Using oven cleaner on aluminum... BIG MISTAKE! I learned the hard way. Many years back we found this cool vintage oven/stove with tons of aluminum bright work and chrome trim, all in great shape. It was greasy as can be, which had perfectly preserved the finish underneath.
Now what better to clean an oven with than oven cleaner right? I went to work on that thing with a can of Easy-Off... covered the whole thing... emptied the can.
OK, lets let it soften up and start bubbling then wipe it off.. I can hardly wait to see it shine!
As I'm standing there waiting and watching this stuff do all the hard work for me, I can see the aluminum panels and knobs and stuff start to turn white. What the...?
I quickly grabbed a rag and started wiping it off. To my horror, the aluminum was all dull and milky colored. Permanently etched. All of it, RUINED!
That stove has been in use in our kitchen since then, and every time It catches my eye, I am reminded of how stupid I am... or was.
