Use mineral water to rinse the area where the silicone caulking is located.

Moisten the caulking with a chemical solvent. There are a variety of chemical solvents for silicone caulking. Only heavy solvents will work on silicone caulk stains. Acrylic and non-acrylic caulks are easy to remove and may just be lifted from wood using only water and manual scraping. Just some of the most common and effective chemicals include Methylene Chloride, Dichloromethane, Methylene Bichloride, and Methylene Dichloride.
You need to mix the solvent with a white absorbent material to form a thick paste. Just some of the most common white absorbent material are molding plaster, white paper towels, powdered chalk, untreated white flour, white tissue, talc, fullers earth or laundry whiting.
2) Apply the chemical paste
Apply the chemical paste to the stain using a plastic or wooden spatula or applicator. Apply using a layering technique and make sure that the paste is at least 1/4 inch thick or less. This should cover the caulking and should extend past the edges as well. Make sure that this is free of any air pockets.
Allow the chemical paste to set for at least 48 hours. Cover with plastic sheeting and then seal the edges with masking tape. Follow the instructions provided by the manufacturer on the solvent label.
Dampen the area with mineral water. This softens the hardened paste and would be enough to lift it off the wood.

After the caulk has been removed, rinse the area with mineral water to remove any residue. Pat the area dry with clean paper towels.
