When tackling the stubborn task of removing old silicone sealant, some people wonder if ordinary decorating materials can help do the trick. So let’s take a quick look and answer the common question: does white spirit remove silicone sealant?
The short answer, while nuanced, is that white spirit can generally help with the job. But it is not a great choice for bulk removal of silicone.
White Spirit Explained
White spirit, also known as mineral spirits outside of the UK, is a petroleum-based solvent. This long established product has historically been widely used in decorating for cleaning paint brushes, thinning oil-based paints, and degreasing surfaces. However nowadays there are many non-solvent based and safer alternatives on the market.
Effectiveness of White Spirit for Removing Silicone Sealant
While white spirit is a strong solvent, it doesn’t dissolve cured silicone sealant completely. Instead, the strength of white sprit lies in its ability to soften the silicone. This makes it easier to scrape away, so think of it as a helpful tool rather than a standalone solution.
