To remove silicone, follow these steps. First, clean your tile with a mild dish detergent. Then, use a utility knife to cut the caulk seam. Hold the knife near the base of the silicone and slide it down the seam. Be careful not to cut through the wall. The goal of caulk removal is to loosen the edge of the caulk seam. Make shallow cuts using the knife tip.
The next step in removing silicone is to soften it by using a solvent. Isopropyl alcohol is ideal for painted surfaces and plastic objects. Xylene and toluene also work well for this purpose. Vinegar, however, is a natural solution that is able to soften silicone. Be sure to follow the manufacturer’s instructions and safety precautions when using any solvents.
Another method to remove silicone is with a squeegee, a knife and a hair dryer to melt the silicone. To avoid damaging the surface, it is better to use a plastic scraper tool. It is safe to use this method on glass, but be careful not to smear the glass with abrasive substances. A silicone softening agent can break down the silicone and loosen the adhesion between surface material and the silicone.
