Hi, I have a more than half decade old aluminum kettle at home. It hasn’t been used for a while because the outside is all covered with kitchen grease for sitting in the kitchen closet for years.
I think cleaning with just plain soap will probably involve a lot of hard scrubbing at certain spots. But that’ll probably mean these spots will be scrubbed so much that it will look shiny aluminum while other spots that don’t require extensive scrubbing will look different.
Are there other better solution that allows me to more easily remove the grease?
Separately, the inside of the kettle is now quite blackish, probably because of prolonged oxidation of the aluminum in the air. Any suggestions on how to remove the oxidation besides scrubbing?
