Well, it depends on how often you use them. If you're someone that lives in the kitchen and cooks with the pans more than three times a week, you are looking at a life expectancy of four to five years.
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.
At what point should you replace a baking sheet? The lifetime of your pans is dependent on how often you use them. "[But] for someone who cooks pretty often, they're using that pan more than three times a week, you should be turning over your pans every four to five years."

Comments Section Aluminum is totally safe. Yes, it is safe. It makes no difference if aluminum is scratched. There is no danger. When nonstick is scratched, some more of the nonstick can flake off and get into the food and be dangerous. When aluminum is scratched is oxidizes immediately, rendering it safe.
Vintage aluminum cookware that is pitted, scratched, or worn out can be unsafe to use for cooking. Severely worn out vintage aluminum utensils can leave behind toxic metals in food after cooking, and cooking acidic foods in vintage aluminum cookware should be avoided.
For light scratches, a little Flitz Polish on a microfiber with some gentle rubbing will generally do the trick. Just make sure to use as little polish as possible and remove any remaining polish with a soft cloth.
You may notice when your pots and pans start to lose their shape — these are often signs of age with stainless steel or aluminum cookware. Food may not cook properly if your pans begin to warp, as heat will be unevenly distributed or certain areas on the pot are hotter than others.
Answer: What it means is that your pans, which are aluminum, have oxidized and they oxidize.
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.
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.

Lightweight aluminum is an excellent heat conductor, but it's also highly reactive with acidic foods such as tomatoes, vinegar, and citrus juice. Such items can cause aluminum to leach into food, imparting a metallic taste and leaving the cookware with a pitted surface.
Aluminum oxide appears as a powdery white or dull gray coating. As oxidation occurs, it hardens and creates a protective layer over the newly exposed areas of corroded aluminum.
White vinegar and coarse salt are everyday products that can be used to clean your oxidized aluminum. To properly prepare this mixture, heat white vinegar in a saucepan and once hot, pour in coarse salt. As with the previous methods, mix together until you have a paste that is liquid enough to soak into the aluminum.
Stainless steel comes out on top here, however, as hard-anodized aluminum will likely need replacement within two to five years after the purchase date. Well-made stainless steel cookware from a reputable brand will last a lifetime.
In general, you want to replace nonstick pans after five years. But you need to be particularly careful with nonstick cookware produced before 2015, as it may contain PFOA. If your cookware dates back to 2015 and earlier, it's likely time to replace it even if it doesn't contain PFOAs.
For a home cook, a decent set of cookware should last between five and ten years, depending on the frequency of cooking. "The best type of material to use in general is stainless steel, with the exception of using non-stick for omelets," explains Scott Clarke, a chef and owner of Blue Monkey Catering.
During cooking, using worn or pitted aluminum pots and pans can transfer aluminum to food more easily. Leafy vegetables and acidic foods, such as tomatoes and citrus products, absorb the most aluminum from cookware.
Many people who don't know how to make aluminum shine without polishing it will use WD-40, a Scotch-Brite pad, and some elbow grease to achieve a brushed look. The result is a bit more hazy and gray than you'd find with something that's been polished to look like chrome.
Whitening toothpaste is actually a mildly abrasive cleaner. This method can be used on light to semi-deep scratches. Before you apply your toothpaste, you will need to ensure your stainless steel surface is clean and ready to go. Apply the toothpaste to the scratched area and rub it in with your finger or a toothbrush.
