How to Get Silicone Off of a Countertop

If you lay tile or work on the plumbing in your home, you will likely work with some silicone. Due to the fact that silicone is waterproof, it is widely used in both tile and plumbing caulk. Once dry, silicone creates a solid adhesive barrier that doesn't come up easily, which can make it a problem if you spill any silicone on surfaces, like countertops, during application. With a little work, you can get silicone off of a countertop.

Waterproof silicone can be a mess to clean up.

Step 1

Remove as much of the silicone from the countertop as you can by pulling the dried silicone from the surface. Make slices under the edges of the spilled silicone with a utility knife. Work the end of the silicone up gently with the tip of the knife, touching the counter as little as possible, and then grip it tightly and pull it upward. If the silicone breaks, work the end up again and continue pulling the silicone up from the surface.

Step 2

Place the sharp edge of a razor blade down against the counter at a 20 to 30 degree angle at one edge of the dried silicone. Slide the razor blade along the counter, working the blade beneath the silicone on the counter's surface. Press just hard enough to break the silicone free of the countertop.

Step 3

Dust the silicone bits from the countertop with your hand or a dry rag. Moisten the rag with mineral spirits and scrub the area from which you removed the silicone thoroughly to take off the leftover silicone. Though Tom Silva of This Old House recommends an abrasive cleaning pad, this type of pad may scratch many varieties of countertop, such as stainless steel and laminates.
