There is Jasco Metal Prep which has phosphoric acid in it and it will etch stainless, also a three day soak in apple cider vinegar will do it too. The Metal Prep turns rust into iron phosphate or black iron and it will instantly etch aluminum. Most paint stores sell it, it is also called Ospho.

Tho the phosphoric acid is watered way down watch your blade as this stuff is aggressive.
