Once you have softened the silicone, you should be able to remove it by scraping it away with a sharp blade, pocket knife, or small utility knife. Be sure not to use too much force while scraping the silicone as it may damage the surrounding area. The silicone should come off rather easily. If not, you may need to heat the surface before attempting removal again.
When scraping the silicone, cut as close to the underlying layer as possible. You can also peel the silicone back as you make progress. Simply start at one end and take your time as you
make your way through the entire strip of silicone caulking. Do not worry if there is residue left after scraping the silicone, as it will be easy to remove later.
