So I was getting ready to sell my Tibetan Ti 1100 pot and it was a bit black and crusty from being used with a Bushbuddy wood stove. I tried to clean it, as I have tried before, with dishwasher liquid and a scotchbrite pad, but once again had very limted success. I asked my wife about it and she handed me this "Magic Eraser" spongy thingy from Mr. Clean. I was pretty skeptical at first, but with a little elbow grease the black and brown gunk began to disappear. In about 20 minutes I had the pot looking almost new again, except for a few stubborn black spots on the bottom. Here's before:
And here's after:
So I tried it on my SP600 mug which has been getting a little blackened from alcohol tests, and it cleaned that up pretty nice too. Not quite as nice, but nice.
Anyway, I'm not usually one to hawk cleaning products but I thought some of you might find this handy for your stubborn pots and mugs. Good luck!
