To remove silicone sealant, scrape the majority of the sealant away with a knife, and dissolve the rest with a flour paste. You need gloves, a knife, white flour, water and silicone remover.
- Scrape the sealant away
Put on the gloves. Apply water to the silicone sealant to moisten it. Use the knife to scrape away as much of the sealant as you can manage. Apply more water as you go to keep the sealant moist and easier to loosen.
- Make the flour paste
Place 1 cup of white flour in a bowl. Add a few tablespoons of water to the bowl. Mix until the two ingredients form a thick paste. If it is too runny, add more flour. If it is too thick, add more water. Apply the paste along the silicone sealant, and allow the paste to dry.
- Rinse the paste
Rinse the dried paste with water until all of the silicone sealant is removed. If any sealant remains, use a silicone remover, such as Re-Mov. Apply the removing agent to the edge of the line of the sealant. Allow the remover to spread, and loosen the sealant from underneath. Wipe the remover away with a cloth to finish.
