How to remove silicone sealant
Old silicone sealant can really look unsightly when it goes moldy and discolours, normally found around the bottom of showers and around the edge of your bath. Bathrooms and showers are damp warm environments where microbes live and multiply, so its no wonder your silicone is looking moldy, especially if the old silicone doesnt contain any type of antibacterial protector like the brand MicrobanŽ for example, MicrobanŽ antimicrobial protection is built-in to most new silicone sealants during manufacturing to provide continuous antimicrobial product protection.
- Using either a Stanley blade or a silicone removing tool (scraper), scrape away the majority of the silicone. If using a Stanley blade cut along the top and bottom, most of the silicone should come away in one big piece.
- Use a silicone removing compound ( fairly inexpensive). follow the instructions to the manufacturer, which normally details leaving the compound on the silicone for 5- 10 mins.
- Wipe the silicone removing compound away, hopefully the rest of the remaining silicone will be nice and loose and easy to remove.
- Once all the silicone is removed the remaining surface will need a really good clean with some water & disinfectant.
- Rinse thoroughly.
- Completly dry the surface
- ***Completion ***you are ready to re-seal your bathroom/shower room. Remember to use a Silicone with Microban or similar.
Silicone is a tricky sealant to use, even the professionals will tell you how difficult it is (check out the How to apply silicone sealant article for more information)
If removing just a small amount of silicone to tidy up where you have been applying it you could try using a stanley knife blade (only use the knife blade when the silicone has cured), but do be careful not to cut yourself.
