Since I have no idea what you're talking about, I'm going to take a stab in the dark and say that Polish is in the health and beauty aisle, next to the nail polish remover and the nail files and trimmers. I'm not a woman but I know that much. I also know that polish comes in all sorts of different colors and brand names.
There is also shoe polish, which I think would be found in the shoe department, next to the replacement shoelaces.
There is polish for metals and chrome, which is in the automotive department.
It also helps establish your intelligence if you are able to tell the difference between excrement and Shinola, which Steve Martin was able to do at the beginning of the classic 1979 film "The Jerk."
So, that is my best possible response to the question, "Where's Polish?" Good night, and good luck.
