Report Abuse. No the aluminium foil will spark,pop etc. in your microwave oven and that will ruin your microwave oven. If you want to reheat something in the microwave oven put it on a microwave safe plate and cover it with saran wrap and fold back a corner for the steam to escape.
Foil. What it's best for: If you're refrigerating something smelly, foil creates a stronger barrier to keep odors in. Just be sure to seal as tightly as possible. Foil is also ideal if you'll be reheating the food in a conventional oven, since it can withstand heat. Tips for using: It's a good idea to wrap a snug layer of foil around plastic-wrapped foods you plan to freeze (like meat in its unopened packaging), because it keeps out oxygen, which causes freezer burn. Definitely don't use it in the microwave, and never wrap acidic foods, like tomatoes and berries, in foil. The acids react with the aluminum, leaving a harmless but unsightly blue residue.
