Step-by-Step Removal
1
Apply caulk remover (optional)
Apply gel to old caulk and wait 2-3 hours. This softens silicone and makes removal much easier.
2
Score along edges
Run utility knife along both edges of the caulk bead to break the seal with the surface.
3
Pull and scrape
Grab an end and pull. Use plastic scraper to remove remaining bits. Metal tools can scratch surfaces.
4
Clean the surface
Wipe with rubbing alcohol to remove residue and any mold. Let dry completely before new caulk.
5
Check for mold
If there's black mold behind the caulk, spray with mold killer and let dry before recaulking.
