You don't soak pickles in brine, you soak cucumbers in brine and you do it to turn the cucumbers into pickles.
You may reuse brine only if it is to refrigerate something such as refrigerator pickles. If it is cloudy or murky, do not reuse. Also, you cannot use pre-used brine for canning.

Pickles are actually cucumbers that are fermented in vinagar or brine to preserve them. That is where they get their sour taste. It is not known specifically where the pickling process comes from, however the earliest known use of the term originates from somewhere in central Europe circa 1440 A.D.
It really depends on the intesity of the flavor you want and the kind of pickle you're making - the standard benchmark is about 2 weeks. They only take about 2 days to absorb the briny flavor, though. 2-day old pickles are known as "new pickles", while the older ones are known as "old pickles".
Typically, there are no seeds in a pickle. Pickles are cucumbers that have been pickled in vinegar or brine, which does not involve keeping the seeds.
Pickles are not typically wrapped in aluminum foil because they are already preserved in vinegar or brine, making them less likely to spoil or become contaminated. Additionally, pickles are often stored in jars or containers with tight-fitting lids to maintain their freshness and prevent exposure to air. Wrapping them in aluminum foil may not provide any additional benefit.
Polish dill pickles are typically more sour and tangy compared to kosher dill pickles, which are known for their garlicky and slightly sweet flavor. In terms of preparation, Polish dill pickles are often fermented in a brine solution with additional spices like mustard seeds and allspice, while kosher dill pickles are made using a simpler brine with garlic and dill.
