Baking Trays200 offers*
If in doubt, measure the old tray and use the values as a guide.
You can also melt the butter or margarine and apply it with a pastry brush.
Add a little semolina, flour or breadcrumbs to the greased tray for an extra non-stick effect and to make your baked goods even easier to lift out.
For example, if you spread salt on a baking tray and put it in the oven at 50 degrees for about an hour, it will help against burnt-in food. If the salt has turned brown, take the tray out, shake off the salt and wipe the tray clean.
Another trick is baking soda. Just put some water on the baking sheet and let it soak for a bit. Then pour a packet of baking soda into the water and let the mixture soak in. Afterwards, you can simply wipe off the loosened dirt.
Dishwasher tablets also work wonders. Fill the tray with boiling water, dissolve a tab in it and put the tray and water in the oven for an hour.
Therefore, load the tray evenly and do not leave it in the oven during preheating.
If this is too inconvenient, put it on the street at the next bulky waste collection.
The residual waste bin is not the right choice. If you put old baking sheets in there, they go straight to the incinerator and the opportunity for environmentally friendly reuse is not taken.
