My Kitchen Cook & Bake Crisper Oven Tray 1 "very unhappy" Liz 09 September 2014 This is the second oven tray I bought. I love it as it cooks chips better than any other but I bought a second one as the first one I bought lost it's coating even though I do not use anything harsh in it, I thought oh well try another but why ho it's gone again very expensive when my Swedish home ware store, tins have lasted years. I am very disappointed A note from the team Thanks for your feedback. We do recommend cleaning off any cooking fats as soon as possible after use using a sponge and hot soapy water to prevent a build up. We'll be in touch to help.
