What substance would do the best job of cleaning pots and pans 7 2 4or 8?

It seems like you're asking about cleaning pots and pans, but there's some missing information. The numbers "7 2 4 or 8" don't make sense in this context.

To help you find the best cleaning substance, please tell me:

* What kind of pots and pans are you cleaning? (e.g., stainless steel, cast iron, nonstick)

* What kind of food residue are you trying to remove? (e.g., burnt food, grease, sticky sauces)

* What cleaning tools do you have available? (e.g., sponges, scrubbers, dishcloths)

Once I have this information, I can provide you with specific recommendations for the best cleaning substance.
