What is the best way to clean the bottom of pots and pans

Brillo pads.

ok what pots and pans???When asking a question you need to specify all information.This web site is for real is your question

I spray with oven cleaner

Bon Ami, Bartender's Friend, Brillo pad, baking soda and vinegar (yes, the combination is fun, but helpful), Comet and water. I usually soak them in hot-warm dishwater to loosen things up and then scrub.

I'm not a fan of oven cleaners, even in the oven, but it does work.

Mr. Clean Magical eraser is the easiest way. Use gloves

will try it...thanks!

Try on stainless steel only... Spray with a top brand oven cleaner like ( Easy Off ) Let set over night if possible... Next morning spray off with water for a shining pan .... Also works on clear glass baking dishes( not colored ) ..... Never use on aluminum !!!

If they are copper bottomed pans (i.e. Revere Ware) a coating of ketchup (the acid helps) or toothpaste (like Crest) (mildly abrasive) will start removing the gunk, then use a copper cleaner or Bartender's friend and some elbow grease!
