Question about cleaning pans using the black bag/ammonia method...

[Phentex]

I know it works on stove pans and grates and I just used this successfully on a big green egg pan (the bbq was worth the mess!) but does it work on regular cookie sheets or toaster oven pans?

For those who have not seen it mentioned I think it was Warpy who described this method. You place pans in a black trash bag, spray them with ammonia, tie up the bag and let it sit in the sun for a few hours. The crud comes right off.

1. It will work on anything coated with dried grease

What the black bag does is absorb infrared efficiently, heating the contents. Grease + strong alkali + heat = eventual saponification. In shorter words, it turns into soap, which rinses right off.

The hotter the day, the better it works.

Just don't forget the mask and eye protection when you're spraying everything down with that ammonia! You don't want to breathe droplets and you don't want them in your eyes.

2. Baked on grease?

Can it be used on copper bottom pans?
