After the aluminum foil is electrochemically corroded, it is necessary to use chemical methods to oxidize its appearance to aluminum oxide, which is the medium of aluminum electrolytic capacitors. After oxidation, carefully review the appearance of aluminum oxide to see if there are freckles or cracks, which will be insufficiently removed.
