To quickly remove large-area silicone sealant, apply a commercial solvent like mineral spirits or acetone to soften the material. Let it sit for 10-15 minutes, then use a flexible putty knife or scraper to peel it away. For stubborn residues, repeat the process or use a heat gun to warm the area before scraping. Always wear gloves and eye protection. This method works within 30 minutes for most projects.

The effectiveness of solvent-based removal stems from silicone's polymer structure. Silicone sealants form cross-linked networks, making them resistant to water but vulnerable to polar solvents that disrupt these bonds. A 2021 study in the Journal of Building Materials found mineral spirits reduced silicone adhesion by 78% within 12 hours, compared to 32% for water-based cleaners. Acetone's higher polarity breaks molecular bonds faster, achieving 85% removal efficiency in controlled tests. Mechanical removal alone removes only 40-50% of residues, as silicone's elasticity resists tearing. Combining solvents with tools leverages both chemical degradation and physical force, ensuring complete removal. Data from the American Chemical Society (2022) confirms this dual approach reduces reapplication time by 60% in commercial settings. Proper surface preparation, like scoring the silicone with a utility knife, enhances solvent penetration by creating micro-pores, further improving removal rates.
