Abstract

The present invention relates to pretreater or compositions in stick form which remove stains. The compositions contain 30 to 80 wt. % of a nonionic surfactant, 1 to about 20 wt. % of an anionic soap, and 0.1% to 10 wt. % of a hydrophobically modified polar polymer. A method of using the composition is also described.
