Bests & Worsts Reviews from Amazon

i enjoyed the large surface area of the pans, able to fit a lot of potatoes (fried potatoes) at one time. i recently am having health issues that lead me to examine things I've overlooked. this is a review of the Baking Sheets (BS) not a health seminar so i will sum it my simply saying i am now eliminating anything potentially contributing to having heavy metals in my system. i am not saying these baking sheets are the cause of my issues but i will no longer be using these baking sheets, and i will show you why. Most of the time i use these BS twice a day for about two months. when i first received these BS i washed them prior to using it, and noticed it made the soap look gray as if i washed off some of the aluminum. In a rush to use the BS i wiped off excess moisture off with paper towel and noticed some sort of sediment or metallic debris on the paper towel. This has been going on after each wash. i overlooked it cause i enjoy that i was able to fit so much on the tray. it was recently i discovered that my body is now showing signs to too much heavy metals that i now am taking actions to limit anymore unwanted toxins. it took about 3 separate paper towels to remove all the debris. (sometimes it took more) I've been cooking with these BS since April 2018 it is now November 8th 2018. I've now discarded them.
