Laundry enzymes on aluminium pan

[ROSEMARY3001]

I recently boiled up some tea towels in my aluminium preserving pan, to get rid of an unwelcome scent caused by using them to keep chappatis warm. I added some laundry detergent with "stain-removing enzymes" in it. The pan has turned a bit black, which I understand from googling, is caused by oxidation, and is not a problem for subsequent use. However, I am wondering if the enzymes have done any more serious damage which might flavour future cooking or present a health hazard. I've boiled some water and tasted it - it seems ok, but I know that's not conclusive! Anyone have any idea?

Maybe try astonish oven and cookware cleaning paste and see if you can remove the black marks

Thank you, that sounds worth a try.

I use Barkeepers Friend a lot. Not sure if it would work in this instance, but it great for lots of things. Might be worth a try?

Thank you, I have some Bar Keepers friend, so I'll give that a try first.
