Removing silicone caulk from a sink presents it’s own special challenges than removing caulk from other surfaces, such as tile.
For one, many modern sinks are made out of stainless steel and other materials that shouldn’t be exposed to some of the harsh chemicals used in silicone caulk removal.
The other problem with removing silicone caulk from a sink is the counter surfaces that ajoin the sink. Many of these countertops, formica in particular, can also be damaged by chemicals used in caulk removal.
So, when it comes time figure out how to remove silicone caulk from a sink, we’re back to our favorite friend, the razor blade.
1) Razor Blade
Basically you want to approach the silicone caulk residue at a very shallow angle with the blade. This will avoid damage to both the sink and surrounding countertop.
2) Your Fingers
As long as you’ve been careful with your razor blade, you should still have your fingers intact. Rub your fingers back and forth across any silicone caulk residue in the sink. After a while, the caulk should begin to ball up and peel away from the counter.
3) A Butterknife
These work in a similar manner as the razor blade, with the exception that you don’t have to worry as much about scratches because of the duller nature of the razor blade.
No matter which one of these techniques you try for removing silicone caulk from a sink, the key is patience and just keep at it. Eventually even the toughest silicone caulk residue will disappear.
