I happened upon this post about three weeks ago. Went to the garage with a glass jar and 1/2 pint of white vinegar and placed a chunk of 0000 steel wool in the bottle (yes, with the vinegar). About one third of a roll.
Went out today, saw it sitting in the back corner, right where I left it. Thought to myself I would give it a go.
I stirred the mixture, (now almost nothing but filings in the liquid), then stirred the mixture with three different stir sticks, one pine, one oak and one walnut. All I got was three wet stir sticks - NO color change whatsoever.
