With frequent use, baking sheets can eventually show wear and tear. Perhaps the most obvious sign of a well-loved baking sheet is when it has browned and lost its natural shine, but that doesn't mean you should throw it out altogether. A well-made baking sheet should last a lifetime, even with stains or scratches.
Assuming that it is a shiny aluminum baking sheet, which many cooks prefer, it's time to replace it when it looses its shininess. As they darken over age, they absorb more heat, rather than reflect it, and it makes things like cookies get too brown on the bottom.
For those who are cooking with baking sheets once or twice a week, you can usually scrape by with replacing them every six or seven years, according to Smith — that is, if you're taking care of them properly.
You can use rusty baking sheets without worrying about getting your food contaminated. Rust is iron oxide, which isn't a health hazzard. You can also line your baking sheet with parchment paper. That would prevent any contact between your baking pan and your food and also make for very easy cleanup.
If the frying pan is''non-stick'' and the surface is flaking,stciking or very rough it should be replaced. If it is stainless steel or aluminum and is warped so it does not sit evenly on the burner it should be replaced. If it is cast iron or carbon steel it can be cleaned, reseasoned and good as new.

If you've got rusty or damaged cake pans it's really time to get some new ones. Baking with rusted or peeling bakeware is simply not worth the risk to you, your family and friends' health.
No. While they don't necessarily present a safety concern, you still shouldn't hold onto your scratched nonstick pans. If the scratches are fresh, you may end up with flakes of the coating in your food, which we can all agree is not delicious.
If your nonstick pan or bakeware is extremely scratched and/or the nonstick coating is beginning to chip off, not only will food begin to stick to the pan, but bits of the coating will mix in with your food. VERDICT: It's time to let that pan go.
If you use a sheet set every day of the year, you'll need to replace it after about two years. However, luxury cotton sheets, like percale and sateen, can offer another year or so of use. And with linen, you'll get three to five years — sometimes more.
A dirty pan vs.
Grease, burnt-on bits of food, and basically any kind of debris left on your baking sheet after cooking count as grime that should be washed off. Seasoning is the same thing as seasoning on a cast-iron pan: layers of hard, polymerized oil baked onto the pan over time.
If you bake weekly, sheets need to be replaced every two years. If baking is more sporadic, they need replacing every five. However, how you care for your bakeware can prolong its life. Some bakers' sheets will last a lifetime.

It flakes off as more and more rust forms and eventually the iron crumbles away. Rust is not a food safe material so it should not be ingested. If you see rust on the surface of a utensil such as a cast-iron skillet or knife, remove all the rust before using it.
If you notice that your baking pans are developing rust, the best decision would be to replace them with new ones. "The risk far outweighs the benefit of trying to recover the baking pan," Le says.
The biggest difference between a cookie sheet and a baking sheet is the former doesn't have a rim around the edge. Some will have a bent lip on one side, making it easy to grab with potholders. Without the rim, it makes removing hot cookies much easier since you don't have to maneuver the spatula around any edges.
How to test if baking powder is still active: pour 1/4 cup boiling water over 1/2 teaspoon baking powder. If it foams, the baking powder is still good. If not, it's dead.
“It's reusable up to three times. We recommend against saving the sheet beyond that use. If the dough has ingredients that melt onto the paper (i.e. chocolate chips/chunks) and cannot be wiped off, use a new, clean sheet to avoid remnant ingredients from burning onto paper or ruining your delicious results!”
We advise replacing your nonstick pans whenever the coating starts to degrade or is scratched—or about every three to five years.
If it's the first time food is burnt on the pan, it should be fine. Otherwise, it's not ideal to continue cooking or eating food from a burnt pan that hasn't been cleaned. Try to clean a burnt pan as soon as possible after it's burnt so that the chemicals don't transfer to your food.
