Paderno Pots / How to clean aluminum bottoms
I have some Paderno Pots ( Pots from Eternity line). The bottoms have solid aluminum with concentric ridged rings. I am having trouble cleaning in between the ridges. There are either brown discoloured or brown soiled areas on the bottoms. I was told to use an oven cleaner, but when I read Easy Off directions it says not to use on aluminum. I have tried aluminum cleaner and also an SOS pad and nothing touches the brown. Help!!
