I'm not so sure... when I first saw the question you linked to, I thought he was talking about silicone gel, that you often see for cookware like muffin tins, cake pans and so on, which would make it off topic. Other household uses of silicone make less sense to me: I can't imagine anyone would scrape up their discolored silicone caulk, heat it and reapply it to their bathtubs, for example.
But take a look at this other question by the OP for context:
How do I know if the canister of silica gel or strips of vapor corrosion inhibitor have lose its effectiveness in absorb moisture?
It seems he's asking about a silica gel dessicant to prevent tools from rusting, which I think makes it on-topic. It just needs to be heavily edited, which I've just done.
