Silicone caulk provides a watertight seal around bathroom fixtures, windows and in other areas where moisture is a concern. Unlike other types of caulk, silicone cannot be painted and may begin to look dirty or dated after a time. The same waterproof properties that makes the silicone useful also makes it difficult to remove. While solvents are available, these may damage the surface to which the caulk is adhered or may not remove the caulk completely. Physical removal ensures the caulk is completely removed with no damage to the remaining surfaces.
Slide a razor blade between the caulk and the surface to which it is adhered. Move the blade down the length of the caulk bead, separating it from the surface. Repeat on the opposite side of the bead so both sides are pulled away from the surface.
Slide the tip of the razor blade under the end of the caulk, lifting it up. Grasp the loose end of caulking and pull it slowly away from the surface. If the caulking breaks, loosen a new end with the blade and resume pulling it away from the surface.
Soak a cloth in denatured alcohol. Lay the cloth over the remaining caulk residue and leave it to soak for 10 minutes.
Scrape away the softened silicone caulk residue with a glass scraper or flat razor blade. Scrape only the caulk and do not allow the blade to dig into the surface, especially plastic or Formica surfaces that are easily scratched.
Soak an abrasive sponge in denatured alcohol and scrub away the remaining caulk residue. The silicone caulk will bead up into small balls, as it does not dissolve. Press a paper towel onto the balls and lift them away from the surface.
Wipe the now caulk-free area clean with a cloth dampened in water. Allow it to dry completely before re-caulking.
