Tips4home on Instagram: "Old baking sheets don’t have to stay brown and greasy forever. This is the simple way I clean baking sheets and remove baked-on grease so they actually look new again. No fancy tools, just a method that works when regular washing doesn’t. Safe for uncoated aluminum and stainless steel baking sheets. Not recommended for nonstick-coated sheets (can damage coating). #bakingsheetcleaning #cleaningtips #cleanwithme"
