Cast-iron pans might be your most prized culinary possessions. They're sturdy, long-lasting, and are often passed down for generations. But to keep them in pristine condition, you'll need to take care of them properly. So, what happens when you have a bit of rust on the bottom? Enter the affordable household item you likely have hidden in your cabinets: aluminum foil.
To start, a warning. This method is a last-ditch effort and best employed if you are already fairly confident in your piping skills. It's not the easiest solution to this problem, but it can work in a pinch. We tried it ourselves after doubting it, and it proved itself to be another reliable foil hack around the kitchen. You'll need to layer your foil, especially if you have a very thin brand.
The simple answer is yes, you can technically microwave aluminum foil, as long as the manufacturer clearly indicates that your model can handle the foil in the device's manual. However, there are specific conditions that need to be met. Most importantly, the foil needs to be kept as flat as possible. When foil is bent or wrinkled, a phenomenon known as "arching" occurs.
