NEW YORKRepresentatives for Palmolive dish detergent issued a challenge to the makers of Dawn Monday, charging that the blue dishwashing soap 'coddles grease.' 'Palmolive lives up to its vow to be 'tough on grease,' but Dawn merely 'takes grease out of your way,'' Colgate-Palmolive CEO Reuben Mark said. 'Out of sight, out of mind, eh Dawn? Palmolive believes in eradicating the grease problem, not simply pushing it to the far reaches of the sink.' Mark added that, as unrelenting as Palmolive is on grease, it continues to be soft on hands.
