Removing Dishwasher Detergent Film From Wilton Cake Pans

I have always put my pans in the dishwasher.... the only time I had a problem was here....our water is very hard.... all I do is take dawn liquid to it, a brush, and no problems... now I think I heard someone say lemon juice does it too...
anyway, even if you cant get it off I dont see why it would effect the next time you use it.... most people use their dishwashers....
I think you can relax.
I've gotten a lot of my pans from thrift shops, and a few of them I bought with the dishwasher damage. I don't even bother with trying to fix them; some of them have actual damage to the finish, and others are probably just hard water deposits. At any rate, I've never had a problem with baking cakes in them, so if you don't want to bother with trying to get them fixed up, it shouldn't hurt anything.

A lot of dawn & elbow grease works just fine...
Also see if vinegar will help remove the film. Vinegar works well for a lot of things.
Like if you use cloth diapers, put vinegar in the rinse cycle to balance the ph in the diaper for your little, works great at also getting the white and not use so much harsh bleach. I have also used vinegar if my little one accidentally wet himself, gets the clothes nice and clean and no urine smell at all.

I'm with you Lisa. I don't put them in the dishwasher. It looks like water spots of something on it. I did notice that once I changed my dishwashing tabs, it looks a lot better on the old pans. I just don't want my new pans in there.
I don't get spots...just a white film. After running them through the DW, they never really look new again. They do still bake just as good. I hope to have the room to hang my pans for display some day--like Jeanne G does. I think I'd need at least two rooms--LOL! Jeanne uses her whole house 
Thanks all for your great responses. I can't believe so many of you answered my question and I appreciate all your info. I will make sure to stay tuned to this forum and, hopefully, be able to offer some help to somebody else in the future. ZONIEGIRL
Unfortunately once the wilton aluminum pans are subjected to the dishwasher...there isn't anything that will take the oxidization away!! However...even though the pan doesn't look that great ,it is still very usable and won't effect your cakes.There is something in the dishwasher detergent that makes a chemical reaction with the aluminum and discolors it!!!
