What you also have to take into account is (strong) magnetic fields. These can make all information stored on the cards unreadable. It seems best to me to store all cards in a metal box, which keeps out all magnetic fields. If you also add some water-absorbing granules in a cotton bag, you will probably get rid of the oxidation.
I use HP-16C, WP-34S emulator, HP-35s, HP-48GX, HP-50g, and HP Prime G2.
