A composition is disclosed useful for cleaning hard and soft contact lenses, in which cleansing action is provided by a relatively soft abradant particulate sparingly soluble room temperature solid organic acid or inorganic salt, preferably in combination with one or more surfactants. The particulate material effectively removes deposits from the lens, and readily dissolves on the application of water. Disclosed is also the method removing surface deposits from a contact lens by use of the above composition.
