Removing silicone caulk residue effectively is a two or three part process.
Clean silicone caulk off tile.
Clean off the residue with soap and water let dry and then recaulk.
Prepare the surface for the task by cleaning the space surrounding the silicone caulk with a cloth dampened with rubbing alcohol.
Another great cleaner when using silicone caulk is goo gone which is very mild and will do a variety of different clean ups including hands.
How to remove silicone caulk residue step 1.
The caulk remover works by destroying the bond between the caulk and the tub or tile so that instead of chipping at the caulk with a razor blade you just pull away big chunks of it with a putty knife.
When using silicone caulk take some precautions and find the materials that work best for you.
Alternatively use hot water and a mild dish detergent.
Most removers work on both silicone and acrylic latex caulks.
You can also use silica sand with water and abrasively remove it with a scrub pad.
Then hold the scraper at a shallow angle to avoid scratching the surface and remove any remaining caulk.
Brush away any.
My experience is that silicone isn t too difficult to remove.
Washing the tile before.
After this thoroughly dry the surface with a cloth.
Use a scrub pad if possible but if the surface is easily scratched.
Next scrub the surface with an abrasive pad soaked in mineral spirits to get rid of any silicone residue which will prevent the new sealant from sticking.
If it still leaves a film residue on the surface of the tile you could try to use xylene acetone or goof off with a scrub pad.
Answer silicone residue is normally removed with a razor blade scrapper.
Softening the residue by prolonged exposure to mineral spirits loosens its bond with the substrate.
Use a razor blade to scrape off as much of the residue as possible without scratching the surface you are.
Apply mineral spirits or denatured alcohol.
