a hair dryer or commercial caulk remover to soften the silicone so it's easier to scrape off. Slice along the edges of the caulk with a utility knife. Pull the caulk out with needlenose pliers or scrape it out with a putty knife.
One item you may have on hand that helps soften silicone is mineral spirits, which is suitable to get silicone off of hard surfaces like tile, marble or concrete. For removing it from plastic or painted surfaces, however, you should use isopropyl alcohol, which won't harm the surface.
