Boiling Potatoes Turned My Pot Black?
I recently bought a very large 16qt heavy aluminum stock pot to use for various purposes.
Since I had to boil 6lbs of potatoes for a party tomorrow, I decided to use my nice new pot.
They potatoes came out fine... but now the inside of the pot is completely black, not charred... but the aluminum has turned dark black.
What happened? Has it hurt the pot or the potatoes beyond repair?
And is there a way to clean it.
Barkeeper's friend works wonders. I don't have aluminum pots, but stainless, enameled cast iron and anodized aluminum and it's cleaned up the most terrible messes incredibly well. It is abrasive, though (although my cast iron hasn't suffered for it yet); but it is "natural" apparently and is my favorite miracle cleaner for everything from rusted hardware, to burned-on food, to stubborn tub stains. Give it a try by pasting it with some water, letting it stick and using a soft cloth to clean (or steel wool if the pot is the sturdy type).
Hard water turned my aluminum pots dark and white.
At home they turned dark, according to the water company it was magnesium or manganese (I don't recall), at the cabin they turned white, according to a neighbor it was due to calcium.
The water company suggested cleaning with vinegar or cooking something acidic.
