you've probably heard that placing tin foil at the bottom of your oven is a good idea. That was true win tin foil was made from tin. Today, it's made from aluminum and aluminum will melt in your oven.
While aluminum foil works great on the grill and on our food it will bond with the metal at the bottom of your stove.
Once that happens, it won't come off: your stove and that foil are now one. Your choices at that point are to live with it or order a new oven floor for around $100.
The Reynolds company recommends putting a sheet of heavy duty aluminum foil on the lowest rack of the oven leaving a few inches around the edges to allow that hot air to circulate around your dinner. This keeps your oven cleaner saving you time and trouble and saves your oven from permanent damage. Plus they sell a lot of tin foil that way. Well played Reynolds Wrap. Either way, don't put it on the BOTTOM of your oven.
