A poster did mention that above, and I neglected to acknowledge that when mentioned the first time, but I am familiar with it, and own some in both liquid and powder varieties. It works great on my stainless sinks, and any other surfaces I'm willing to impart the odd scratch or two to, but maybe I'm in the stages of my pit ownership where I'm looking for a solution that doesn't scratch. Barkeepers friend is an abrasive. I'm aware of the "with the grain" concept, but I'd just as soon do it with a paper towel and warm soapy water if that'll work. Unfortunately that won't--but I have found that vinegar will. I'm just sure to remove any vinegar residue afterwards, and it's like the smoke wasn't even there. No abrasive needed. Lucky break.
