Cleaning Pesach Products
Question
When purchasing products for Pesach from stores that sell Chametzdik items, how careful should one be about wiping off the Pesach items before putting them on your Pesach countertops, etc.? Example: I bought some bottled water from a regular supermarket. They were put into a shopping cart, then on the usually-slightly-dirty belt, then put into bags. Should one wipe them down with a dry paper towel before them entering the Pesach kitchen? Spray them with a cleaner? What about K-P unopened wine that you own that's been out all year in your dining room. Can you just wipe it with a dry paper towel and put it on the seder table? My FFB chavrusah says "of course', so I don't know if I am just being B.T. by worrying about it. Thanks! [Agudah member too embarassed to ask his posek]
