USA Pan Quarter Sheet Baking Pan 5 "A Strong Sturdy Tray" c00kiemonster36 07 September 2018 Thanks Lakeland for stocking these brilliant pans from USA Pans. This is commercial grade bakeware for home use, as long as you don't put this in the dishwasher, these pans will outlive you. I use these daily in my micro bakery, and they are fantastic to use. Everything bakes evenly, and the tray doesn't warp at all. Best of all when you've finished using them, all you need to do in most cases is simply wipe them clean with some kitchen towel. If you do put these in the dishwasher, the non stick coating will get eaten away by the salt (I've done it!!) Hand wash only is the key here. A note from the team Thanks for placing your review. I'm delighted to hear how much you like this range of pans. We agree with you - these pans are NOT dishwasher safe.
