lot of vintage MANLEY toy kitchen utensils & pots plastic - AS IS

Description

I acquired these from an estate sale and when I soaked them to try to clean them I somehow created a discoloration that looks like rust on some of them.
I'm not sure how I did that because they appear to be all plastic. But maybe there are some bits of metal in there. I'm not sure.
I have not tried any rust remover. I've decided to sell as is.
Couple other things to note:
There are two pots and three lids. None of the lids fit perfectly on the pots. They are very close. Not sure if the plastic expanded or if they just never went together. One of the lids has a chip out of it.
Marked Manley Made in China.
Thanks for looking.
