Abstract
At least a substantial amount of the corrosion products on the surface(s) of brass plated steel cord are removed by treatment in an aqueous solution containing a minor amount of an NH.sub.4, Na, K, Li, Ca, Mg, Sr, Ba and Zn salt of a saturated aliphatic carboxylic acid of from 1 to 5 carbon atoms.

The method which comprises dipping brass plated steel cord in an aqueous solution consisting essentially of from about 0.5 to 6.0 percent by weight of at least one salt selected from the group consisting of the NH.sub.4, Na, K, Li, Ca, Mg, Sr, Ba and Zn salts of a saturated aliphatic monocarboxylic acid selected from the group consisting of formic, acetic, propionic, n-butyric, isobutyric, valeric and isovaleric acids and mixtures thereof for a time and at a temperature sufficient to remove at least a substantial amount of the corrosion products on the outer surface layers of said cord and then drying the same.
