Abstract There is provided a stable paste comprising a diethanolamide of a fatty acid having 12-16 carbon atoms, sodium bicarbonate, sodium chloride, and water. In another embodiment, this paste is admixed with a paste of the diethanolamide, sodium chloride, and a saturated solution of sodium chloride. Both formulations can be used full strength for scrubbing stubborn stains, scuff marks and the like and diluted for cleaning surfaces, such as floors and walls.
