Great to hear your project is progressing well, Eileen.
If your speaking of errant smudges of silicone, you can use denatured alcohol to help loosen & remove silicone. Sometimes you can rub most of it off with a finger first, then clean remains with aclohol, or even a lacquer thinner, but use caution & test a scrap of laminate first before using thinner. I've used it successfully on many laminate tops without a problem, but you always want to be sure first.
If you have a lot of dried excess silicone around the sink edge, I'd suggest a plastic putty knife, first scoring the silicone beside the sink, then laying the putty knife flat beside the sink and scraping the excess up from the laminate. Once the excess has been removed, clean the remainder with denatured alcohol.
Ideally, the caulking line at the sink would be "tooled" to a finish prior to drying, and the later removal process may leave a bit of a ragged edge, so once you've clean it back it may be necessary to apply another bead of silicone to make a clean, smooth joint. If you need to do this, apply a very small bead of silicone at the joint, and immediately tool it smooth using a fingertip, frequently wiping your finger clean on a rag dampened with denatured alcohol as you work. Apply the silicone to one edge of the sink at a time, tooling it to a finish before applying to the next side. Some silicones will begin to gel or get a "skin" rather quickly & becomes harder to tool when allowed to set for too long before tooling. Good luck!
