You only need three things: hydrogen peroxide (regular, XNUMX%), baking soda, and patience. Mix the first two ingredients to make a thick paste, apply it generously to a baking sheet. And here comes the time for the third component. It is important not to start rubbing right away, although it seems that this will quickly get rid of the baking sheet, but leave it alone and do something else. Maybe more enjoyable.
If you give the cleaning paste time to act on the dirt, you won’t have to rub anything: the burnt-in layer will come off on its own, you just have to wash the baking sheet. Hands will be more intact, and it will take less time to clean.
You can use a duet of soda and hydrogen peroxide in another combination: first sprinkle the dirt with soda, then spray with peroxide, and add another layer of soda on top. All this happiness needs to be left on the sidelines for two hours, and the soda and peroxide will do all the hard work for you.
By the way
If you have aluminum baking trays (or any other utensils), you should never clean them with a metal sponge. The steel springs of the sponge are tougher than soft aluminum, they damage the surface, and metal particles even remain in the walls of the dishes. As a result, pots and baking trays become dull, get dirty more and rust quickly (although aluminum does not rust).
