  1. 1

    Scrape off as much silicone as you can with a plastic scraper. The tool you use to scrape off silicone largely depends on the material that was used to make your countertop. Since most countertops can easily be scratched, a plastic tool is better.

  2. 2

    Pour rubbing alcohol or white spirit on the silicone. Let the alcohol or white spirit soak the silicone overnight.

  3. 3

    Vigorously scrape off as much silicone as you can with without damaging the surface of the countertop. Grasp any looses pieces of the silicone with needle-nose pliers. Pull out as much silicone as you can with the pliers, loosening up the silicone as you go along with a plastic scraper.

  4. 4

    Apply a commercial caulk-removing product to the silicone.

  5. 5

    Allow the caulk remover to soak and soften the silicone for the time recommended on its instructions.

  6. 6

    Cut a slice in the silicone caulk with a utility knife.

  7. 7

    Remove the silicone in accordance with the instructions listed in Step 3.

  8. 8

    Clean the area where the silicone was removed with a household cleaner that does not contain ammonia.

Tips and warnings

  • Rubbing alcohol or white spirit take longer to work than a commercial caulk remover.
