To remove silicone sealant, clear the area surrounding the sealant, wash the entire tile area, and cut the sealant away from the tile. Residue can also be removed with chemical agents that won't scratch the tile.
- Clear the work area
Remove all personal items from the surrounding area to keep them from getting wet or damaged. Give yourself plenty of room to work.
- Wash the tile area
It is best to wash the tile with a tile cleaner that eats through soap scum without leaving a film on the surface. If you don't have one, you can use a hot water and mild dish detergent solution.
- Cut the bead away from the tile
Carefully cut along one side of the silicone bead with a utility knife. Get as close as you can to the tile without scratching it. When you finish that side, switch to the other side.
- Peel the bead off
If you cut it correctly, the bead should all come off at once, bringing with it the silicone that filled the inside of the joint. Help it along with a putty knife, if necessary.
- Wipe off the residue
Use a scouring pad dampened with alcohol or acetone to rub off any remaining residue. Scrub when you have to, but avoid soaking the pad or tile area.
