Abstract
A brush using water alone to clean up toilets, baths, kitchens, tableware, kitchen utensils or the like. Phosphate ingredients contained in the higher alcoholic type detergents and nonionic detergents currently in use do enhance the cleansing effect, but are nutritive substances to plankton and the cause of its abnormal propagation. Resulting pollution of rivers, lakes and marshes, in particular their coasts, has been a social problem to be solved as soon as possible. The present cleaning brush can remove ordinary dirt, stains or the like, without using such pollution-causing detergents.
