Hi Kathleen, here's a Wicki how to! https://www.wikihow.com/Clean-a-Waffle-Iron
Here's a great post on cleaning your waffle maker.
Real steel or coated aluminum?
Old irons were really iron & have to be the-seasoned like a cast iron skillet.
Aluminum can be soaked in lots of cleaning solutions. When clean, avoid using a spray oil for cooking, as they harm the “Teflon” type coatings, according to Calphalon Cookware.
It is an old one - over 55 years old. The exterior is highly covered with burnt on food. It still works very well, but doesn't look nice. Any further suggestions?
Here's what I do.... Heat up the waffle iron, unplug then lay two layers of wet paper towels in between the plates. This steams the iron. When it has cooled down enough to handle, open the plates and wipe any stubborn spots.
Thanks. Any suggestions about cleaning the outside of the waffle cooker where food has burned on?
ok, I now know what kind you have. thanks.
The outside is probably chromed and can be cleaned with a nylon scrubber and a lot of soapy water.
The inside should be removable and I would soak them in really hot soapy water and take an old tooth brush to them or some other soft bristle brush and then soak them some more.
If they’re starting to rust, then when clean. Dry very well and then “season” them like a cast iron skillet, with “Crisco” at a low temp in the oven. (325 comes to mind, but I’d double check that).
