## Abstract

A cleaning composition with a limited number of natural ingredients contains an anionic surfactant, a nonionic surfactant, a solvent and a short chain syndetic. The cleaning composition can be used to clean laundry, soft surfaces, and hard surfaces and cleans as well or better than commercial compositions containing synthetically derived cleaning agents.
