There are several ways to remove duct sealant from your home or business property. One method involves using a putty knife and scraping the sealant away from the surface. This method works well if there is not too much of it covering the area where it needs to be removed from.
Another method involves using a chemical cleaner, such as lacquer thinner or acetone, which will dissolve the sealant so that you can wipe it away with a rag or paper towel. You can also use a heat gun on low setting to soften up the sealant so that it will wipe away easily with no residue left behind after removing it from its surface location.
