I have a fairly new, rarely used Revereware pan. No copper bottom. It has a
spout on it. I bought it specifically to make ginger tea but I no longer
make that.

The problem? Somebody Kuthed it!

The culprit won't tell me what he did but it appears to be a layer of burned
on sugar that was followed up by another layer of instant oatmeal. As in
many packets of oatmeal and water, but somehow the sugar or honey or
whatever it is underneath that, not mixed in.

The burned part is not a solid layer. It comes up around the sides of the
pan by about 1/2 an inch. There are spots on the bottom that didn't get
burned, but most of it is.

My standard treatment is to cover with baking soda and hot water. I used to
boil this but discovered that hot tap water works just as well. I did this
method many times. It did bubble off some of the burned stuff, but not all.

I scraped some off with a butter knife. Only a tiny bit came off.

Pan scraper didn't work.

Green scrubber did nothing.

Brillo pad didn't do much.

I have resorted to boiling water in it repeatedly. This is loosened a few
specks. At the rate I'm going, I might get it clean by 2022.

Help! What else can I try? Thanks!
