Foil stuck to bottom of oven
A bit of chemistry first. Aluminum foil reacts to acid. A black substance referred to as aluminum salts is formed. This is simply wiped away. How quickly the foil is converted depends on the strength of the acid. Vinegar has a safe level of acid content. Within two hours, some aluminum salt should have formed. Wipe it away. Repeat. And keep repeating until all gone. Yes, the process takes time but you can be doing something else. And the salts are black, so you don't want your clothes or hands covered by the black. Expect this to take a long time. And you may get frustrated and decide to buy a new liner! But if you work at it long enough, it will remove the foil. You may be pickled by the end of the process but repetitions of this will remove the foil ... in good time ...with enough applications and wipings. And you haven't been exposed to fumes or effects of sodium hydroxide.
