Silicone caulk is far more durable than acrylic caulk, and that's why it's often used around bathtubs and sinks. Silicone caulk holds up well in moist environments. When caulking around a sink, it's important to be careful and not spread the silicone where it's not needed. However, if you happen to accidentally spread the silicone caulk a little too far on your granite counter, there's no need to worry. If cleaned up promptly, there is a good chance that you can remove all of the excess silicone and maintain the beauty of your investment.
Wipe down your granite counter top with a microfiber cloth and warm water. You want to remove any dirt or residue that has built up so you can concentrate on removing the silicone.
Fill a spray bottle with denatured alcohol. Spray a generous amount of the alcohol over the affected area, making sure to completely soak the excess silicone. This helps dissolve the silicone.
Use a razor blade to scrape away the silicone. This may require some hard scraping, which is fine because granite is a tough stone. Continue scraping until the majority of the excess silicone is removed. Wipe away the remnants with a microfiber cloth.
Scrub the rest of the silicone away with a #0000 super fine steel wool pad. You may need to spray the granite with denatured alcohol again to achieve optimal results.
Apply granite cleaner to the counter top, and wipe it clean with a damp cloth. Polish the counter with granite polish, and buff it with a clean microfiber cloth.
Wear safety gloves to protect your hands. Try to clean up the excess silicone as soon as possible. It's very difficult to remove after it has set in.
Avoid using hard scrub brushes or harsh chemicals on your granite counter top.
