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.
You should not have to replace these any sooner than 10 years if cleaned and stored carefully and honestly, most pieces should be a one-time purchase. Even those aluminium foil disposable baking pans and chafing dishes can be reusedif you buy quality. I buy the best quality i can with the fewest frills.
How long will a nonstick baking sheet last? Most nonstick sheet pans will stay in good shape for one to two years.
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.
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.
Peeling, Flaking, and Chipping
A non stick coating that's peeling, chipped, flaking, or otherwise damaged is a sure sign that your pan should be replaced.
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.
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.
The answer to how often you should replace your baking trays depends on how often you use them, the material of the baking tray sheet and how it has been washed. We recommend changing your baking trays or at least assessing them every year.
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.
Burnt Food Residue
If food or oils are burned onto the pan's surface, they can create blackened areas.
A cookie sheet is another baking tool that is commonly confused with a Baking Sheet. True to its name, a cookie sheet is ideal for baking cookies. Unlike a Baking Sheet, the cookie sheet has only one raised side.
Because of their versatility, cookie sheets go through a lot of wear and tear. 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.
While cookies might become a little stale when stored for a longer period, they're remarkably shelf-stable, and can keep for two to three weeks at room temperature or up to two months in the fridge, according to the U.S. Department of Agriculture (USDA).
In a bowl, mix 1/4 cup of baking soda with a few tablespoons of water to create a paste. Spread the paste over the baking sheet and let sit for at least 30 minutes. Scrub the baking sheet using a non-abrasive sponge. Rinse the baking sheet thoroughly with warm water and wipe dry.
Browning or Rusting
However, if the appearance of a browned pan bothers you, replace it with a newer, shinier model.
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.
Wash cooled sheets by hand with water and a gentle grease-busting dish soap. Dry your cookie sheets immediately with a cloth or paper towel to prevent rusting. Take care to dry the underside of the rim where water gets trapped.
If it's looking dinged and dented, mottled with stains and a far cry from its former shiny self, you may be tempted to throw it out and get a new one. Don't! Or rather — do get a new baking sheet for your cookies, but don't throw that battered and blackened one out.
Do You Need a New Sheet Pan? If it's constantly warping, yes, that's a bad thing and you might just need to buy a new, sturdier pan. But if your pan's getting dull or dark, it's actually a good thing because you'll be able to get even more delicious browning.
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.

Signs That Reveal It's Time to Get Rid of Old Cookware
Here are some important old cookware details to look for: Nonstick cookware is scratched or pitted. Pan bottom is warped and doesn't sit flush on the cooktop. This will cause uneven cooking.
While there is no exact timeframe of when you should replace your cookware, most nonstick cookware items will remain good for about five years. This being so, you can do things to ensure that your pots and pans remain in good shape for as long as possible.
