Abstract

A composition for washing the exterior of railway carriages and the like consisting of an aqueous dispersion containing pectin as the thickening agent, and possibly xanthan gum and sorbitol, and having acid pH due to the presence of one or more mineral or organic acids chosen from the group of acids able to dissolve iron oxide. Said composition is prepared by firstly mixing the pectin and if present the xanthan gum and sorbitol with water at 60-85 DEG C, and then adding the acid or acids at 35-40 DEG C. The composition obtained has advantages of applicational and ecological character.
