How do you clean a cookie sheet that has baked on grid/oils?

Try spray on oven cleaner then toss in a large plastic garbage bag and close and set in the sun for awhile then hose off.

Hydrogen Peroxide and baking soda mixture. you may need to scrub it a few times but it works great!

Use ammonia and put in a garbage bag. That's seems to be what everyone is cleaning their oven grates with and they look great!

Hello Sonya; Wipe the sheet down well with white vinegar. I use extra vinegar. Then add Baking soda and scrub well. If the Baking soda turns nasty, reapply and keep scrubbing.

If this will not cut it, Please consider purchasing Bar Keepers Friend. I use this when all else fails!!!

I hope that this helps you!! Take Care!

Hi Sonya, I read this on Pinterest. I don't know if it works or not. Sprinkle baking soda over the pan then, spray with hydrogen peroxide. Let it sit for an hour then use a green scrubber. It's supposed to come right off. Good luck!

I soak them in hot water and Cascade dishwasher detergent.

First of all, why do you want to scrub them? There is nothing wrong with your cookie sheets. Those are seasoned pans. You Don't scrub those you just wipe them off. I own a pizza shop and we never scrub our pizza pans. They are seasoned because that's the only thing they're used for.

Submerge in boiling water in sink and leave overnight. It will soften it enough to be able to scrape it off with a sharp razer blade.
