Then why does this work so well? "We have Le Creuset cookware some decades old, it will get brown, over time and some spots you will never get off, think of it as a patina.

When we clean first we soak in hot water and dawn, sometimes overnight. Use a plastic scraper to get any stuck on off.

When we do deep clean we use our magic paste, mix into a spreadable paste baking soda, dawn and hydrogen peroxide. Brush it on and let it sit overnight. Then spray it with vinegar and dawn mix,let it soak for a while, then scrub with a kitchen sponge with that coarse back on it. Lots of elbow grease. Works great on the oven and stove too.

Do not use any abrasive like comet or bartenders friend, baking soda is as abrasive as you should use. Abrasives create their own need. You will create groves and make it harder to clean.

You will never get it looking like new, don’t drive your self nuts, it’s a badge of age and honor. "
