Yes, it is generally safe to wash and reuse <a href="https://en.wikipedia.org/wiki/Foil">aluminum foil</a>, as long as it's not heavily soiled or torn. Here are a few things to keep in mind:

✅ When It’s Safe to Reuse: - Lightly used: If it was used to cover food or line a baking sheet without much residue. - Not crumpled: Flatten it out gently if it’s still in good shape. - Not greasy or burnt: Grease and heavy charring are harder to clean and may affect food safety.

🚫 When Not to Reuse: - Torn or heavily wrinkled: These can trap bacteria or break apart during reuse. - Contaminated with raw meat juices: Better to discard in this case to avoid cross-contamination. - Coated with sauces or sticky substances: Cleaning can be tricky and not worth the risk.

It’s a good way to reduce waste, just be sure it’s clean and safe for the next use!
