I bought this griddle thinking that because Calphalon products are quality ones, this would be too. I was sadly disappointed. I followed the instructions on the package to clean, heat etc. it has hot spots and does NOT heat evenly - there is a rust ring that appeared after the first wash, as per their instructions, I am returning it. I will try another brand now.

I noticed some reviews said this pan rusts. That is typical of cast iron. You can’t leave it soaking in water. And when you do wash it it should be dried thoroughly. One way to do that is to put it on the burner and heat it up til dry. It’s always good to wipe with s paper towel and vegetable oil.

[This review was collected as part of a promotion.] Received this for Christmas (Dec 2019) and have used it a half dozen times so far. Does a great job getting a good sear / crust on meat and nice crispy edges on French toast. I've had zero problems with either food sticking or rust appearing. Cast iron always has to be fully pre-heated before putting food on it, or it will stick. Meat releases, as expected, when the maillard reaction has sufficiently occurred. Cast iron also must be always thoroughly dried (in a hot oven or over burners) after washing or it will rust. Lightly coating it with some neutral oil after dried is good too. Can't hurt to do some extra seasoning either. (Also, any rust can be scrubbed off with steel wool and salt and the cast iron re-seasoned, if rust does occur - though, if handled correctly, it shouldn't rust at all.)

WOW, the ignorance as to the proper use and care of cast iron cookware displayed in these reviews is amazing. It is cast IRON folks, unprotected it rusts, that is what cast iron does. Go look at the brake drums on your car, they are CI and they rust too. Washing your CI with any kind of soap will remove the seasoning. Maintaining the seasoning on CI is somewhat of an art. Go look on Youtube and there are tons of videos how to apply and maintain the non-stick attributes of a properly cared for seasoning. Also, CI is not a particularly good conductor of heat, not like copper or aluminum. You need to heat any CI up with moderate heat and allow the entire pan to come to a stable temperature otherwise you are going to have hot and not so hot zones.

I bought this Calphon griddle and I've used it a few times and it rusted a lot on both sides

I bought this with only one use it started rusting.

My wife and I received this griddle / grill for our wedding last year, it lasted 2 months before the coating wore off and it started rusting. Disappointing coming from Calphalon.

the metal started tarnishing as I was cooking. no good
