Agreed - that's what i said above, wipe out has none.

and i certainly feel better about letting it sit overnight in my barrels.

i would like to know where you're getting it for 7.00/can though.

my experience is as such...

let it sit first night and all copper comes out (blue liquid)

let it sit a second night and black comes out on the patch (powder)

let it sit a third night and the patches come out white.

takes about 10-patches and no brushes.
