How can I remove silicone that has seeped from where it was supposed be? Also, I seem to have a drop or two on the project that I couldn't see (clear silicone on clear glass). What is the best way to remove unwanted silicone?

Thanks. I've been using a razor. If anyone knows the name of the solvent, I would appreciate it. I have a few stubborn smudges that are difficult to razor off. Ugh.

It's not really a solvent (I don't think anything totally dissolves silicone), but it does soften it and makes it easier to remove.

I find that there are two issues with removing silicone. First, it's sticky and seems to re-stick when scraped off. Second, it's nearly invisible and becomes more so when scraped a bit.
So, in addition to the razor, I dust with whiting lightly to prevent re-sticking and sort of highlight the residue. Also, the silicone can be removed using a rough cloth with the whiting or even 0000 steel wool (not appropriate for all surfaces, of course).
I'd guess that any fine, dry powder would work; I just happen to have plenty of whiting ;- }

Thanks. I'll give both a try.

I start with a razor blade, and finish with acetone.
