I have mini muffin silicone baking tray I simply love. I bake huge batches of both sweet and savory versions, freeze and reheat for breakfast or snack. However, it started to stick lately and no amount of oiling helps.
Do these have “expiry date” or a number of uses good for? Mine is at least 10 years old and did at least 3 batches every week.
Is that their normal “death” time/usage? Can I do something to extend its life, or simply get a new one? No visible damage, scratches, cracks etc. I also have a bread pan and it’s still going strong, although it might have been used less.
