Once you have removed the silicone caulk from around your tub or sink you are going to be left with a residue that you will want to eliminate. This residue will often make the surface of your sink, tub, or ceramic tile appear dull, or chalky.
The best solution to clean away this residue is plain soap and water. Mix some dish detergent in warm water to create warm soapy water and apply liberally to the silicone caulk residue.
You need to rinse the warm soapy water away using clean water, and then thoroughly dry the area where the residue was.
It may take two or three cleanings before all of the residues is completely erased.
