It will leak even more then. I haven't had any luck, I sprayed WD40 on it and just worried it out. Bill

Once the silicone has cured, it's hard as heck next to impossible to dissolve it. If it is intact and has some mass to it, you can get a razor blade under a portion of it and pull away slowly and gently. Just about any solution to dissolve it will probably be harmful to you and the surfaces around it. Some applications and brands can be loosened up with a mix of mineral spirits and rubbing alcohol. I've heard that a scrubbing pad or scraper and vinegar works too, but I haven't tried these removal techniques. Sometimes you can just rub it off, but then there is the nasty residue.

Many years ago I built showcases for a jewelry store in gloss black Formica, and just set all the glass in rabbets for a very flat look. I could get the wet silicone off right away, but the dried stuff was there to stay. I called GE and their service rep could not (or would not) recommend what to use. I wound up using a piece of Formica, cotton rags and alcohol to clean up what was left. It took a long time.

For what it isn't worth, there are products on the shelves to remove old silicone. If you find one that works, let us know!

I couldn't find anything that worked other than a liberal application of elbow grease.

Silicone removal

On my fiber glass travel trailer, I use a knife or razor blade to remove the bulk of it. Then I use mineral spirits on a small piece of paper towel and scrub the rest away. Been doing that for years.
