Why do baking pans rust in the dishwasher and how do I prevent it?

Question

I'm sick of cookie sheets and pizza pans etc, rusting in the dishwasher. How can I prevent it...or can't I?

Answer 1

Dishwasher detergent is more caustic than dishwashing liquid (which is fairly neutral).

The solution is to wash you stuff by hand in the sink. ;-( You can then spray or wipe a coating of non-stick cooking spray onto the pans to keep them from rusting in the drawer.

Answer 2

All of our 'metal' baking pans rusted eventually ... so I buy the new 'silicone' baking pans now ... they 'discolor' but it's not 'rust' that can get into the 'baked goods' ... and they are so much EASIER to store, since they 'fold' and you can 'stuff them in' where a cookie sheet or pizza pan wouldn't fit. Yes, they cost a bit more, but are 'so great' that if you do a lot of baking, you should consider getting them. The only thing I don't really like is that I still have to use a 'regular' cookie sheet under the silicone one, because the tend to 'bend' through the bars on the oven rack. The COOKIES come out looking and tasting MUCH BETTER though!

Answer 3

Probably the hotter water and humidity in they cycle. Mine used to rust too now I wash then my hand. I really think the Dishwasher can harm the finish of pots and pans too.

Answer 4

Hand wash them, I think if you leave them in the dishwasher too long after the wash cycle, the drying cycle doesn't get all of the moisture off them. I use non stick ones now but still hand wash them.

Answer 5

yep, handwash these. Don't let them stay wet. Buy stainless steel. they last forever , don't rust, and you can scrub the heck out of them with abrasives.
